Lexus ES350 Throttle Body is a device installed in cars that controls the flow of air to the engine in reference to the driver's pedal pressure. Located between the air filter box and intake manifold, this has a butterfly valve that can open and close based on the amount of air required in the engine. Thus, in fuel-injected engines of the modern car, the throttle body is an electronically operated unit that receives signals from the sensors regarding the fuel supply to the injectors. Further, the throttle body might comprised of an Idle Air Control Valve (IACV) to regulate airflow at idle. Even though there are instances and specific vehicles that use more than one throttle body to aid in achieving better performance, the primary throttle body present in Lexus ES350 vehicles contributes significantly to the proper running of the car's engine.
