Oil Level Indicator Test
- If LOW OIL LEVEL indicator is on and oil level is okay, go to step 3). If LOW OIL LEVEL indicator is inoperative and oil level is low, turn ignition on. Wait 30 seconds and, using Tech 1 scan tester, check for Powertrain Control Module Code 96. If Code 96 is set, see appropriate G - TEST W/CODES article in ENGINE PERFORMANCE.
- If code is not set, disconnect engine oil level sensor connector. Check for battery voltage at engine oil level sensor connector terminal "B" (Brown wire). If battery voltage is present, replace sensor. If battery voltage is not present, check for short to ground in sensor Brown wire. If circuit is okay, replace PCM.
- Turn ignition on. Wait 30 seconds and, using Tech 1 scan tester, check for Powertrain Control Module Code 96. If Code 96 is set, see appropriate G - TEST W/CODES article in ENGINE PERFORMANCE.
- If Code 96 is not set, disconnect engine oil level sensor connector. Check for battery voltage between engine oil level sensor connector terminal "B" (Brown wire) and ground. If battery voltage is not present, check for open circuit or poor connection in Brown wire between PCM terminal No. 27 and oil level sensor terminal "B". If circuit is okay, replace PCM.
- If battery voltage was present, check Black/White wire ground circuit at oil level sensor terminal "A" for an open circuit or poor connection. If ground circuit is okay, replace oil level sensor.
