I was driving down the road in my 02 tj eariler and all a sudden my oil gauge dropped to 0 so I thought I may have blown a hose so I pulled over. Turns out I didnt have any leaks or blown hoses and my oil is in the safe zone. There is no knocking sound coming from my engine and it runs just fine. Im thinking it may be the oil sensor? Am I correct? suggestions please!
Sounds to me like the oh so common Chrysler oil sending unit. Actually had to replace a couple of these. Dodge Intrepid, Caravan, Spirit, and I think on my new (98) TJ. They are pretty cheap and easy to do, so it's worth a try.
I hope it is your sending unit Benjamen. I would try a mechanical gage (15-20 bucks at auto parts store). I had the same issue on my '01 with the 4.0l. Once I installed the mechanical gage I found that as the motor warmed up I would loose oil pressure, all the way to zero. Long story short, my jeep is at the dealership getting a reman motor installed. Looks like a cracked head allowed coolant to eat up the bearings. I've only had it for 4 months and put on 1100 miles. Gotta love it!
