absThe sensor is applied to the ABS of a motor vehicle, and its function is to monitor the speed of the vehicle. The abs sensor outputs a set of quasi-sinusoidal alternating current signals, whose frequency and amplitude are related to the wheel speed, through the action of the ring gear that rotates synchronously with the wheels. The output signal will be transmitted to the ABS electronic control unit.YuanInside the ECU, real-time monitoring of wheel speed can be realized. The quality of the abs sensor determines the sensitivity of the ABS system, which is related to driving safety. How to judge whether the abs sensor is good or bad?

absHow to judge the quality of the sensor

1. Read with a fault diagnosis instrumenterror code: If there is a problem with the sensor, a fault code appears in the ABS computer, and the fault light on the meter will also light up.

2. Use a multimeter to measure the resistance of the abs sensor: the general resistance value is between 1000-1300Ω, if it does not meet this range, it indicates that there is a problem with the abs sensor.

If the abs sensor is broken, it will cause the abs system to fail. At this time, the abs fault light on the car dashboard will light up. If during emergency braking, the wheels will lock up, causing the wheels to slip out of control. Once the abs sensor is damaged, it should be repaired or replaced in the repair shop in time, so that the driving is safer and more secure.
