The brake sensor will not affect the acoustics

Unrelated parts, not affected.

The sensor is broken, affecting driving. The specific effects are as follows:

1. The engine fault light is on;

2. When the vehicle slows down and stops during the start or driving of the land key, there is an instantaneous pause or stallion;

3. The acceleration performance of the engine decreases;

4. There is a deviation in the speed display on the instrument;

5. It will cause the engine to idle unsteadily.

The sensor is the input device of the automotive computer system, which converts the information of various working conditions (such as vehicle speed, temperature of various rapid noise media, engine working conditions, etc.). ) is converted into an electrical signal and transmitted to a computer, so that the engine is in ideal working condition. There are many sensors used in vehicles.

When judging the fault of the sensor, it is necessary to consider not only the sensor itself, but also the entire circuit where the failure of the mu hood occurs.

1. The engine fault light is on. 2. When the vehicle starts or slows down and stops, there is an instantaneous pause or flame-off. 3. The acceleration performance of the engine decreases. 4. There is a deviation in the speed display on the dashboard. 5. It will cause instability when the engine is idling.

Damage to the vehicle's sensors will cause the central control in the car to be unable to accept relevant vehicle information, resulting in the owner not being able to understand the vehicle condition in time for trembling or hazing during driving. The vehicle sensor is the input device of the automobile computer system, which converts the information of various working conditions in the operation of the car, such as vehicle speed, temperature of various media, engine operating conditions, etc., into electrical signals and transmits them to the computer, so that the engine is in the best working condition. A broken sensor behaves like this on the car:

1. The performance of the broken vehicle speed sensor: the vehicle speed sensing function is mainly to detect the speed of the electronically controlled car, and the control computer uses this input signal to control the engine idling, the torque lock of the automatic transmission, the automatic transmission shift and the opening and closing of the engine cooling fan and cruise control and other functions;

2. Symptoms of broken sensors in the vehicle speed group: engine instability when idling; When the vehicle starts or slows down and stops, there is an instantaneous pause or stallion; Reduced engine acceleration; There is a deviation in the speed display on the meter; The engine fault light is on;

3. The performance of the throttle position sensor is broken: if the throttle position sensor is out of tune, the correct ignition advance angle and the air-fuel ratio of the mixture cannot be guaranteed. The throttle position sensor should be accurately adjusted to the specified voltage reading, if the adjustment is too low, because the exhaust gas recirculation system does not provide enough exhaust gas in time, detonation will occur when accelerating, if the adjustment is too high, because the exhaust gas recirculation system reacts too fast, the exhaust gas provided is too much, so that the power is reduced;

4. The performance of the coolant temperature sensor is broken: if the coolant temperature sensor fails, the engine will have unstable idling, lack of fire, flameout or increased fuel consumption, etc., a multimeter should be used to check the resistance value of the coolant sensor at various working temperatures according to the manufacturer's regulations.
