It's the crank sensor!

Always, always follow where the codes point you to.
All three of them are for your throttle position sensor.
Replace it with one from either Jeep or Napa if you choose aftermarket. This sensor cannot be cleaned. Do NOT buy any cheap charlie engine management sensors; lots of Chinese stuff floating around that is absolute crap.
The part is not that inexpensive and it's easy to change. Plug and play.
Good luck and keep us updated if this resolves it.

Without "data", all you have is an opinion!
