I just installed a turbonetics kit on my 2008 scion Tc; I am having problems with my car when I go into boost. My car will shut off when it start to hit 1 or 2 psi of boost, and then check engine light comes on. So I took my car to S&R Performance to get it looked at and tuned, they said the check engine light code is p1122 throttle body stuck closed. They don’t know why it’s closing when you are going into boost, and they don’t know how to approach this issue. Is there anybody that may know what the issue is, or a shop around Tampa that knows more about the scion Tc.

 

Call Turbonetics
Ask on the Scion boards you'll probably get more hits than here.

 

does the map sensor on the car accept positive pressure? or is it maf?
that cose is for low voltage to tps, perhaps you have a faulty tps sensor.
Is the throttle body electronic or cable type?

 

Nice meeting you again Oscar and have fun with the car

 

Ohai Alpha, lol.
