Oil Pressure Warning Lamp/Indicator: Testing and Inspection

The low oil pressure warning lamp will illuminate when the ignition switch is turned to the ON position without engine running. The lamp also illuminates if the engine oil pressure drops below a safe oil pressure level.

Oil Pressure Switch:

To test the system, turn the ignition switch to the ON position. If the lamp fails to light, inspect for a broken or disconnected wire at the oil pressure switch, located at the front of the engine. If the wire at the connector checks good, pull the connector loose from the switch and with a jumper wire, ground the connector to the engine. With the ignition switch turned to the ON position, check the warning lamp. If the lamp still fails to light, inspect for a burned out lamp or disconnected socket in the cluster.
