Engine 4216 Euro 3 is recommended for installation on Gazelle cars. But many motorists were faced with the fact that when operating the engine, tripping appeared.
What are the specific circumstances of the origin of the result and how to respond independently.
Device and Specifications
Before we move on specifically to the consideration of the circumstances under which the engine fails, and in addition to the methods of response, let’s look at the main characteristics of the power unit. As practice has shown, the power unit has high performance, and based on this, it is loved by many car enthusiasts.
Simple reliability and design made the engine widespread among owners of Gazelle cars. Let's look at the main characteristics of the power unit:
This type of engine was used on Gazelle Business and Next vehicles.
Circumstances of engine tripping
Any engine tends to break down. Thus, the UMZ 4216 E-3 is also susceptible to malfunctions.
There is one SKODA RAPID car for everyone
SKODA RAPID is a car that can safely be called unique. Why? The answer is obvious - it will suit absolutely everyone! The dynamic character of the model and precise, refined handling combined with an interesting and stylish design will not leave the younger generation indifferent.
Older drivers will appreciate the nobility of the “crystalline” design, which is partly reminiscent of the traditions of the best crystal manufactories in the Czech Republic and the cubist architecture so beloved by all residents of Prague.
The engine check is blinking or the main reasons are on:
On the VAZ 2115, a common error that causes a check to appear is p0300. She tells an experienced mechanic that the engine is misfiring. The fuel mixture is not ignited in time.
And there may be several reasons why these omissions occur. Failures are found in a variety of engine elements. There is no such thing that the error only indicates, for example, a faulty cylinder.
Sensors and ECU
If the check is blinking and the engine of a VAZ 2114 car is shaking, first check the ECU and the functionality of the sensors. On this car, and on others as well, sensors are often damaged. They break or stop working properly due to heat, severe frost or other conditions. Sensor failures also occur due to poor-quality material from which they are made. For example, it could be a Chinese counterfeit.
The ECU may malfunction if the car is old and has been used in harsh operating conditions. If the electronics themselves reduce fuel consumption, and the car owner resets the error through the battery and does not eliminate the error by replacing the ECU, this may lead to a major overhaul of the engine. Because reducing the fuel supply leads to a reduction in the life of the engine.
Fuel and its supply components
Problems with injectors and fuel quality lead to engine stalling and check marks. Despite the fact that Kalina engines are assembled at domestic factories, according to modern requirements, they consume fuel with a high octane number. Therefore, experienced mechanics do not recommend using fuel below AI 95.
The next reasons for engine malfunction and due to which the check may blink may be malfunctions in the injection nozzles. These engine parts are diagnosed on a special stand. Experienced mechanics check how electricity is supplied to the injectors and the condition of the seals.

Valves also burn out. This leads to a decrease in pressure in the power unit. And damage to the distributor leads to the fact that sparks do not reach the spark plugs, or they do, but with a delay. In this case, it is necessary to look at the operation of the bushing or bearing and shaft. These parts may be worn out.
As a result of previous occurrences, gaps appear between the contacts. They cause bars to be skipped. The engine stalls when the car is just started, that is, when it is cold. When the engine warms up, the tripping may disappear because expansion occurs and the gaps decrease.
Air
Due to the problem described above, the lambda probe or oxygen sensor may fail. The catalyst will break. Therefore, it is not recommended to drive a car when the check mark is flashing and the engine is shaking.
You can solve the problem yourself. In this case, the car owner must do the following:
- Measures compression to be sure that the problem is due to the reason described above.
- Then remove the cylinder head.
- The head needs to be defective and checked for malfunctions.
- Replaces a burnt out valve.
On 8-valve engines, problems can be observed in the operation of the injector or injection device. If necessary, it is also replaced.
Air may also be sucked into the vacuum brakes. When their seal is broken, air leaks cause the check mark to burn on the dashboard. In this case, the engine suffers because the air depletes the fuel mixture. The candles are getting wet. As a result, the fuel does not ignite because no spark is produced.
High voltage wires and spark plugs
High-voltage wires of the VAZ 2114 can also be damaged. The spark plugs fail and flood. These problems cause the check light to light up and the engine to stall. A break in the circuit of high-voltage wires leads to the fact that ignition does not occur. No spark is produced.
In this case, the engine may even stall. To prevent this from happening at the first signs of tripping, it is necessary to take the engine for diagnostics.

What is engine tripping?
When the check light comes on, the power unit may operate unstably. The automatic transmission handle jerks. The engine stalls and has to be started again. These problems can arise due to various malfunctions with the internal parts of the engine.
A malfunction signal is sent to the engine electronic device unit or, simply, a computer. Where it is read by the brain and sent to the dashboard screen. The driver sees this signal and must take certain corrective actions.
Attention! When a check appears in a car with an eight-valve or sixteen-valve engine, you need to go to a service center to have the vehicle inspected. Further delay leads to discarding the unit and purchasing a new one.
If the engine still stalls when the check lamp comes on, this indicates the following engine malfunctions:
- possible damage to the catalyst;
- improper operation of valves or cylinders;
- fuel combustion occurs incorrectly;
- The ignition system is faulty.
These are only part of the reasons why the engine may stall. We will look at others in the next block. In any case, experienced mechanics do not recommend fixing the problem with the check on your own. Especially if the driver simply resets the check through the battery. Such a reset leads to such an outcome that all errors in the engine brain are reset to zero. And it is more difficult for experienced mechanics to find a breakdown in the engine.

4216 engine on and off in the Gazelle : prerequisites
Owners using the engine
UMP 4216 are having trouble starting the unit and here the Check Engine light is flashing. How to fix this failure and what is the reason for its occurrence.
Characteristics
Before we consider in detail the malfunctions associated with the operation and flashing of the “CHEK” on the dashboard of the Gazelle Business
", it is necessary to consider the technical characteristics of UMZ 4216:
Error and solutions
The prerequisites for the triple and flashing "Check" are almost identical for all units. The main reason is the incorrect formation of the air-fuel mixture.
, as this is called a breakdown in the ignition system. But it's okay.
Bad fuel
Poor gasoline and ordinary buttocks clog the fuel elements, and the injection system itself forms a poor mixture. Nozzles should be inspected for diagnosis and troubleshooting. It is best for our client to perform this operation on a special shield. If the elements are found to be clogged, it means that the car was running on bad fuel.
Another condition is a clogged fuel filter, which is recommended to be changed every 20,000 km. It is also worth studying the characteristics of the fuel pump, which may fail.
Replacement
The repair did not help, and you decided to replace the phase sensor? The price for an original spare part varies from 250 to 400 rubles. The cost depends on the store; it is best to order online. Before purchasing, make sure that the sensor is truly original, there are no extraneous inscriptions, chips or paint stains on it. All this can give away a low-quality fake.

The part has been purchased, and now you need to install it in place of the old one. To replace the phase sensor on UMZ 4216:
- Press the engine management system wiring harness retainer and disconnect it. Carefully remove the tension roller of the cooling fan drive.
- Disconnect the wiring harness block from the phase sensor and remove it from the holder. It is attached to the timing cover.
- Using a slotted screwdriver, remove all fasteners connecting the timing cover and the timing sensor.
- Remove the element from the socket and install a new one.
- Reassemble the mechanism in reverse order. Check its functionality by starting the engine.
The procedure itself takes minimal time and can be done independently. But, if you are not confident in your abilities and are afraid of damaging other elements, it is better to contact a salon. Any auto repair shop provides the service for replacing the camshaft sensor.
Hello guys, I’m boiling, I’m tired of changing phase sensors... In short, because of the low cost, I always bought sensors, to be honest, a rare g...o. Over the past 3 months I have changed 5 pieces. 1 sensor either works or doesn’t... the second worked for a month, the third did not give an error, but the car crashed at medium speeds, 4 from the store was not working, 5 worked only after the car heated up to 90 degrees. I was fed up with this; the price of this sensor is 300-400 rubles, the quality does not shine. defect rate 80%
A better option from the ELKAR company, it lasts longer, and the external quality is completely different, much better, the machine runs noticeably smoother on it. issue price 550 rub. Now I have one, it’s something between “Boshevsky” and “ROMBovsky”.
BOSCH, the best option in terms of reliability, but also the price is 800 rubles. a little big, but the percentage of defects is minimal.
Have a nice weekend everyone, write who has which sensor and who suffered with them.

Crankshaft position sensor - frequency sensor 23.3847 or 406.387060-01.
The sensor is of inductive type, works in tandem with a synchronization disk having 60 teeth, two of which are removed. The cutting of the teeth is a phase mark of the position of the engine crankshaft. The beginning of the 20th tooth of the disk corresponds to TDC of the first or fourth cylinders of the engine. The counting of teeth begins after cutting along the direction of rotation of the crankshaft.
The sensor serves to synchronize the control phases of the system's electrical mechanisms with the operating phases of the engine's gas distribution mechanism. Installed at the front of the engine, on the right, on the flange of the camshaft gear cover. The nominal gap between the end of the sensor and the tooth of the synchronization disk should be in the range of 0.5-1.2 mm. The sensor is connected to the wiring harness using a three-pin socket with a latch.
