Check engine light on, engine setting throttle position sensor high voltage. I replaced the throttle position sensor and still setting a hard code. Also cruise control quit about the same time. Any ideas?

On the new jeeps, some problems just can't easily be solved by shade tree mechanics. How did you find the error code? Do you have a code reader, or did you read it off the dashboard?
Most auto parts outlets have code readers they use on customers cars as a free service. They do that in the hope of selling you the parts you need. Some even have reference charts that will answer the question you've just asked here. They'll give you a list of possible causes, starting with the one having the highest probability of causing it. That would be my first stop. If that fails, its bite the bullet and take it to the thieves at the local jeep dealer. You've already tried the obvious one. If its the computer itself, its expensive.

One thing those two components have in common on a TJ is the clock spring...check the electrical schematics and they share a ground I believe. That's not an easy or cheap repair, but it's cheaper then throwing a bunch of other parts at it then replacing the clock spring anyway. I'd inspect the wiring and connections under the steering column shroud and around the TPS for possible shorts before paying a tech to guess at it at $120/hr.

Oh, the clock spring is the electrical connection under the steering wheel that allows it to turn whithout ripping wires apart.
 On the off chance the two problems aren't related, the usual culprit for cruise control failure is a vacuum leak. Do a quick check of the vacuum lines under the hood to see if one fell off.
