Speed Sensor Test
- Disconnect connector to speed sensor, and connect an ohmmeter between wire connector terminals (Dk. Green/White wire and Black wire) at speed sensor end. A reading of approximately 180-250 ohms should be obtained. A reading of 0 ohms indicates a shorted coil and a maximum reading indicates an open coil. Replace sensor in either case.
- If ohmmeter reads 180 to 250 ohms and speedometer operates properly, speed sensor is probably good. A good speed sensor can be substituted in place of existing sensor to check proper operation.
