P0121 needs to be updated in the tune. P1892 related to a faulty TPS but this could be due to the tune as well.

So it either needs the proper changes in the tune, or the TPS sensor or its wiring is faulty.

I was getting weird throttle body error codes like you. Ended up that my throttle body was bad. Issue went away when I changed for another new one.
