Why the whole throttle body
Customer: replied 3 months ago.
I do not quite understand how this works with the throttle body to my understanding that has the throttle control actuator on it and then the throttle position sensor in the throttle body is just metal housing can you better explain to me why I can't replace the other two parts instead of the whole throttle body
