Oil Pressure Gauge
2000 Cherokee Sport.4L,4WD 80,000 miles.
Every now and then my oil gauge pegs at 80 when I start the vehicle.If it
pegs when I start the car it will remain there for the entire trip .If at
startup it works correctly it will remain working the entire trip.
All other gauges work fine.I have replaced the sender and checked voltage at
the sender.The sensor shares a ground with other devices that work properly.
My question is does the pegged gauge indicate that all 5Volts from
the PCM is passing thru or could there be no power getting to the gauge
(magnet) allowing it to peg with less than 5Volts?
P.S. Already tried hitting dash/shaking wires.
Thanks

Re: Oil Pressure Gauge
You ignition switch may be getting stuck in the test mode that all
cars go through on start. Or you have a short to ground between the
gauge and sending unit, near the oil filter.

Re: Oil Pressure Gauge
could be the sending unit is starting to go u/s. Mine has been acting up
for the past couple of years.
