i have a 2015 f250 6.2 auto 4x4
the throttle body went bad we orignally thought it was a fuel pump.
truck now has a new fuel pump new fuelpump relays, new motorcraft throttle body
ive overlayed the wire harness from both the throttle body to pcm and pedal to bcm
it will start and idle but at aout 75% pedal it goes into limp mode

using forscan tp2 gets to 3.5 volts then drops 1 volt. tp1 at same point jumps 1 volt. pedal graphs out smooth and constant,

i am getting a 2111 and 2135

 

To check and see if there is a wiring issue every single relevant wires you check resistance on both ends with the electrical connectors unplugged. For example, all the wires between your APP (Accelerator Pedal Position) sensor and PCM, between PCM and your TPS, simply ALL the linkage. If everything is new and no wiring issue, never rule out your PCM is the culprit. If that's the case, check ebay sellers doing ECU repairs, you tell them the problem, you ship them they fix it and ship it back to you, no reprogramming needed. It's cheaper this way than keep throwing new parts at your truck.

 

im pretty sure its the pcm i believe I've ruled out most everything else. just frustrating thank you for the reply

 

is there a particular repair person on ebay you recommend

 

No. Simply find any, check the seller rating and when the account was established. You tell them the problem, give them the exact DTCs, and what you have done, they will let you know if they can fix or not. If they can't fix they wouldn't even take the job, if nothing is fixed you don't pay, no risk for you to just ask.

 

sent PCM out it came back good no faults founds any other ideas
