Did you perform the IPC Diagnostic System Check?

Go to Step 2

Go to Diagnostic System Check - Instrument Cluster

Verify the low engine oil level indicator is always on. Does the system operate normally?

Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems

Go to Step 3

1. Turn the ignition OFF.
2. Disconnect the engine oil level sensor.
3. Connect a fused jumper wire between the oil level sensor signal circuit and a good ground.
4. Turn the ignition ON, with the engine OFF.

Does the low engine oil level indicator illuminate?
