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

[McGrant]

Methods to determine the condition of an ABS sensor: 1. Use a fault diagnostic tool to read the fault codes. If there is an issue with the sensor, the ABS computer will display a fault code, and the warning light on the dashboard will illuminate. 2. Measure the resistance of the ABS sensor with a multimeter. The resistance should be between 1000 and 1300 ohms. If it falls outside this range, it indicates a problem with the ABS sensor. Below is some relevant information about ABS sensors: 1. ABS sensors are used in the ABS systems of motor vehicles and serve to monitor vehicle speed. 2. ABS sensors interact with a toothed ring that rotates synchronously with the wheel, generating 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 (ECU), enabling real-time monitoring of the wheel speed.
