The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

Condition/Concern:

Some owners may comment that the Engine Oil Pressure MIL is illuminated and upon inspection technicians may find a stored DTC P0522. This concern could be caused by a damaged circuit for the EOP sensor at X108. The 5 volt reference circuit 2705 is a very small gage circuit with extra length between the back of the connector and the conduit clip making it prone to damage.

Recommendation/Instructions:

Repair as necessary.

Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
