Description

Function of the Throttle Body

The throttle body controls the amount of air entering the engine based on the accelerator pedal position. It contains a butterfly valve that opens and closes to regulate airflow, directly controlling engine power output. A dirty or faulty throttle body causes erratic idle, hesitation, stalling, poor throttle response, and a check engine light.

Why order it from Partszar

An air or exhaust fault strangles the engine and pushes up fuel consumption, and left alone it sends unmetered air, soot or oil into the turbo and the DPF. Fix the small part and the big ones stay out of the workshop.
