Vehicle Speed Sensor (VSS)

  1. Faults in VSS or circuit should set service code. See QUICK TEST in TESTS W/CODES - EEC-IV article in the ENGINE PERFORMANCE section. Disconnect VSS electrical connector if service code has not been set.
  2. Using DVOM, measure resistance across sensor terminals. Resistance should be 190-250 ohms. Replace sensor if not within specification. If sensor is within specification, see CIRCUIT TEST DP in TESTS W/CODES - EEC-IV article in the ENGINE PERFORMANCE section for additional circuit testing.
