Hi I have a problem with my car v6 2.7 check engine light codes p0122, p1505, p1507, The car starts fine and it drives but when I start driving car doesn't shift normally like before it went to 2.5 rpms and then shifts to second gear now it goes to 4 rpms and then it shifts up, I have automatic transmission but it has option that you can drive like on manual + or - to shift up or down and it works fine. Please help

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.
