These sensors are most afraid of being dirty

Jan 04, 2019

The working principle of the engine is the same as that of human beings. They are all issued commands through the computer (brain) to control the execution of the actuator. At the same time, there are many feedback sensors transmitted to the computer, the computer analyzes, and sends commands to the actuator.

 

The following are some of the more important feedback sensors. At the same time, these sensors are most afraid of being soiled, so pay attention to cleaning!

 

1. Air flow meter

If the air filter is not changed frequently, it may cause inaccurate detection data of the air flow meter and affect the normal operation of the vehicle.

 

2. Idle speed stepper motor

If the idle speed stepper motor is too dirty, the idle speed will be unstable, and the vehicle will stall or the idle speed will be high!

 

3. Oxygen Sensor

Its function is to detect whether the engine has problems through the exhaust emission, if there is a problem, it will correct the engine computer data in the appropriate range!

Black smoke from exhaust gas, lighting of fault lights, and pungent exhaust gas may all be caused by this sensor problem!
