DTC P0500 - Vehicle Speed Sensor (VSS)

  1. Check Input Signal Circuit  - Turn ignition off. Disconnect ECM harness connector and combination meter harness connector. See Figure. Using an ohmmeter, check continuity between ECM harness connector terminal No. 26 combination meter harness connector terminal No. 23 for models with tachometer or terminal No. 21 for models without tachometer. See Fig 1. If no continuity exists, repair open in Purple/Red wire. If continuity exists, go to next step.
  2. Check Speedometer Operation  - If speedometer does not function, disconnect VSS harness connector. Remove VSS from transaxle. Check resistance between VSS connector terminals. Replace VSS if resistance is not 250 ohms. If resistance is 250 ohms, go to next step.
  3. Set voltmeter on AC scale. Connect voltmeter to VSS connector terminals. Turn VSS pinion gear to generate voltage. Voltage should generate to about 0.5 volt. If resistance and voltage are not correct, replace vehicle speed sensor. If VSS unit is okay, check ECM connector terminals for corrosion or damage. Repair as necessary and retest system.
