I don't know the range but I can tell you mine appears to fall in it and my VIN is 7470. This past weekend I noticed my oil pressure dropped to just above the the zero mark on the oil pressure gauge on the 4-pack while idling. At cruising speed it still only registers ~ 25 pounds. I carried it by the dealer today and they said did you get a low oil light come on and I replied no and he said it is probably nothing then. I told them it is either low pressure or a bad gauge, I don't know which it is but they are going to fix it.

In deed. Its on the lift and HOPEFULLY will be finished up today!!


We talked to a GM tech and he said a TEMPORARY FIX: Fire the Car up and DEAD REV it to get the Oil Pressure to UN-Stick the plunger. If the oil pressure comes back, you should drive the car Home, or to your local dealer as it will probably/WILL get stuck again.

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
<A href="#ss1-2435251">Condition/Concern:

Some customers may complain of a low oil pressure message/light on the dash and a technician may find a P0521 DTC in the ECM.
<A href="#ss2-2435251">Recommendation/Instructions:

If this concern is encountered, follow SI diagnosis. If it indicates that the Tech 2 oil pressure parameter is low but proper oil pressure is present at the oil filter housing, inspect the Valve Lifter Oil Filter for debris/sludge that could be restricting oil flow to the oil pressure sensor before replacing any parts.
Follow the Valve Lifter Oil Filter Removal and Installation Procedure to remove the filter for inspection. If the filter is plugged, it can normally be cleaned with brake/contact cleaner and light shop air. If it cannot be cleaned for some reason, replace it using the part number listed in the parts catalog. Do not replace the complete Valve Lifter Oil Manifold just because the filter is plugged.
#452 - Valve Lifter Oil Filter




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.
