Installed a new oil pressure sensor in my 01 Wrangler. The oil pressure was originally reading high (80). Found through this forum that this is a common issue and was a quick fix. Locating the sensor was easy. Do not waste money on the special sensor socket, it usually doesn't fit if the original sensor is in, instead just use a 1 1/16" deep socket. It is a tight fit with the ratchet and socket, some swear words help. Now project Chiqui reads the oil correctly at 40. Once again, thanks to everyone on this forum for all the extra knowledge.
