Hi Jeremy. Nice to see you today! I'm sorry to hear you are having this problem. I know this can be frustrating. Jeremy, are there any unusual engine noises like ticking or knocking when the warning is set?

no it's quite

ok, Perfect. Thank-you, Jeremy. Please give me one moment to type out some information for you. Sit tight one minute... I'll be right back! Thanks for holding, Jeremy. As long as there are no unusual engine noising, like ticking or knocking, then from what you are describing here, this sounds like this may be the case of a failing Oil Pressure Sensor. These are very common fail items on these vehicles. Over time, the internal workings of the sensor tend to fail, and the sensor has a hard time reading correct pressure. The sensor is located on the front of the engine, between the [alternator](/topics-alternator-gmc/) and the oil filter. There is a metal shield covering it. This will need to be removed to gain access to the sensor. Inspect the electrical connector and wire harness for any loose, broken or damaged wires. If no problems are found, I would recommend the 'actual' oil pressure be tested with the use of a pressure testing tool, just to ensure no internal problems like a failing oil pump. If actual pressure checks good, replacing the sensor should solve the problem.

okay I'm taking to a garage Monday it's under warranty just didn't know if I could drive it till thenthe oil level is good and the oil looks good to

Yes. Perfectly safe to drive. The oil pressure sensor is for driver informational purposes only. It does not play a role in engine performance or operation.

could the oil pump be bad

It 'could' be... but this usually presents with ticking or knocking. So not very likely. But, as I mentioned above, always a good idea to have the actual oil pressure tested to rule this out.

as long as their is no knocking then it's fine to drive,and I'm taking it Monday

That's correct, Jeremy.

okay thank you

You're welcome, Jeremy! Glad I could be of some help today! I hope everything works out well for you! Have a great day! Thank you for choosing Just Answer for your questions!
