Vehicle Speed Sensor

  1. Disconnect vehicle speed sensor harness connector, and remove sensor. DO NOT lose rubber seal on sensor harness connector. Using an analog ohmmeter, connect ohmmeter leads across sensor terminals.
  2. Slowly rotate sensor shaft while observing ohmmeter. Ohmmeter needle should jump between zero and infinity readings 8 times for each complete sensor shaft revolution. If sensor does not operate as specified, replace sensor.
NOTE: Ensure rubber seal on vehicle speed sensor harness connector is not missing or damaged. Water and road dirt in sensor connection will cause a false trouble code to be set.
