The abs sensor is applied to the ABS (Anti-lock Braking System) of the motor vehicle. In the ABS system, the speed of the vehicle is mostly monitored by an inductive sensor. The abs sensor outputs a set of standards through the action of the ring gear rotating synchronously with the wheel. Sinusoidal AC signal whose frequency and amplitude are related to wheel speed. The output signal is transmitted to the ABS electronic control unit (ECU) for real-time monitoring of the wheel speed.

Read the fault code with a car-specific device.

Now the car has an OBD diagnostic interface. After the ABS lamp is lit, it is necessary to read the fault code with the device and perform maintenance according to the fault code. Otherwise, there is no direction. For example, the fault code is C0034: the left rear wheel speed sensor is open or shorted. malfunction.

Visually inspect the sensor.

After reading the fault code, you can check the corresponding sensor first. For example, you can first check whether the left and right wheel speed sensors are broken or worn, and whether the sensor harness is disconnected is simple but necessary.

Measure the voltage at the sensor plug.

In most cases, the sensor is faulty. When no obvious problem is observed in the sensor, the sensor harness can be measured with a multimeter. The ABS wheel speed sensor is two-wire type, one signal, one grounding, when the line appears. When the circuit is open, the complete data cannot be read.
