How to Test if an ABS Sensor is Good or Bad?
1 Answers
ABS sensor testing methods are: 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. Additional information: ABS sensors are used in automotive ABS systems to monitor vehicle speed. The ABS sensor interacts with a toothed ring that rotates synchronously with the wheel, generating a set of quasi-sinusoidal AC signals whose frequency and amplitude are related to wheel speed. This output signal is transmitted to the ABS electronic control unit (ECU) to enable real-time monitoring of wheel speed.
