Oil pressure

Asked by Tayy Feb 11, 2016 at 02:39 PM about the 2008 Chevrolet Tahoe LT 4WD

Question type: Maintenance & Repair

I have an 08 tahoe that I would like to
know whats causing the oil pressure to be
low.  When the truck is parked and not
running the oil pressure gauge stays at 20.  
I drive it for about 15 minutes and the
gause drops to halfway of 20.  When
accelerated it raises to about half way.  But
when idling it drops again.

I literally fixed this problem on my Tahoe 09 Tahoe yesterday, I first thought it was the Oil Pressure Sensor but after reading a couple different forums it seems everyone has a different solution, you can start by getting a fresh oil change and engine flush, second thing would be the Oil Pressure Sensor the part is available on amazon ACDelco 213-4411 GM Original, there is a video on YouTube where they walk you step by step on how to change it out its fairly simple and takes about 30 minutes.
