Oil Pressure Low Stop Engine

I was having the same issue in my 2013 Acadia. Took it to the dealership and I have to replace the oil pump. Very expensive! But it has to be done. When they replace the oil pump they have to redo the timing and everything so if you are having any issues I would take it in to a dealership that knows the vehicle and have them check. I was getting the low oil pressure turn off engine message even after oil change. There wasn't a code to run since it would happen whenever.

"Hi @ gail.wadley,

You may have a faulty oil pump.

Here's a link that may help.

Either that or get a mechanic to check it out."

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

I replaced my sending unit - 3 weeks ago. I drive 150 + miles a day and the light has not come back on. I posted on a forum acadia page, the advice I received was to try the sensor first. The year make and model of mine were notorius to have issues where the sensor stopped sending communicating with the ecm.
