I have a 2000 WJ 4.0 with a weird oil pressure indication on the guage. It started once in a while pegging out at 80 psi and after a restart, would read normal. No it's pegged all the time. I figured I'd change it. Okay, Where it frog is it? It's not next to the oil filter where it used to be and the oil filter screws directly into the block, not into an adapter like they used to. I've had my oil changes done at Valvoline because I trust them. I used to work there and the one store manager knows me well.

Where did Jeep hide the oil pressure sensor?

 

Come on, guys. Someone must have looked for it before. It's NOT by the oil filter. My oil filter screws directly into the block above the oil pan, not into the adapter that is usually on the 4.0s. I've looked everywhere on the passenger's side of the engine and I don't see it. Please don't tell me they moved it to the back of the block!

behind the oil filter on the block where it always has been on the 4.0

 

Okay! I found it! It was hiding under a wire loom. On my 97 ZJ, it was right next to the oil filter. That one had an adapter who's O-ring used to leak. I thought I was going bonkers cause I couldn't find it. Thanks, guys. It is leaking, so I'll change it soon.
