Oil Pressure Light Bulb Check
- Turn ignition on. Oil pressure light should come on. If light does not come on, check for faulty oil pressure switch, indicator bulb, or open in wiring circuit.
- Disconnect oil pressure switch connector. Oil pressure switch is located on lower rear center of engine, near oil filter. Ground oil pressure switch wire connector to engine. If bulb and circuit are okay, indicator light will illuminate. If light illuminates, replace faulty oil pressure switch.
