I seem to be having the same negative oil pressure problem someone else posted. I haven't tried a new sensor yet but have a few questions about sensors. First is kind of a no brainer, should oil be leaking into where the wire connects to the sending unit? I assume this sensor is broken and is what is causing my negative oil pressure readings. The second question I have is about another sensor I know is broken but do not know what it is called. I have a 2.5 liter in a 1992 wrangler and there is a sensor on the rear driver side of the head which attaches next to the valve cover. Thanks for any feedback.
