The symptoms of car speed sensor damage include: engine instability when idling; instant parking or shutdown when the vehicle starts or slows down during driving; engine acceleration performance declines; instrument car The speed display is uneven; the engine fault indicator light is on.
The symptoms of the broken speed sensor of the car are as follows: the engine is unstable when idling; when the vehicle starts or slows down and stops while driving, there is an instant pause or shutdown phenomenon; the acceleration performance of the engine decreases; the speed display on the instrument is deviated; the engine fault light is on.
When the vehicle slows down and stops while starting or driving, there is a momentary pause or shutdown; the acceleration performance of the engine decreases;The speed display on the instrument is deviated; the engine fault light is on; the throttle position sensor is broken: if the throttle position sensor is unbalanced, the correct ignition advance angle and air-fuel ratio of the mixture cannot be guaranteed.
Once the sensor is lightly damaged, it will cause the engine to fail to start or the performance will decline, which will lead to serious failure of the car and even endanger personal safety. Fault phenomenon: Most cars cannot be started because the PCM does not receive the engine speed signal and does not provide fuel injection and high-pressure fire.
can't pass The repair method can only be replaced by the speed sensor. The speed sensor is an indirect device, which mainly tests the speed of the vehicle. The main working principle is to use the magneto-sensitive resistor as the induction original.
Repair can't solve the problem, so the speed sensor can only be replaced. The speed sensor is an indirect device that mainly detects the speed of the vehicle. Its main working principle is to use magnetoresistance as a sensing element. Motor vehicle speed sensor is a new type of speed sensor generated by magnetoresistance effect induction.Its core component is magnetic resistance.
When the speed sensor fails, it needs to be repaired or replaced immediately. A speed sensor is a sensor that converts the rotational speed of a rotating object into power output. The speed sensor is an indirect measuring device, which can be manufactured by mechanical, electrical, magnetic, optical and hybrid methods.
1. Once the sensor is lightly damaged, the engine will not be able to start or the performance will decline, which will seriously lead to serious failures of the car or even Endanger personal safety. Fault phenomenon: Most cars cannot be started because the PCM does not receive the engine speed signal and does not provide fuel injection and high-pressure fire.
2. The engine is unstable when idling; when the vehicle starts or slows down while driving, there is an instantaneous pause or shutdown; the acceleration performance of the engine decreases; the speed display on the instrument is deviated. The engine fault light is on.
3. The damage symptoms of the car speed sensor are: engine instability when idling; instant stop or shutdown when the vehicle starts or slows down during driving; engine acceleration performance declines; uneven instrument speed display; engine fault indicator light on.
1. The signal wheel is designed as a wheel with many tooth segments, which is divided into 60 tooth segments.Whenever the signal rotates through the sensor, an AC voltage is generated, and its frequency changes with the speed. The frequency is the speed of rotation; in order to identify the position of the crankshaft, the signal wheel has a gap between the two tooth segments.
2. If the new sensor of the Jetta still doesn't work, you need to check the line. If there is no problem with the line, it may be that the engine computer is damaged. Because the Jetta car has been used for a long time, it is easy to block the drainage hole with dirt, because the computer is under the wiper, and the rain is easy to soak the computer, resulting in damage to the computer.
3. When the resistance value exceeds the specified range, it means that the sensor has been damaged and the speed sensor needs to be replaced. If the resistance value is within the specified range, the following exclusion methods are required for the wire between the sensor and the engine electronic control unit: short circuit to the ground, short circuit to the positive, broken circuit, or the wire between the connection.
4. If it is only the crankshaft speed sensor of the engine --- the fault phenomenon -- most cars cannot be started, because the PCM does not receive the engine speed signal and does not provide fuel injection and high-pressure fire. Exclusion method -- using an oscilloscope for waveform detection is the most direct and effective.
5. Use an oscilloscope to test the waveform. If there is a problem with the speed sensor, there will be no fire and fuel injection signal.

4. Engine speed sensor signal failure. Check whether there is any abnormal sound, and learn to distinguish the problem of abnormal car abnormal noise that belongs to reasonable noise. It is difficult for ordinary car owners to distinguish which are faulty abnormal noise and which are reasonable abnormal noise.When I went to the repair shop to test the abnormal sound of the vehicles, only nearly 20% of the vehicles really had problems.
