I have a 2006 Jeep Grand Cherokee
85 k miles
My temp display
is stuck on -40 degrees.
I ordered a new sensor installed and same problem.
Some test I did
I checked the connector for a short nothing
I checked both sides of connector left side has 5 volts and right side has continuity to ground.
I also put a short across the connector and the display showed 131 degrees.
So i think the connector to the display seems ok.
Has anyone had this problem?
What did you do to fix the problem.
the connector out front
that connects to the sensor does it go directly to the display with no other connections under the hood.
If you did trace your 2 wires where are they located after they go under the fuse box
under the hood.
