Oil Pressure Gauge

The oil pressure gauge on my 02 TJ 4.0 is pegged at 80 and its running fine. It just started this. I'm assuming its a bad sensor or something. does anyone have any ideas?

Most likely its the oil sending switch, but one from the dealer. They are more reliable than those from auto parts stores. (Made in China)

Takes five minutes and one wrench to swap out the sending unit. $26 at autozone. Did mine a few hours ago. Mine was failing low though, not high. Try to put some newspaper under you because a little bit of oil will drip out
