Throttle position sensor, throttle body reprogram

So does your code reader show any live data?

Basic code readers Are just that all they do is read and clear codes. But a lot of the time more is needed when your diagnosing codes. Live data like seeing the cam sensor readings pedal position sensor readings. But to see those there not basic code readers there much more expensive actual scan tools. As far as the codes go the P2112 is putting the car into limp mode. Anytime the computer sees a failure in the throttle by wire system like a wire throttle body or pedal position sensor. The car goes into a reduced power mode for safety to prevent a out of control throttle situation. The code I would be afraid of is the code P0016 Because if the cam timing is off that means the timing chain jumped. If it jumped it will probably continue to jump till it jumps enough to bend some valves.

Some testing will have to be done To figure out the two different Problems some of them visual and some of them need some kind more advanced scan tool and or a lab scope depending on the capibiltys of the scan tool. If you are just basic Diyer this is going to a challenge for you. Iam trying to get you the trouble tree for P0016 so you can get a idea of what your in for.

Give me your zip code I will see what I can find.

Thats what I found in your area it got great reviews. At least they can give you a idea of whats going on.
