03 6.0 with codes p2139 and p2140

FordFanaticTony · October 16, 2009

Looking for help guys. I have an 03 f250 with the accelerator pedal sensor codes p2139 and p2140. PCED pinpoint testing led to replace app pedal assembly. Had to wait a month since it was on back order=funny, because I never had one go bad on me. Anyways he is back after 1000 miles with the same concern. Wont accelerate past 3 mph and p2139 and p2140 again. Any help would be appreciated. There is no chafe under the drivers side kick panel area in the cab. Possible PCM?

I had one where the shifter wiring on the steering column had a chafe grounding out and popping a fuse causing this concern.

+1, seen a few with the chaffed wire on column.

I thought of that since I have seeing that before too on 7.3. I looked at the wiring diagram for this 6.0 and doesnt seem as the circuit is tied in. I seemed to have found a chafe at the drivers side strut tower area. I rerouted the connector. So hopefully this takes care of it. Wish me luck.
