Speed Sensors

TESTING

1. Inspect the sensor. Disconnect the speed sensor wiring.
2. Measure the resistance between terminals. Standard resistance is:
   • Front — 0.6–1.8 kilometers
   • 1.05–1.45 kilometers

     Fig. 2: Rear speed sensor connector terminal locations

3. If the resistance value is not within specifications, replace the speed sensor.

   Fig. 3: Using an ohmmeter, check for continuity between each terminal and body, if present, replace the sensor

4. Check that there is no continuity between each terminal and the sensor body.
5. If there is continuity, replace the sensor.
6. Connect the speed sensor wiring.
