Print

Operation



A 5 volt voltage is applied to the Vehicle Speed Sensor (VSS) output terminal from the ECM/PCM. The sensor generates a pulse signal when the output terminal is opened and grounded.

Testing



  1. Disconnect the sensor connector and measure at the harness side.
  2.  
  3. Turn the ignition switch to "ON" position.
  4.  
  5. Measure the voltage between terminal 86 (M/T) or terminal 80 (A/T) and ground. Voltage should be between 8 and 12 volts.
  6.  
  7. Turn the ignition switch to "LOCK" (OFF) position.
  8.  
  9. If any check above does not meet the specifications, check connectors and wiring between the sensor and ECM/PCM. If ok, replace ECM/PCM.
  10.  
  11. If checks above meet the specifications, replace the VSS.
  12.
