The oil pressure gauge recently went to 80 one morning and has consistently stayed there. I had my oil changed to see if this would help but hasn't. The vehicle is running fine, but the pressure is at 80??? This has never happened, has always been around 40-50, then shot up to 80 and stayed. From what I have heard that the sender unit failed???? If this sounds right, where is this unit located and is it easy to replace instead of going to a dealer

Thanks....

The sending unit is adjacent to the oil filter adapter...look for a sensor
with 2 wires on or near the oil filter adapter. Most likely you have a bad
sensor, but to double check plug a mechanical test gauge into the port and
check the pressure.

But first put the sensor wire back on, it fell off. :)

on the I6 it's down on the block just above the oil filter.

Could be the sensor, it's easy to replace with simple hand tools
and NAPA has the part.

It is easy to change,and I got one aftermarket.
With the engine off and the key in the on position does it still peg?
If you disconnect the sensor wire and do this again does it peg or stay
at -0-.
My 00 Sport sometimes pegs and will remain there for the drive cycle.I
changed the sensor,it was not the cause on mine.
When mine pegs I turn the key to the acc. position then off 2 or 3 times and
then it works again for a while,some kind if short.

Please post how you corrected yours. Thanks
