Oil Pressure Warning Lamp/Indicator: Testing and Inspection

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

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 on the rear 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 in the cluster. Refer to the proper Body Diagnostic Procedures manual for more in depth testing.
