Disconnect the sensor at the wheel and use a digital multimeter to check the resistance of the sensor. Check the manufacturer’s specs to see the acceptable range. If you do not have access to that data, then check another wheel sensor and compare the readings. They should be close to one another. Then, change your meter to read AC volts. Spin the wheel and you should see approximately 1 volt. Do the same at another wheel to compare the readings. Before you condemn the sensor, check the reluctor ring for missing or cracked teeth (also known as the tone ring). Also, check the sensor and remove any metal filings, dirt, or grease that may have accumulated on the sensor surface.
