Kia Sedona Dealer Problem
DTC P0122: THROTTLE PEDAL POSITION SENSOR A CIRCUIT LOW INPUT
DTC P0734 - 4th gear incorrect ratio.
DTC P0735 - 5th gear incorrect ratio.
Problem should be with P0122 which is causing a fault with the gear shifts. This is something that requires appropriate scan tools and wire cntinuity tests. It could be a fault with poor wire connections, open or short to ground in TPS wiring, faulty TPS or PCM (engine computer).
