WARNING: This page is about a different car, the 1997 Isuzu Trooper. However, it is still accessible from the selected car via links, so may be relevant.
- Start engine. Disconnect oil pressure switch lead, and ground lead. Oil pressure warning light should come on. If warning light does not come on, repair open circuit.
- If warning light comes on, check continuity between oil pressure switch terminal and ground with engine at idle. Replace oil pressure switch if continuity does not exist.
