Low Oil Level Indicator Is Off When Oil Level Is Low

If vehicle has been checked for Diagnostic Trouble Codes (DTCs), go to next step. If vehicle has not been checked for DTCs, see appropriate TESTS W/CODES article in ENGINE PERFORMANCE section:
- TESTS W/CODES - 3.1L
- TESTS W/CODES - 3.8L
If fuel gauge works properly, go to next step. If fuel gauge does not work properly, go to ALL GAUGES & INDICATORS (EXCEPT TURN SIGNALS, HIGH BEAM & SEAT BELT INDICATOR) INOPERATIVE.
Disconnect engine oil level indicator sensor connector. Start engine. If low oil level indicator illuminates, go to next step. If low oil level indicator does not illuminate, go to step 5).
Replace engine oil level indicator sensor. Recheck system operation.
Turn ignition switch to OFF position. Disconnect Powertrain Control Module (PCM) Clear 80-pin connector C2. Turn ignition switch to RUN position. Connect a 3-amp fused jumper wire between PCM harness connector C2, terminal No. 6 (Brown/White wire) and ground. If low oil level indicator illuminates, go to next step. If low oil level indicator does not illuminate, go to step 8).
Turn ignition switch to OFF position. Check for short to ground in circuit No. 1174 (Brown wire) between PCM connector C2 and engine oil level indicator sensor. Repair as necessary and recheck system operation. If circuit is okay, go to next step.
Replace PCM. See procedures in appropriate REMOVE/INSTALL/OVERHAUL article in ENGINE PERFORMANCE section:
- REMOVE/INSTALL/OVERHAUL - 3.1L
- REMOVE/INSTALL/OVERHAUL - 3.8L
Recheck system operation.
Check for poor connection or open in circuit No. 1173 (Brown/White wire) between PCM connector C2 and instrument cluster. Repair as necessary and recheck system operation. If circuit is okay, go to next step.
Repair or replace instrument cluster as necessary. See INSTRUMENT CLUSTER under REMOVAL & INSTALLATION. Recheck system operation.
