I have a 2007 Liberty, Yesterday my EVIC Ambient temp reading went haywire. It is displaying 19*F the actual ambient is 110*F. When I UNPLUG the temp sensor the EVIC displays 130*F. What is the problem and how do I check?

Is it normal for the PCM computer to default to 130*F when the ambient temp sensor is unplugged??

Agreed for eight bucks it seems like your easiest and cheapest fix!

Where do you get a temp sensor for $8???????? I googled "2007 Jeep Liberty Ambient Temp Sensor" and all were $39-$59. Are we talking about the same sensor??? What my EVIC is displaying wrong is the outside air temperature, NOT the coolant temp.

I have a Ford Explorer, and a friend has a Chevy Silverado both trucks show dash marks(-- --) on the digital display when the outdoor temp sensor is disconnected.

The ambient temp sensor out in the grill which also feeds the EVIC its data is like $15 from the dealer here, possible you can find it for $8 but i haven't seen one that cheap. Stop by a Chrysler/Dodge/Jeep dealer and see if they got one. It used in many Chrysler vehicles.

No Prob. I'll check with my local dealer and give em that part # and see if it fixes the problem. I wonder why they are so expensive when I googled??

Well from what I understand a few years ago even the dealer charged that much . But they have come out with these new units that are cheaper and smaller and supersede the old units, I guess.
