Getting dead pedal and hick up intermitently and codes P 0121 and P0122, have 2002 cummins engine

Question

Its a dodge not a ford as listed above

Answer 1

Hi there,

These codes are for a faulty throttle position sensor. Because it's not consistent I would first check the electrical connections at the TPS and any engine grounds that run from the engine to the firewall. If they appear good, I would replace the TPS and take it from there.
