Today I swapped out my manifolds for ceramic-coated manifolds and replaced all the O2 sensors. I only ran into one issue where the metal lines that go into the manifold, one connector got stripped out. I was able to get the problem temp fixed until I get another one. So everything went well...so I thought. After replacing it, I figured I would go burn out all the excess coating, started the car and I received the "Err" on my climate control. So I figure maybe the cabin air flow sensor went bad. Replaced it and the same thing. What causes this other than the cabin airflow? I did have the bumper removed to get painted but when I picked it up I did not get that error unless something got loose on the way home. Any ideas?

By the way no other fault codes

 

After doing a little research it appears to be my outside air sensor. Must have come loose because I went to check the outdoor temp and I got - - F. Anyone know where it is?

 

The outside air sensor for the climate control is in the left front wheel brake cooling duct by the bumper fittings

 

Got under the car and the sensor was unplugged so I plugged it in. Started the car and still have the Er. I am getting the outside temp now so for sure that is working. Any other ideas?

 

I'm sure you've done this test

 

Problem resolved. Although I had reattached my outside sensor, I did not take it for a drive and let it calibrate. All good now
