Hello
I have 07 suburban 1500 w 5.3l right at 195k.
On our last trip. The CEL came on.
When i got home I scanned it with my autel ms909 . I got oil pressure switch out of range.
I replaced the oil pressure switch and the filter. But still getting only a max of 40psi.
What could cause this ? Oil pump, pickup tube seal?
How can I verify if it's either?
Thank you
