Code P2135 occurs in reverse but only when backing up a hill.
Code P0222 occurs upon gentle accerlation.
If you stop the car and turn the key off both codes clear themselves and the car run fine.
The local Ford Dealer tried to address P2135 replaced the throttle body & motor assembly.
The local Ford Dealer replaced the module engine control EEC to address code P0222.
Both codes keep reoccuring and the local Ford Dealer is at a loss as to what to do to repair the vehicle.
Any help will be appreciated.

 

I am assuming both TPS's were replaced with the throttle body assembly. My guess would be a wiring issue between the throttle body and the PCM. Since you had the dealer do the work, paid a lot of money to them and they did not fix it, I would take it back to them. It appears the parts they changed were not bad or they would have fixed your problem.

 

The problem was finally resolved when the dealer replaced the engine wiring harness (Part # GU5Z12A581SQ)

 

Thank you for the update.
