Did you perform the Diagnostic System Check - Vehicle?

Go to Step 2

Go to Diagnostic System Check - Vehicle in Vehicle DTC Information

1. Install a scan tool.
2. Turn ON the ignition, with the engine OFF.
3. With a scan tool, observe the Engine Oil Level Switch parameter in the powertrain control module (PCM) Engine Data  2 data list.

Does the Engine Oil Level Switch parameter display Ok?

Go to Step 3

Go to Step 4

Does the driver information center (DIC) display Engine Oil Low - Check Level?

Go to Step 11

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

1. Turn OFF the ignition.
2. Disconnect the engine oil level switch.
3. Connect a fused jumper between the oil level switch signal circuit and a good ground.
4. Turn ON the ignition, with the engine OFF.
5. With the scan tool, observe the Engine Oil Level Switch parameter.

Does the Engine Oil Level Switch parameter display Ok?

Go to Step 6

Go to Step 5

Test the oil level switch signal circuit for an open or for high resistance. Refer to Circuit Testing and to Wiring Repairs in Wiring Systems.

Did you find and correct the condition?

Go to Step 12

Go to Step 8
