Hello - this error code may be the accelerator pedal position sensor - as indicated. It also may be the throttle position sensor the matching electronic component on the engine itself, which directly influences engine power, and transmission shift quality. I would recommend a engine electronic throttle inspection by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.
