So I purchased a '00 Sport (4.0, 5spd) about a month back, first time jeep owner. When I purchased it I noticed the oil pressure gauge only reads 10ish psi at all times. Cold start, warm start, cold day, hot day, regardless of RPM...10psi. After doing some research I saw the issues with the sensor working fine for a bit then just dropping to 0. I also found that my gauge should still be an actual functioning gauge (i.e. the gauge should move depending on the above variables), as they didn't change the PCM programing until '02ish to make it a "dummy gauge". I know the wiring to the sensor is good as if I unplug it, it reads 0 and the "check gauges" light comes on. Before throwing money at it, I figured I'd ask here first and see if anyone had this issue, or may have some suggestions. I think I'm going to pull the sensor, give it a good spray of parts cleaner and see what that yields. Thanks.
