I have a 3800 n/a engine out of a 2001 Pontiac Bonneville. Last night the oil pressure started reading about 110 psi all the time. At the same time it set the check engine light. I haven't had the time to check the codes yet. But I was wondering if there is anything mechanical that could cause high oil pressure. Or am I more than likely just looking at a new sending unit.
Thanks in advance.

Yeah, the check engine light is apparently just a coincidence. It's a code 102. vacuum leak or MAP sensor. I don't see any vacuum leaks or hear any for that matter. So I might try and test the map sensor.
I'm not the one who drives that car, my wife does so I did some further monitoring yesterday. I guess the oil pressure isn't staying at 110. Yesterday when I checked, it appears to be idling at 80 and when driving it hangs between 105 - 110. Like I said I hardly ever drive that card and don't really know what normal is. She just said it's higher than usual.
