Oil Pressure Indicator

WARNING: This page is about a different car, the 1995 Ford Mustang. However, it is still accessible from the selected car via links, so may be relevant.
  1. Turn ignition on. If indicator light is not on, ground oil pressure switch connector. If light fails to come on with lead grounded, inspect for burned out bulb and/or open in wiring.
  2. If light stays on with engine running, and manual test gauge indicates engine has good oil pressure, unplug oil pressure switch connector. If light goes out, replace oil pressure switch. If light stays on with switch disconnected, inspect for short in wiring between oil pressure switch and indicator bulb. See appropriate wiring diagram under WIRING DIAGRAMS.
