The names of all sensors on sensors for early auto engines

The reasons for the car engine fault light to turn on include sensors for early auto engines, maintenance problems, oil quality problems, poor mixture combustion, air intake problems, etc. These problems may cause the car engine fault light to turn on. The fault light of the engine needs to go to 4s to read the fault code with a special computer diagnostic instrument, and then check and repair according to the fault code.

1. The problem of sensors for early auto engines
The sensors for early auto engines mentioned here include water temperature, crankshaft position, air flow, intake air temperature, oxygen sensors for early auto engines, etc. When these sensors for early auto engines are damaged, the contact is poor or the signal is interrupted, the ECU of the car will The engine data cannot be accurately obtained, and the engine fault light will be illuminated at this time.

2. Maintenance problems
Poor engine maintenance is the most common cause of engine failure lights. Vehicles all have a certain maintenance cycle. If the owner does not maintain it on schedule, coupled with bad driving habits, it will increase the burden of engine operation. In the end, the fault light can only remind you to take care of your car. .

3. Oil quality problem
The fuel that the car fills is generally marked, and the oil is also divided into semi-synthetic and fully synthetic. The manufacturer generally recommends which type of fuel and which type of oil the car owner should use. It will cause wear and tear of the engine, and the fault light is not to blame.

4. Poor combustion of the mixture
Engine spark plug failure, ignition coil failure, fuel pump failure, oil circuit blockage, etc. will cause poor combustion of the engine mixture. The poor combustion of the mixture is caused by carbon deposition or knocking in the engine, and these will eventually be detected by the engine's oxygen sensors for early auto engines. After reporting to the ECU, the fault light will naturally turn on as a warning.

5. Air intake problem
When the engine burns, it needs air intake. In this process, the air filter element is very important. If the air filter element of the car is not clean, it will affect the air intake of the car if it is not cleaned regularly. This may cause blockage in the long run. It will cause the engine malfunction light to come on.
The fault light of the engine is generally due to the electronic control system of the engine, the sensors for early auto engines, the line is faulty, and then the fault light is on. Go to 4s to read the fault code with a special computer diagnostic instrument, you will probably know where the problem is, and then check and repair according to the fault code. Generally, the control indicator light comes on when the ignition switch is turned on, and goes out shortly after the engine is started. If the engine failure light is still on after the engine is started normally, it is necessary to check and repair it in time.
