The code is for the TPS , several things can cause this tps not plugged in , or plugged in after the car was started. If the car runs good go to auto zone let them erase the code for free with their scanner and then see if it comes back on. most likely it was just a accident. but go check to make sure it is plugged in and that the wires to it are not pinched in any way.
