Ok, you're the first person to tell me I can replace just the sensor (Don't get me wrong, I'm happy about that). Any suggestions on how to go about that or what part I need? When I search for parts, even by VIN number it shows I have a TPS (which I don't). The mech and the dealership is telling me it is one piece, and I can't get it separately, but I have a hard time buying that. Any input is appreciated. Thanks for your time.

The trouble code is caused by the TAC and actually I don't understand why the mechanic insists on replacing the APP as well.

TAC and throttle body is one piece but the APP is a separate item at a different location. Are you sure you got it right?
