Checking The Wiring

Check the signal cable between engine control module (ECM) terminal #A40 and oil level sensor terminal #1. Check for a short-circuit to ground.

HINT: With the ignition on, the voltage between terminals #2 and #3 must be 5 V, with the reading taken at the oil level sensor connector. 

Try a new oil level sensor if no fault is found and the fault is permanent.

Remedy as necessary.
