2012 Dodge 3500 with intermittent dead pedal.
Starts and drives but then get a dead pedal response.
Changed the accelerator pedal sensor and it still can happen.
If you unplug the pedal it will "reset". No codes are thrown on the dash.
I took it to the dealer and they said they need a block of time to look at it.
Initial diagnosis showed "TCM U1400 implausible TPS signal received active".
They show things are communicating but can't find the problem.
Maybe a short in the wiring.
