so my check engine came on so i pulled the code and i got a code 7 which is Throttle Position Circuit. so i did some research and the cause is Open or short in TP sensor, TP sensor, or the ECM. now how do i go about finding which one to fix/replace or whatever the corrective action might be? take it into the shop or should i just replace the TP sensor? and where the heck is this sensor located at? i'm thinking it's somewhere located on the throttle body.......but HELP PLZ!!!!
