Default electronic throttle control issue

2008 dodge ram 1500 mega cab with 5.7 hemi
this started about a week and a half ago. the etc light came on and i lost all throttle pedal function. i borrowed a code reader and got the following codes
p0122- throttle pedal position sensor switch a circuit low input

p1607 pcm internal shutdown timer rationality.

i sent the truck to the dealer and they said there was an open within the throttle body,so they replaced the throttle body. i got my truck back last friday, after they kept it for over a week.

truck ran fine on the way home friday evening and all day saturday. then yesterday it started doing the exact same thing again,except now the check engine light has come on. when this initially started the check engine light did not come on. so now i am wondering if they replaced the wrong component or if something is wrong with the pedal position sensor, or another problem somewhere else. its going back to dodge tuesday morning. this would happen on a holiday weekend.

any thoughts as to what might be going on? i am open for input from yall.

Its possible. Take it back and make them correct it if it has the same code or issue.

Im not sure on their thought process but this sounds like a circuit or PCM circuit problem more than a bad throttle body issue.
