DTC P0122 THROTTLE/PEDAL POSITION SENSOR/SWITCH "A" CIRCUIT LOW INPUT...
DTC P1505 IDLE CHARGE ACTUATOR SIGNAL LOW OF COIL #1...
DTC P1507 IDLE CHARGE ACTUATOR SIGNAL LOW OF COIL #2... A fault with the TPS would affect the transmission shifting so you need to get it checked.

I need help with these codes too on a 2002 sonata. We just changed the spark plugs and wires and now we have this code? Can't even drive it around the block! It revvssss high and doesn't shift right. Changed the TPS and the ACI? Now what?

Recheck the job done. The TPS and IAC wireharnesses could be loose or maybe interchanged?
