90

Asked by Archevy Mar 19, 2016 at 06:27 AM about the 2007 GMC Yukon SLE1

Question type: Maintenance & Repair

I have a 07 GMC Yukon that always ran fine today I
had been driving for about a hour when the oil
pressure went up to 65 it has always ran 40-50
when driving and it always idles around 20-30 also
when I turn the engine off and turn key back on oil
pressure gauge shows 20 without the engine
running I was wondering what would be the
problem and if it's leading to something else thank
you for your help.

Yes that is a must on cleaning the screen under the oil pressure sending unit. 2007 is when GM started putting that in and do get clogged up causing a false oil pressure reading. Still replace the oil sending unit.

I agree with Rowefast, replace the sender and clean the screen.
