DTC P0500: Vehicle Speed Sensor (VSS) MALFUNCTIOM (A/T)
- Ensure ignition is off. Disconnect VSS harness connector. Using ohmmeter, measure resistance between VSS component terminals. Resistance should be 100-300 ohms. Measure resistance between ground and each component terminal. Resistance should be 1 megohm or greater. If resistances are as specified, go to next step. If resistances are not as specified, replace VSS.
- Remove VSS and visually inspect sensor and countershaft gear for contamination and/or damage. Repair as needed. If no damage is present, inspect both circuits between VSS and PCM for open or short. Repair as needed. If both circuits are okay, replace PCM.
