Good day
Just want to find out if anyone has had this code 29E0 (Charge - air temp sensor Short circuit to B+ )

We have tested the Earth to Tmap and its fine.
The only thing is that my car stood for like almost a year without it starting or driving. Jb4 harness connected.

Car is in reduced power mode.

Check if the IAT reading is off compare to ambient temperature at cold start. Then, watch the IAT while your cruising. If the reading jumps abruptly up or down and the car gets a engine malfunction light, most likely you have a bad TMAP sensor.

I'm getting this code and reduced power after JB4 install. Triple checked the connections and everything is fine. I have no idea what is going on.
