Dodge-3500 Pickup - Error code P2122 & P2121

the local Dodge dealership gets this code and no-one there knows what it means!! Unbelievable... truck keeps sputtering - like it's going to stop - has already done that once. Dodge said it was a throttle sensor - which is not covered by bumper-to-bumper warranty - so, I pay $400, get it put in and it still sputters. Anyone know what the P2122 and P2121 codes mean? Or, anyone have this problem with their Dodge?

i know the p code 2122 is the a.p.p.s or accelerator pedal pisition sensor. and the p2122 is low circuit voltage, i believe the p2121 is dead apps but not positive on that, i know if you have just code p2122 the apps with fix the problem
