Switch Check
Disconnect oil pressure switch wire connector. See OIL PRESSURE SWITCH LOCATION table. Using ohmmeter, measure resistance between switch terminal and ground. Continuity should exist with engine stopped. No continuity should be present when there is oil pressure (engine running). Replace as required.
