Hi guys, I noticed today that my temperature is way off from what it really is outside It just stays at 80 and doesn't move my question is is this sensor easy to replace? I've been watching a lot of videos saying you have to take the bumper off? should I just send this to a shop or should I try to fix this myself is it worth it? Or could it be a glitch in the radio but it needs to be reset the my link? Any suggestions would be great thanks so much

Before you do anything, did you recently have work done to the vehicle or disconnect the battery?

If so, just drive at least 10 miles and make sure you get above 50 mph for some of it. After that, the temp should start reporting again, but if it doesn't, then get the codes read (not just the P codes, but all of them) and see if there's an issue.

I have noticed it stick once in a blue moon and driving it makes it work again. Maybe 3x in 4+ years of owning it.

P0073 and a crack in the shutters leads me to suspect impact from an object which means connector/wiring damage.

Seems you have it all figured out! Saves me pulling out the diagrams to sort it out.

The first time I heard about it, it was a service writer who told me. It was hard to swallow, but when I drove it and it got to 10 miles, Bam!
