There are many sensors in the car, some of which will affect driving if damaged, while others will not. Next, Bian Xiao will tell you several common sensors, including intake pressure sensor, water temperature sensor, oil pressure sensor and camshaft position sensor.
1. Intake pressure sensor: when the sensor fails, the engine fault lamp on the instrument panel will light up. As soon as the vehicle steps on the accelerator, black smoke will come out of the exhaust pipe. The engine will have insufficient power when driving, and the acceleration will be weak.
2. Water temperature sensor: when the sensor fails and the water temperature signal cannot be detected or the detected water temperature signal is abnormal when the vehicle is driving, the on-board system will control the engine output to protect the engine. The engine fault lamp on the instrument panel will light up, resulting in insufficient power and weak acceleration.
3. Oil pressure sensor: Generally speaking, the vehicle will have two oil pressure sensors, one is high pressure and the other is low pressure. Whether the high pressure or low pressure is damaged, the engine fault lamp and oil fault lamp on the instrument panel will always be on. Sudden stalling may occur when the vehicle is driving, which may cause the engine to pull cylinder in severe cases.
4. Camshaft position sensor: when the sensor fails, it will cause difficulty in starting the vehicle, sometimes it takes a long time to start. When the vehicle is running, the idle speed will be unstable and the engine will not accelerate smoothly
