Oil Pressure Low Stop Engine

"Naif, Heather M , It very well could be a bad oil pressure sending unit/sensor, but better to be safe then sorry and have it checked out right away. If you hear any noises from engine knocking/ticking or if engine is not performing as usual discontinue starting/driving vehicle as there could be a major problem internally of engine. If driveable have the vehicle scanned for trouble codes to see if a failing oil pressure sensor is the issue and have it replaced. Some of the auto parts suppliers offer free code reading like Pepboys, Nappa, Advanced auto parts,etc and some of the guys are very knowledgeable and may have seen the issue often and put you on the right track.

If it is not the oil pressure sensor it could be a more serious problem like a failing oil pump, plugged/ pick up tube fell off, oil filter plugged, etc etc., a good technician will put a manual oil pressure gage on the engine to verify low oil pressure and then have to diagnose why. Good luck. I hope this helped you out, if so let me know by pressing the helpful button."

Hi @ gail.wadley,

I have it in an 08. Drive 10 miles, stop and it goes on at low rpms. Put it in neutral and rev above 1000 rpm and it turns off. Right now rpms control it. For all I know a failing oil pump doesn't circulate oil at low rpms?

Camshaft sensor accuater the GMC ACADIA has 4 of them one for each cam so you half to see what code its reading out to know which one it is!! Mine is doing same thing guy told me it was timing chain & I need a new timing kit supposed to have something to do with oil pump
