Reasons for damage of fit sensor

The common damage causes of Fit sensor are short circuit or sensor itself damage. Multiple sensors are installed in the car, and different sensors have different functions and installation positions. There is no time limit for the use of the sensor, but once it is damaged, it must be replaced in time, otherwise it will affect the driving safety of the vehicle. Damage to the sensor will have the following effects: 1. Symptoms of damage to the speed sensor are: the engine is unstable at idle speed; When the vehicle slows down and stops while starting or driving, there is an instantaneous pause or flameout phenomenon; Engine acceleration performance decreases; There is a deviation in the speed display on the instrument; The engine fault light is on. 2. The damage of the throttle position sensor will lead to the correct ignition advance angle and the air-fuel ratio imbalance of the mixture. The throttle position sensor should be accurately adjusted to the specified voltage reading. Too low adjustment will lead to the exhaust gas recirculation system can not provide enough exhaust gas in time, and it is easy to knock when accelerating; Too high adjustment will lead to too fast exhaust gas recirculation reaction, provide too much exhaust gas and reduce power. 3. Damage to the coolant temperature sensor will lead to engine idling instability, fire, flameout or increased fuel consumption. According to the manufacturer's regulations, the resistance value of the coolant sensor should be tested with a multimeter at different working temperatures. There is a body height sensor at the suspension, and the body height will change due to different load conditions. According to the change of body height, the headlight height will be adjusted automatically.
