Default Throttle Pos Sensor

Im throwing a code of p0122 thr pos s a cir lo in. after installing a 70 mm accufab throttle body. Could my throttle pos sensor been damaged in transferring it to the new TB or could the screw be set wrong on the new TB which I never touched. Any Help is appreciated.

When you install a t/b n plenum the tps gets all ****ered up, and it usually takes a couple weeks for the car to adjust and get rid of the hanging RPM's. Update your tune, and it should solve your problem. At least thats where I would start, otherwise I'd be willing to bet if you drive it long enough it will fix itself if you never touched the TPS, might clean it to be on the extra safe side.

so if the voltage isnt there or not enough then I would assume it somehow broke when removing it and putting it on the new TB??

Would you guys trust a place like autozone to buy em from or should you purchase it from a dealership. I live right by the biggest mustang dealership in the midwest which i go to all the time but they are more expensive.
