What is the TPS voltage reading? Does the throttle unit have power?

Having similar trouble. Started with 12 codes now after replacing fuel pump and vapor management valve I still have 3 codes P2112 P2104 and P0451. Starts right up but idles very rough little response to pedal. I replaced tps and throttle body motor no change. Is it possible I need to have the PCM flashed? Any help or resolve to someone else's problem helps. Thanks!

You need a NGS (Ford factory scan tool) They can access the RAP KEYCODE PID.

P2106 is an informational code and is usually set by some other fault.

This DTC means is that the PCM detected a fault with the electronic throttle control and went into fail safe mode. It doesn't tell you specifically what system or component went haywire, just that something was wrong, the PCM didn't know what to do so it went to a known good operating parameter, in this case fail safe mode. Likely is a problem with the TPS sensor and will need to be replaced.

Hope this helps.

P2104 - Throttle Actuator Control (TAC) System - Forced Idle
P2112 - Throttle Actuator Control (TAC) System - Stuck Closed.
P2104 was set because the pcm had to step in to set the idle. The TAC system is in the failure mode effects management (FMEM) mode of forced idle. P2104 is just an informative code, set because of P2112. P2112 possible causes: Binding throttle body, stuck closed or
Damaged PCM

tell your dealer technician to follow pinpoint test DV1 in the workshop manual. (but also to reference test QE1) DV1 deals with him/her checking the throttle position voltages, if these voltages are not within spec, proceeding with checking for obstructions in the throttle body, then if this passes, he/she checks the wiring to the TAC assembly. there are many steps in this test and since the truck isnt here i can't tell you where the test will go (throttle body assembly, PCM, etc.) most likely it will be the throttle position sensor which is a part of the throttle body assembly or a simple connector coming unplugged or wiring being cut, but once again since i dont have the truck in front of me i can't be 100% sure. good luck. hope this helps.

I solved the problem I just made sure I wired according to the wires on the radio I took out

Could be any of the following. Coil, Distibutor Cap, Rotary Button.
