Two days ago I was cruising down the highway in the '01 XJ when I saw that the oil pressure needle was pegged at the top side of 80psi. I pulled over, let it idle for a few seconds, didn't notice anything different about the engine, then killed it and checked the oil level to see if anything was unusual. Nothing out of the ordinary so I assumed it was the pressure sensor that was bad.
Two days later I changed out the oil and filter as it was due and I'm taking a hefty road trip this weekend. Nothing unusual in the oil color, no sludge, and the filter seemed fine too. After the oil change it was doing the same thing - sitting on the high side of 80psi.
Is this indicative of a bad oil pressure sensor? Nothing on the FSM shows you how to troubleshoot high pressure, just low pressure. I picked up a new sensor this afternoon for $41 at our local parts store but am looking for some solid support before I throw the parts towards it. My store is good to me and will let me return it if it's unused.
Any ideas? Bad sensor?
