Oil Pressure Gauge Always Reads Low
- If diagnostic system check has been performed, go to next step. If diagnostic system check has not been performed, perform INSTRUMENT CLUSTER DIAGNOSTIC SYSTEM CHECK under SELF-DIAGNOSTIC SYSTEM.
- Start engine and observe engine oil pressure gauge. If oil pressure gauge does not indicate an acceptable level, go to next step. If oil pressure gauge indicates an acceptable level, problem may be intermittent. Try to recreate fault by wiggling wiring and connectors. Check for faulty connections at all connectors that may be causing intermittent condition. See WIRING DIAGRAMS .
- Turn ignition off. Disconnect oil pressure sensor connector. Turn ignition on and observe oil pressure gauge. If oil pressure gauge indicates high pressure, go to next step. If oil pressure gauge does not indicate high pressure, go to step 5 .
- Replace oil pressure sensor. Recheck system operation.
- Check for short to ground in Tan wire between oil pressure sensor and instrument cluster. Repair wiring as necessary. Recheck system operation. If Tan wire is okay, go to next step.
- Replace instrument cluster. See INSTRUMENT CLUSTER under REMOVAL & INSTALLATION. Check system operation.
