"Oil pressure low" flashes on instrument cluster but goes off after a few seconds.

Asked by CMcKinnie Nov 07, 2011 at 07:55 AM about the 2005 Chevrolet Avalanche 1500 LT RWD

Question type: Maintenance & Repair

I had oil sensor replaced, still same message and dinging, in fact it got much worse.  Was told it was the stepper motor on the gauge was the problem.  Replaced the stepper motor and still dinging with message.  Do I need to have the oil pressure pump replaced?  Is it really not getting oil to the motor correctly?

CMcKinnie, I apologize for your frustrations. I don't have an answer to your question; however, here is my advice. Who is working on your vehicle? If it is a GM dealer, I would recommend asking them to involve Technical Assistance. If it is not a GM dealer, I would recommend going into one. Please keep me updated on your situation.

If you have replaced the oil pressure sending unit and are still getting the low oil pressure warning then it is likely the metal screen filter located under the sending unit. If you remove the sending unit and use a dental type hook tool you can remove the screen filter. I did not replace mine and it solved the problem. If you want to replace it the part it'll cost you around $10. Hope this helped.
