Condition
Some customers may comment on a low oil level indicator lamp on and/or engine oil leak. Upon further investigation, the technician may find that the oil leak is at the oil pressure sensor that is threaded into the valve lifter oil manifold (VLOM) assembly and/or engine valley cover.
Correction
If the engine oil leak was found to be at the engine oil pressure sensor, then remove the oil pressure sensor and reseal with a pipe sealant with Teflon or equivalent, P/N 12346004 (in Canada, P/N 10953480). Refer to Engine Oil Pressure Sensor and/or Switch Replacement in SI.
