Throttle Body Shopping Info

How Much Does a Throttle Body Replacement Cost?

A replacement throttle body could cost you anywhere between $100 and $250 on parts alone. A repair shop may charge $70 to $250 for labor, depending on the rates in your area.

What Is a Throttle Body?

A throttle body controls the airflow in your vehicle’s intake system. It contains a pivoting flat or butterfly valve that opens and closes to increase or decrease the amount of air coming into the engine. The throttle body is a part of fuel-injected cars and other vehicles that use carbureted engines.

On a fuel-injected engine, the throttle body is connected to the gas pedal either mechanically by a cable or electronically by wire. In an electronically fuel-injected car, both the throttle position and air flow sensors communicate with the computer, which, in turn, supplies the optimum amount of fuel to the injectors.
