Engine Oil Level Sensor

  1. Ensure engine oil level is up to the full mark on oil dipstick. Verify that all fuses and fusible links are okay. Disconnect oil level sensor harness connector.
  2. Turn ignition on, with engine off. Using a jumper wire, jumper sensor harness connector terminals. If LOW OIL LEVEL light turns off, check for faulty connection or faulty oil level sensor. If LOW OIL LEVEL light does not turn off, go to next step.
  3. Connect a test light between battery voltage and oil level sensor harness connector Black/White wire terminal. If test light illuminates, check for open in Brown wire to PCM or faulty PCM connection. If circuit or connection is okay, replace PCM. If test light does not illuminate, check for open in ground circuit Black/White wire.
