Oil Pressure Switch Inspection
- Verify that the oil pressure warning light illuminates as the ignition switch is at ON position.
- Verify that the oil pressure warning light goes off when the engine is started.
- If the oil pressure warning light does not illuminate or remains illuminated, inspect the oil pressure warning light bulb and related wiring harness.
- If the oil pressure warning light bulb and related wiring harness are normal, inspect the oil pressure. (See OIL PRESSURE INSPECTION [AJ] .)
- If the oil pressure is normal, replace the oil pressure switch.
