Fig. Fig. 1: Typical Vehicle Speed Sensor (VSS) with connector and driven gear

The Vehicle Speed Sensor (VSS) is a magnetic pick-up sensor that sends a signal to the Powertrain Control Module (PCM) and the speedometer. The sensor measures the rotation of the output shaft on the transaxle and sends an AC voltage signal to the PCM which determines the corresponding vehicle speed.

TESTING



  1. Disconnect the negative battery cable.
  2.  
  3. Disengage the wiring harness connector from the VSS.
  4.  
  5. Using a Digital Volt-Ohmmeter (DVOM), measure the resistance (ohmmeter function) between the sensor terminals. If the resistance is 190-250 ohms, the sensor is okay.

  2.  
  3. Detach the three-prong connector from the Vehicle Speed Sensor (VSS).
  4.
