Hoping someone can help, the other day my Boss started throwing P2127 and P2122 at WOT. Figured it was the accelerator pedal, or APP sensor, so I ordered one without troubleshooting it at all.
Pedal did not fix it, so it was time to go further, I've verified no wire breaks through continuity testing (.5 ohms per wire PCM connector to APP sensor connector)
I do indeed have 5v at the pedal on both app1 and app2 (4.9994 but hey), I've simulated the pedal being pressed with a fused jumper and it doesn't respond on one of the channels.
Now I can't get the codes to clear at all, I'm thinking it's a PCM issue but I don't know a way to verify it or if you can verify it.
If anyone can help, or sees something I'm missing it would be appreciated.
Thanks in advance.
