ABS is a very important system in a car. Its function is to prevent the wheels from locking up when braking suddenly or on icy and snowy roads, and to prevent the vehicle from losing control.And there is one on the ABS systemabsThe sensor is used to monitor the speed of the vehicle. It transmits the speed information to the ABS system so that the ABS can work normally. If the abs sensor is broken, it will cause the abs system to fail. When the car brakes in an emergency, the wheels will lock up, causing the wheels to slip out of control. Therefore, the abs sensor is also very important. How to judge that the abs sensor is broken? Let's learn about it together.
How to judge absSensor is broken
1. Use the reading fault diagnosis instrumenterror code: If there is a problem with the sensor, there is a fault code in the ABS computer, and the fault light on the meter will also be on;
2. On-site brake detection: In a place with good roads and wide areas, speed up the car to above 60, preferably not more than 80, and then step on the brakes to the end. If the wheels are locked and the brakes do not feel frustrated, the abs is invalid. , Generally caused by damage to the abs sensor;
3. Use a multimeter to measure the voltage of the abs sensor/resistance: Rotate the wheel at a speed of 1r/s, the output voltage of the front wheel should be 790-1140mv, the rear wheel should be higher than 650mv, if it does not meet this range, thenIndicates that there is a problem with the abs sensor; and the abs sensorresistancegenerallyBetween 1000-1300Ω, if it does not meet this range, it indicates that there is a problem with the abs sensor.
