Nope, mine went in pretty easy with no codes. Did you remember to plug all the hoses and plugs back? There are several. One to the MAF, 2 plugs in the radiator area on the passenger side, and one hose that goes to the VaraRam.

No codes here. Recheck all of your plugs. I don't know if it matters, but what year is your car?

My IAT sensor wire broke internally right after my vararam install. I rigged something up to work until I can get a new part. Pulling apart the connector to fix it is a nightmare, but that is what I had to do to get it fixed.

The PCM doesn't use the feedback for the AIT sensor for anything other than pulling ignition timing.

I can't remember if it will go high or low if the circuit is open..

MY problem was NOT with the IAT sensor itself!! It was with the wiring harness that LEADS to the sensor. The IAT sensor feedback is used for more than ignition timing, it is used for fuel pulse modulation according to my 3 volume Corvette service manual.

Before I "fixed" the harness, I was having some harsh "garage shifts"-terminolgy of the service manual-afterwards the trans acted normally.
