High oil pressure

Hey guys. Last night on my way home from work, I noticed that my oil pressure guage was maxed out on 80. I have a 1999 Wrangler Sport and it's running just fine. I'm pretty sure it's the oil pressure sensor gone bad, but I'd like to hear some feedback from you guys. Thanks!

I also have a '99 sport and mine is also always pegged at 80. Been that way for a year, runs like a champ, I just havent gotten around to changing the sending unit. But I will soon.

Try the simple/free fixes first. The sender's connector may just be full of dirt or oil. Disconnect the connector and flush it out with wd-40 then reconnect it. If that doesn't fix it, then it's time for a new sender.

^ thanks Jerry. A recent thread said it can be tricky getting the connector off. Something about the oil filter in the way or needing a deep socket? I was going to do it at my next oil change. Would this make it easier ?

The oil filter is not in the way of the connector. Take a look, it's not very difficult to get the connector disconnected

It's one of those rare quick and easy repairs.

Listen to the Jerry! Lol, thanks for the input y'all. By the way, I had an easy time putting on my new frameless soft top last night due to the fact that it was a perfect 76 degrees outside. I love Texas!
