GM PID LIST OIL PRESSURE PROFESSIONAL

GM bulletins are intended for use by professional technicians, NOT a 'do-it-yourselfer'. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed. Please follow this diagnostic or repair process thoroughly and complete each step. Notice: If an engine noise is noticed after replacing the oil pump, follow the SI diagnosis and repair the engine as necessary. If SI diagnosis isolates low mechanical oil pressure at the oil filter housing and oil pressure sensor, replace the oil pump, flush the oil cooler lines (if equipped), clean the inside of the oil pan, change the oil and filter, and re-evaluate the concern.

In some instances, this may occur intermittently if the valve frees up when the engine cools down. Some customers may complain of low oil pressure, no oil pressure, and/or engine noise, which may be the result of a sticking oil pump pressure relief valve. The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
