the throttle position sensor is a sensor that is located on the intake manifold/throttle body to tell the ecu what degree the throttle is at so that your timing advance and all that shit will be correct. if your car is a non-turbo, it should be near the back of the intake manifold/throttle body, more to the right side. it's just 2 screws and it pops right off and then you pop the new one back in and the 2 screws go right back in and you should be good to go. as far as the price goes, autozone is pretty good about shit like that so i'd say just buy it and get ur car running again.
