...yourself job? And if so any input would be awesome. I got a diognostic test run and its a Po122 TPS/ Pedal position Sensor A.
Any help would be appreciated!!
 
This is what is refered to as a Fly by Wire throttle or ETC which means there is no throttle cable that controls the throttle. Throttle is controlled by 2 TPS's which are located on the throttle body. Neither of which are servicable. This could be a faulty connection, a bad TPS (1 0r 2) or a bad PCM. There is a 14 step diagnostic to determine where the problem is. If it's a sensor you'll need to replace the throttle body.
