the throttle posistion sensor is on the throttle body assy. the throttle actuator is off the gas pedal. check for stuff jammed under your pedal like a floor mat not letting it operate right. if not have it rescanned to see if it pops up or not. an auto parts tore scaner will not pic up the actuator.

the tps is replaceable but make sure that that is the problem before you wwaste your money. try cleaning your throttle plate on both sides with choke cleaner and the iac hole as it gets gummy and will stick alot of times. do that first cause it's cheap and you may not need a sensor. also clean around the tps sensor where it meets the throttle plate.
