While driving loss of throttle, truck still runs and drives I have three codes P-2122 P-2121 and P2509 any help is appreciated?
The one code is a injector timing one, so anywhere in the fuel line could be off
I do not have Cummins codes so I would consider replacing the injectors or taking it to a Cummins service centre to have it fixed as the parts will not be cheap if not diagnosed correctly
SOURCE: p2121 and p2122
P2121 Code is throttle/pedal position sensor/switch D circuit range/performance
P2122 throttle/pedal position sensor/switch low circuit
Bad pedal maybe, does it return to idle?

Please check your ground wire they have a weak link there and have frequent problems on the ground curcit

your code is PCM/ECM power input signal intermittent. this is ussually a sign of a bad connection whether it be in a connector or a short or brake in a wire.
