Vehicle Speed Sensor: Testing and Inspection

On-Vehicle Inspection
1. Hoist vehicle.
2. Release parking brake lever, set transmission in neutral and transfer in "2H".
3. Remove ECM (PCM) cover.
4. Connector voltmeter between VSS terminal of ECM (PCM) connector and body ground.




5. Turn ignition switch ON and turn rear right tire slowly with rear left tire locked.
Voltmeter should indicate deflection between 0 - 1 V and 8 - 14 V a few times while tire is turned one revolution.
If check result is not satisfactory, proceed to Step 2 of "DTC P0500: Vehicle Speed Sensor Malfunction".
