2004 CPM/Throttle Position Sensor

Check engine light came on and the jeeps idling/throttling was acting up. Stalled out, acted like it was slipping out of gear while driving etc..

Took it to the dealership and they replaced the throttle sensor switch.

Also had the clutch done.

Problem persists.

Dealership claims that the CPM is getting erratic voltage readings from the new sensor; though manual readings report just fine at 5 V.

Manual reading of old sensor shows that the sensor WAS the problem, but now the CPM is cooked.

Thoughts? Is there something that the dealership could have done that would have caused this issue? I really don't want to spend $500 more on a CPM after the $800 I just spent.
