These codes mean the throttle actuator has gone bad and needs replacement or it is unplugged.

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

Please let us know what happens. I am curious ;)

Recheck the job done. The throttle actuator wire harnesses could be loose or maybe corroded.
