If the engine of the car fails due to poor combustion of the mixture, go to the repair shop in time to interpret the engine fault code to solve the problem.

There are many reasons for the failure of the car engine, including the failure of sensors, such as water temperature sensors, crankshaft sensors, oxygen sensors, etc.; There are also other faults like spark plug failure, ignition coil failure, fuel pump failure, oil circuit blockage, etc.

The ECU controls all the electronic equipment of the entire engine, such as electronic throttle valves, fuel injectors, generators, fuel pumps, etc., covering various systems such as air intake, exhaust, fuel, ignition, and timing.

In the case of engine failure caused by poor combustion of mixed gas, go to the ZHI repair shop in time to decode the engine fault code to solve the problem.

Hello! If the fault light is on, it is best to use a special instrument to detect it! If you are troublesome and not afraid of problems, you can also disassemble a battery cable! Wait about 30 seconds before picking it up! Occasional glitches will be cleared! High-end cars should be used with caution.

Just washed the throttle. The mixture will be too thick, so the computer will record the kind of occasional failure, when driving a distance, that situation disappears, so the fault lamp will go out by itself, I don't believe you can use the computer to read the fault code, it must show the occasional failure, the lamp should be the discharge fault lamp, the ignition instant idle speed is almost 2000, down to 1000, I think it is still a bit high, the four-cylinder engine is generally between 750 and 850, check the idle motor.

Cleaning throttle mechanics do not work seriously! The fault light is on after the throttle is disassembled and cleaned from the car, because the throttle position sensor line is not connected properly when it is installed, or the ignition starts the vehicle when the throttle is not fully returned, causing the sensor signal to be abnormal. After re-checking the circuit, the fault can be solved by initializing the throttle with the computer.

You need to go to the 4S store to automatically learn it with a special manufacturer's computer and restore the original factory settings.

Hello, did you wash the car directly by stepping on the accelerator?

That's because the cleaning fluid and the gasoline in the fuel injector cause the mixture to be too thick, and the oxygen sensor gives the computer a wrong signal, so as to light up the fault light, if the car is sending everything normally, the fault code can be eliminated. [Car questions, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

Solution: After the throttle is cleaned, the fault light is on. After re-checking the line at the 4S shop, initialize the throttle with a computer to resolve the fault.

This is because when the throttle position sensor is installed back, the line is not properly connected to the fuel lease, or the throttle is not fully returned, the vehicle will ignite and start, resulting in abnormal sensor signals.

The throttle is a component above the intake system. Its main function is to control the air intake. The variable it corresponds to is the response of how many accelerator steps are taken. If you press the throttle more, the throttle will open more and the intake will be more.

Throttle failure can cause the cylinder to not close and an air leak. If the pressure in the cylinder is not enough, it is difficult to ignite (there are also high voltages, that is, the pressure in the cylinder and the compression temperature of the mixed gas do not reach the ignition conditions). In severe cases, the cold engine cannot catch the car, the combustion is not complete, the locomotive has no power, and it will also cause farting (the sound of the exhaust pipe cannon).

There are two types of throttle valves: traditional pull wire throttles and electronic throttle valves. The traditional engine throttle control mechanism works through a pull wire (soft steel wire) or a pull rod, and one end of the pull wire is connected with the oil skin Ming Zhao pedal, and the other end of the pull rod is connected with the throttle linkage plate.

The electronic throttle valve mainly uses the throttle position sensor to control the opening angle of the throttle according to the energy required by the engine, so as to adjust the air intake.

Check more to check whether all parts are installed, if there is indeed no human error, remove the negative electrode of the battery, and then connect it with the reputation. If the chaos recurs, it is most likely that the three-way catalytic converter of the exhaust pipe needs to be cleaned.

Hello, the engine fault light may be caused by one of the following reasons 1, sensor problems include water temperature, crankshaft position, air flow, intake air temperature, oxygen sensor, etc., when these sensors are damaged, poor contact or signal interruption, the ECU of the car can not accurately obtain the engine data, at this time it will cause the engine fault light to be on.

2: Maintenance Problems Poor engine maintenance is the most common cause of engine failure to light up.

3. Oil quality problems We are talking about the oil quality here includes fuel and engine oil, the fuel filled by the car is generally marked, and the engine oil is also semi-synthetic and fully synthetic, the manufacturer will generally recommend the owner to use which grade of fuel, what type of engine oil, if the owner does not add as required, it will cause wear and tear of the engine in the long run.

4. Poor combustion of the mixture The failure of the spark plug, ignition coil, fuel pump, and oil circuit blockage of the engine will cause poor combustion of the engine mixture. Poor combustion of the mixture is caused by engine carbon deposition or knocking problems, and these will eventually be detected by the engine's oxygen sensor, and after being reported to the ECU, the fault light will naturally be lit as a warning.

The car engine fault indicator light on, indicating that the engine is indeed faulty, and the cause of the failure is attributed to the quality of the oil is unreasonable, the car is still under warranty, the manufacturer or 4S shop has the responsibility and obligation to replace the bad parts for free! Good luck!

The reasons are as follows, for reference only: 1. The sensor is damaged, the contact is poor or the signal cover is interrupted, and the computer will report the code if it has a storage function; 2. Poor engine maintenance; 3. The quality of fuel and oil is not good; 4. The combustion of the mixture is insufficient; 5. Spark plug failure, ignition coil failure; 6. The fuel pump is faulty and the oil circuit is blocked; 7. The air conditioning filter is blocked, and 8. The engine itself is caused by mechanical failure.

The specific analysis is as follows; 1. Sensor problems; Sensors include water temperature, crankshaft position, air flow, intake air temperature, oxygen sensor, etc., throttle position, accelerator pedal position sensor, when these sensors are damaged, poor contact or interrupted by the letter of the cress horn, the ECU of the car can not accurately obtain the engine data, at this time it will cause the engine fault light to be on, and the power of the engine will also be affected. 2. Maintenance problems; Poor engine maintenance is the most common cause of engine failure to light up. We know that the vehicle has a certain maintenance cycle, if the owner does not maintain on time, coupled with bad driving habits, then it will increase the burden of engine operation, and finally can only remind you through the fault light to care about your car 3, oil quality problems; The oil quality here includes fuel and engine oil, we know that the fuel filled by the car is generally marked, and the engine oil is also semi-synthetic and fully synthetic, the manufacturer will generally recommend the owner to use which grade of fuel, which type of engine oil, if the owner does not add as required, it will cause wear and tear of the engine in the long run, and the fault light is not to blame.

Poor combustion of the mixture; The failure of the spark plug, ignition coil, fuel pump, and oil circuit blockage of the engine will cause poor combustion of the engine mixture. Poor combustion of the mixture is caused by the problem of engine carbon deposition or knocking, which will eventually be detected by the engine's oxygen sensor and reported to the ECU, which will naturally light up the first hunger barrier light to warn of the air intake problem; When the engine burns, it needs to take intake, and the air filter is very important in this process, if the air filter of the car is not clean, it will affect the supercharger of the car if it is not cleaned regularly, and it will also cause the engine failure light to be lit. The most common of these is turbocharger damage, and at the same time, the vehicle will also have oil leakage, large oil consumption, and power loss.
