Here are the trouble codes.
P1516 Throtle Actuator Control (TAC) module actuator position performance
P2135 Generic throttle pos sens/switch a/b correlation
I check with my scan tool to see if the accelerator was providing accurate info to the TAC. All I have is the tps abslte %. It seemed to provide smooth increase numbers all the way to wot. The problem is it reached wot at about half pedal.
