I'm not sure if I knocked something loose, but now I'm not getting a reading on my PFC. I didnt post in that section becuase I dont think it has to do with the PFC. What can I check ? All I did was clean the grounds for the PFC, I could have knocked something loose though or maybe the IAT sensor went bad?

 

Have you checked the connection on the IAT? If it's still in the stock location, the IAT is located under and near the middle of upper intake manifold. The ground strap from the UIM to the firewall is sort of in that area.

 

What do you mean when you say you "cleaned the grounds to the PFC"? Did you unbolt the grounds from the UIM?

IAT sensor is the blue one

 

I had the same issue with my sons FD and it was a faulty AIT sensor.

 

I forgot to plug it in. What a rookie move, lol

 

We've all done it.
