Chevrolet Niva error 8 what does it mean?

Why did the light come on and how to fix it

The main situations in which the indicator lights up and the recommended courses of action for the car owner:

1. If the Check engine lights up and goes out immediately when starting the car, there is no damage to the engine. The cause of the fire is most likely harmless - the fuel tank cap is lost or not screwed in properly. Just wrap it tightly and check if the warning disappears.
2. If the indicator lights up while driving, you should stop and check the wires. You may find a cable hanging loose under the hood or an open battery terminal. This applies to all attachments - wires, hoses, etc.
3. If the light flashes while driving, you should stop and check the sounds made by the engine, pay attention to the oil level, and inspect the sides of the engine. If no visually obvious violations are detected, it is recommended to drive to the nearest car service center and carry out diagnostics.
4. If the engine is running normally and the Check light is constantly flashing, there is most likely an ignition failure. You should check the spark plugs and coil, pay attention to the quality of the fuel. To do this, it is better to contact the nearest auto diagnostic center.
5. If the indicator is constantly on, you need to stop, unscrew the spark plugs and check the gap. Gaps that exceed 1.3 may cause the light bulb to burn out.
6. In addition, when the “check” is on, the ignition is usually checked. Any car service center has special testers that allow you to determine the wear of wiring insulation.
7. A faulty fuel pump can also cause the light to come on. You should stop and listen to the sounds the fuel pump makes. A smooth hum without clicks or pauses is considered normal. If extraneous sounds appear, the pump should be dismantled, washed inside and the filter cleaned.
8. Serious engine malfunctions can be indicated by the coolant temperature. If it is above 85–90 degrees, and the Check engine lights up while driving, the engine is definitely faulty. In this case, it is advisable to call a tow truck or drive at low speed to the nearest car service center.

Diagnosis of errors on Hyundai Solaris

If the CHECK light comes on when you start the engine, then there is no need to worry. But if the check light is on when the engine has already started, then you need to find out the cause of the error.

The vehicle owner may need to diagnose and remove errors that occur on the Hyundai Solaris in various situations when there is no desire to do this work in a certified service center.

It is not difficult to do this work, the main thing is to know that you can delete errors related to the first level yourself, that is, those that are not recorded in the ECU memory and do not significantly affect the operation of the car and its devices. Because only a special dealer device (scanner - approx.) can remove such errors, one of these errors includes the error of the car's airbags.

Error Code 14 on Niva Chevrolet

As Self-diagnosis of Chevrolet Niva and basic error codes

Few people know that the Chevrolet Niva has a self-diagnosis feature that gives you basic error codes that can help you quickly find and fix problems with your car. 1 1 error code 14 Chevrolet Niva firmware. Without this help, it is not difficult to perform this function; just press the odometer button and turn on the ignition. The arrows on the speedometer will creep up, after the second press, information about the firmware version will appear, and the next time you press, all error codes will be shown on the monitor, unless, of course, there are faults in the car.

Error codes in Niva Chevrolet

If you see a zero on the monitor under the speedometer, you're in luck—no problems have been detected and you don't have to scratch your head to fix them. The next one is a little more complicated:

1 - malfunction in the processor;

2 - open circuit in the fuel level sensor circuit;

4 - maximum voltage in the vehicle network (more than 16 V);

8 — no voltage in the car (at least 8 V);

Car exhaust catalyst

An automobile catalyst helps a car make engine exhaust gases more environmentally friendly. It converts carbon monoxide and other harmful substances into harmless compounds. If your exhaust catalyst has become unusable, you will notice it not only when the engine icon (check) appears, but also long before that, when the car’s power drops by half. For example, when you press the gas pedal, the car will not have good acceleration dynamics as before.

What can cause a car catalyst to fail: if you regularly service your car in accordance with the car company's maintenance regulations, then the catalyst should not fail. The main reason for catalyst failure is untimely replacement of a faulty oxygen sensor, as well as non-regular replacement of spark plugs when their expiration date expires.

What needs to be done: If your catalyst has become unusable, then you cannot drive a car, since the engine will not work correctly, warning about this by an indication on the dashboard with an engine icon (check). Also, your fuel consumption will be greatly increased, and there will be no engine thrust.

Although replacing a catalyst is a very expensive repair, there is no escape from repairs. Although there is an alternative to replacing the catalyst with a flame arrester, this is not a 100 percent option. Unfortunately, if you are not an experienced auto mechanic, you will not be able to replace a faulty exhaust gas catalyst yourself.

Self-diagnosis

If it is not possible to check with a special device, then this can be done using self-diagnosis, which will help to quickly identify all problems associated with the operation of the car. To do this, press the odometer button and turn on the ignition. The speedometer needle will begin to rise to the top; by pressing again, information about the firmware will appear on the screen, and by pressing again, all existing errors will appear.

Let's take a closer look at the Chevrolet Niva error codes with decoding:

During self-diagnosis, error 8 and error 14 often appear, the first informs about problems in the brake system, and the second is related to fuel consumption, quite often this is a system glitch, but in any case you need to replace the sensor responsible for these mechanisms, or reset the memory by resetting the battery terminals.

As practice shows, knowing how to perform an independent check is very useful, since this knowledge helps to quickly identify a malfunction and eliminate it in a timely manner.

Lada 4×4 3d › logbook › the “check” light periodically lights up in the field 21214

Returning to the previous entry about the incomprehensible situation with the engine or brake pedal sensor... The burning “check engine” icon today, 08/20/2020, finally got to me and I decided to go for computer diagnostics of the car, check the Niva’s brains for possible errors. Previously, I drove around with my brother-in-law in his car those auto shops that I didn’t have time to visit in my Niva.

The new model brake pedal sensor I needed for the VAZ 21214 was not there either - all the sellers looked in amazement at the faulty sensor I was demonstrating, which I took with me, and unanimously turned their heads in different directions, saying the word “No”. Particularly advanced sellers, looking at the markings of the sensor, sent me to the foreign cars department, and my words that this sensor was installed en masse on all domestic cars with an electronic gas pedal produced in 2020 were perceived with extreme distrust.

It seems like a sensor, like a sensor, if you believe the Internet, then it is produced by a plant in Arzamas, the sensor is marked 8200168238-B, on the other side there is an inscription in English “Renault 047”. On the official website in the city of Togliatti, its cost is set at 170 rubles. In Podolsk, they tried to sell me a sensor with the same marking, but made in Spain or France, for a minimum of 2200 and a maximum of 2900 rubles.

Everything is the same, only on expensive sensors there is additionally the inscription “Made in Spain” (the inscription is made in English). Having returned home, I got into my Niva and went to a car service center for diagnostics. My guess about the malfunction of the brake light switch off sensor or the simple “frog” turned out to be correct.

Having previously visited almost all the auto shops in my city in vain, I purchased the brake pedal sensor I needed at a car service center for just the negligible price of 350! rubles The “not original” sensor, completely black, made in France, is installed on some Renault cars. But then the most interesting thing began - the Niva’s engine worked intermittently, and continued to work.

The diagnostician constantly got errors “faulty injectors 1-2” and “misfire in cylinder 1.” During two hours of being in the service center, the spark plugs, the first and second injectors, spark plug wires, compression in all cylinders, and the ignition coil were checked for serviceability. I bought new ones with return conditions - an injector, an ignition coil, DENSO spark plugs (recommended at a car service center).

The spark plugs were original and they were black from carbon deposits. I must say that the electrician-diagnostician found it difficult to determine the malfunction of my car, because... The “misfire in cylinder 1” error appeared constantly, but periodically and disappeared when the engine was restarted. “DENSO” spark plugs were installed on my Niva, and the injector and ignition coil were returned to the seller.

Afterwards, the electrician went to “call a friend” in a nearby repair bay to get advice from other repairmen. In the next box there was a VAZ 2109 with similar symptoms, but with the error “misfire in the 3rd cylinder.” In total, I was told that my fault could not be detected (everything is normal) and they advised me to change the gas station where I constantly fill up my Niva .

I already own my third car, since 2006 I have refueled at only one, the only gas station in Podolsk, and I have never had problems with the engines of my cars. Although everything in our life always happens for the first time. At a car service center, I was advised to completely drain the gasoline from the gas tank and refuel at another gas station, drive around, look, and if the “CHECK” lights up again, then go for warranty repairs to the car dealership where I bought the car.

I just recently filled the tank full. Now there is 0.75 gasoline in the tank. I’m thinking about either pouring my gasoline into a canister, or driving around to produce gasoline, not paying attention to the burning “CHECK”... In terms of money: for two hours of work they charged me “divinely” 1,000 rubles, DENSO spark plugs 700 rubles, diagnostics with removal of the “CHECK” error 500 rubles. Total - 2200 rubles.

Car diagnostics

Diagnostics of the engine and other systems and units in Chevrolet Niva, Cobalt, Lacetti, Lanos, Captiva, Cruze, Aveo 2004, 2005, 2010, 2012 and other model years allows you to timely identify the fault. Thanks to this, the car owner can prevent more serious damage. The errors themselves when diagnosing with a laptop or on a VDO display or other factory dashboard will be different. In the first case, the car owner receives the most accurate information about breakdowns, which allows them to correctly decipher and remove faults. Error combinations will be four-digit.

During self-diagnosis on the on-board computer State on the instrument panel of a VAZ 2123 or Chevrolet Tahoe, Orlando, Blazer, Lanos, Niva, Lacetti, Cruz, Captiva, Epica, Aveo in the T250 and T300 body, faults are displayed in two-digit form. Instead of combinations, messages may appear on the display to warn motorists.

Pressing the odometer button on the dashboard

How to do it yourself?

There are two ways to check for errors in a Chevrolet: self-diagnosis or using additional equipment or a computer. In order for the on-board computer to test for faults, you need to hold down the button on the odometer to reset the daily mileage and turn the key in the ignition. This will cause the needles on the speedometer and gauges to start moving along the scales. And when you press the button again, the ECU will display a message on the display about the version of the firmware being used. After the next press, combinations of problems, if any, will appear on the screen.

What codes may appear on a Chevrolet Niva after self-diagnosis:

• 1 - the microprocessor is not working correctly;
• 2 — a break was detected in the electrical circuit of the fuel level controller in the tank;
• 4 - increased voltage level in the vehicle’s on-board network, amounting to more than 16 volts, diagnostics of the battery and generator unit is required;
• 8 - the voltage in the Chevrolet electrical network is low, the same checking steps are performed;
• 12 - the control indicator is not functioning correctly;
• 13 - the control unit does not receive a signal from the lambda probe;
• 14 - the ECU received a signal about overheating of the coolant, this can lead to boiling of the engine;
• 15 - the operating temperature of the antifreeze in the cooling system is too low;
• 19 - the ECU received a signal indicating that the crankshaft is not operating correctly; we recommend testing the controller;
• 21-22 - the throttle valve is in the wrong position;
• 23-25 ​​- the intake air temperature does not correspond to the norm;
• 24 - the dashboard does not receive an impulse about the speed of the vehicle;
• 27-28 - the control unit reports violations in the level of exhaust gases;
• 33-34 - The ECU receives incorrect data on air flow;
• 35 - the power unit does not operate correctly at idle;
• 41 - an incorrect signal is received from the phase controller or camshaft sensor;
• 42 - The computer reports problems with the ignition;
• 43 - incorrect impulse from the knock sensor;
• 44-45 - incorrect composition of the combustible mixture;
• 49 - The ECU detects a loss of vacuum;
• 51 - ROM malfunction;
• 52 - The ECU has detected a RAM error;
• 53 - the control module does not receive an impulse from the exhaust gas regulator;
• 54 - the octane corrector controller does not respond;
• 55 - the load on the power unit is too high;
• 61 - the oxygen controller gives incorrect readings.

Screenshot of a computer utility for testing Niva Chevrolet

If the car’s control module has detected several problems, a number will appear on the display corresponding to all the breakdowns at once. For example, error 10 is the sum of codes 2 and 8, etc.

In the latest versions of Chevrolet, the following messages may appear on the instrument panel:

1. Change Engine Oil Soon. In the near future, you will need to change the engine oil.
2. Low Engine Oil LevelB. The lubricant level in the power unit is too low. It is necessary to check the consumables and add them to the lubrication system.
3. Oil Pressure Low - Stop Engine. The control unit has detected a low level of oil pressure in the lubrication system. It is recommended to turn off the engine and solve the problem.
4. Program Cluster. The control panel needs reprogramming. Typically, a message of this kind appears as a result of changing components on the dashboard.
5. Service Vehicle Soon. The on-board computer indicates that the vehicle is due for maintenance soon.
6. Vehicle Overspeed. The driving speed is too high, it is recommended to reset.

For detailed testing, you can use an adapter with a laptop:

1. The adapter is connected to the PC in accordance with its operating instructions.
2. The computer is connected to the diagnostic connector. It can be located on the left of the center console under the steering wheel, under the dashboard, behind the glove compartment, under the car radio. It all depends on the specific car. Check the technical documentation for location.
3. Diagnostic software starts on the PC. There are many programs on the Internet, so it is recommended to choose a utility designed specifically for a specific brand of machine.
4. A scan of all systems is started. As a result, messages with error codes will appear on the laptop screen, which must be deciphered according to technical regulations.

Diagnostic devices

To test all systems, the following scanners are allowed:

1. Universal devices. These scanners are available at almost every service station that does diagnostics. Universal devices are not full-fledged testing equipment. In fact, they sometimes produce erroneous data and do not always detect all faults.
2. Dealer devices. You will not be able to buy a specialized device in stores; it can be found from official representatives. With the help of these gadgets, you can not only determine error codes, but also interrogate control units, program keys, and even look for damage in electrical circuits.

Price

The price of the cheapest scanners today is about 600-2000 rubles, specialized devices will cost the buyer 4000 rubles or more.

Purpose of the button

The instrument panel in a car is a way for the driver to monitor the level of gasoline, oil, engine operating condition or other components of the car, which guarantee comfortable and silent driving on the road.

Modern cars are equipped with an indicator necessary for the convenience and comfort of the driver. If earlier an engine malfunction had to be found only visually or by carefully listening to the operation, today a special light bulb works. It is created for the convenience of monitoring the engine condition. Ideally, it should light up only when the engine starts and go out after a couple of seconds.

If the light does not go out or lights up while driving, then you should think about malfunctions in the operation of the main component of the car.

Check engine error

If a check light comes on on a Niva Chevrolet car, this warns that there are malfunctions associated with the operation of the engine. The light comes on at the moment when the engine begins to detect a failure or error and writes a specific code into its memory.

Let's look at the main reasons why this warning may appear:

• The air/fuel mixture is incorrect. This problem is eliminated by filling the tank with higher quality gasoline.
• Low engine oil level
• Engine overheated
• There are problems with the ignition system, which may be due to a faulty spark plug or ignition coil
• The power system is faulty. It is possible that fuel injection into one of the cylinders has stopped.
• Lambda probe faulty
• A separate sensor in the ECM system has failed

We can conclude that in some cases, when the engine starts and the check light is on, this may indicate that the engine is operating in emergency mode and the problem is not very critical. If the engine starts and stalls, then this is most likely a problem with the fuel supply or the crankshaft sensor has failed.

In any case, it is better not to use the car until you find out the exact reason.

Some drivers do chip tuning of the Chevrolet Niva in order to increase engine power. The essence of this procedure is to remove the established restrictions by adjusting the optimal factory settings in the electronic control unit. This procedure helps to extract the additional performance inherent in the motor.

The whole process can be divided into several stages:

1. Reading the necessary data from the electronic control unit
2. Making the necessary adjustments
3. Updating and recording new data

The main advantage of this procedure is:

• Engine power increases
• Speed ​​limit removed
• You can change the fuel type
• All factory settings can be returned at any time

The disadvantages include:

• High cost of work
• The ECU may fail
• Increases fuel consumption, reduces system life
• Errors may appear

Each specialist has a different attitude towards chip tuning, some consider it useful, while others think that this procedure can negatively affect the performance of the car, while reducing its service life.

Chevrolet Niva error reset

The standard procedure for resetting the controller occurs only after all faults have been completely corrected, otherwise annoying encryption will appear again. The procedure is performed in two available ways.

1. Disconnect the battery from the on-board network for 10-15 minutes. The controller will completely reboot and return to factory default settings.
2. In the BC menu, enter the “errors” service, press the daily mileage reset button and wait for the sound signal from the car, and horizontal lines should appear on the display.

Computer diagnostics

The most complete diagnosis is possible with a computer or laptop. In order to use this method, you must purchase an adapter. This adapter performs two functions at once. It is an adapter from a K-line port to a USB port or to a COM port. It also acts as a decoder, which allows you to transmit signals from the ECU to the PC. You will also need to install the appropriate software on your laptop. There are a lot of free versions on the Internet. There are universal programs, as well as programs written for a specific car. After connecting to the computer, you will need to turn on the ignition and launch the program. The connection will happen automatically.

The interface of the computer program is very convenient and allows even an inexperienced user to navigate intuitively. All functionality can be divided into several sections. These are parameters, errors and settings. If the first two sections are informational, then using the third section you can control the vehicle systems.

The Check Engine light is constantly on. I checked it for error No. 8. — if 8 appears, then there is a low supply voltage in the on-board network (below 8 V); I reset it by removing the battery for a long time, but it appears after some time. The voltage in the network is 13.5 - 14V. The battery is 2 years old. What to do, how to resolve the error?

Bottom line

The most common Niva Chevrolet computer errors are found in 90% of car diagnostic cases. There are also a large number of rare failures that are not included in the list due to their low prevalence.
