Bulb Check

  1. Turn ignition on. Oil pressure light should illuminate. If light does not illuminate, check for faulty oil pressure switch, fuse, indicator bulb, or for open in wiring circuit.
  2. Disconnect oil pressure switch wire connector. See OIL PRESSURE SWITCH LOCATION table. Ground wire connector to engine. If bulb and circuit are okay, indicator light will illuminate. If okay, replace faulty switch.
