Oil Pressure Switch Test

Disconnect oil pressure switch connector (Yellow/Red wire), located above oil filter. Check continuity between ground and oil pressure switch terminal (component side). Continuity should exist when engine is stopped. Continuity should not exist when engine is running. If continuity is as specified, oil pressure switch is okay. If continuity is not as specified, check engine oil level and oil pressure. See OIL PRESSURE SPECIFICATIONS  . If oil level and oil pressure are okay, replace oil pressure switch.
