Just Bought 2017, bunch of CELs

i just bought a used 2017 with P0073 and NOW it has u11e9, u110e, had it about a week and this happened and the non-Chrysler dealer doesn't want to help and the local Chrysler dealer says it wouldn't be covered under warranty anyways ( i have 43k on it), I ended up taking it to a local mechanic that replaced the sensor but issue is still there, temp on dash shows anywhere from 20 to -39 when its 60-70s out and the A?C wont come on.

Update: replaced the Ambient temp sensor and issues still exists, having to take it back the dealership and I will be without the Van trying to figure out how to get kids to and from school.. this is crazy for a newish vehicle with only 42k on it.

I am starting to think that this is a EC/BCM issue which SHOULD be covered under extended warranty.

You might want to tell us if it is a gas or hybrid, and what trim level you have.

Did you purchase an extended warranty for this?

There is a TSB (08-133-18) for some 2018 models having a similar issue. The TSB mentions codes P0073, P1D73, and U11E9. It says the cause is corrosion in a 12 pin connector located near the left front sidemarker (must remove front seven fasteners of fender liner for access).

I think it's a wiring issue because of the U11E9 code (Lost Communication With Active Grill Shutter).

You may have a wiring issue in a different location, but I think this would be a good place to start.

The warranty you purchased probably won't cover it, but it wouldn't hurt to check. It's probably through a third party not affiliated with Ford or Chrysler.

I thought the active grill shutters were only on the hybrids - I’ve got a gaser and have no shutters

Did you buy this with a CEL? If so why?

Look again.

According to the dealer's brochure, ALL Pacificas have active grille shutters. Ours is a gas model and definitely has it.

This might be another option to check for repair. https://www.pacificaforums.com/forum/520116-post30.html

I looked extensively for over 30 minutes one day - I have the tow package maybe that has something to do with it? I even got flashlight and mirror and I found nothing that even slightly resembled shutters.
