How to Determine if an ABS Sensor is Good or Bad?

[Elliot]

The methods to determine if an ABS sensor is good or bad are: 1. Use a fault diagnostic tool to read the fault codes. If there is an issue with the sensor, a fault code will appear in the ABS computer, and the fault light on the dashboard will also illuminate; 2. Measure the resistance of the ABS sensor with a multimeter. A normal resistance value should be between 1000 and 1300 ohms. The ABS sensor is used in the anti-lock braking system of motor vehicles. It monitors the vehicle speed using an inductive sensor. The ABS sensor interacts with a toothed ring that rotates synchronously with the wheel, outputting a set of quasi-sinusoidal alternating current signals. The frequency and amplitude of these signals are related to the wheel speed. This output signal is transmitted to the ABS electronic control unit to enable real-time monitoring of the wheel speed.
