HOW DOES THE ELECTRONIC THROTTLE BODY WORK?


When you step on the vehicle’s gas pedal, the accelerator pedal module converts the pressure on the pedal into an electric signal.

According to the electric signal and outside variables, the ECU calculates the required intake air volume (in form of the opening of the butterfly valve), the corresponding fuel injection volume, and the optimal ignition time, that achieves the optimum efficiency and performance.

Important：

Professional installation is highly recommended. Instructions are NOT included.  

It is your responsibility to purchase the correct part.  Very often there is more than one part available per application as auto makers often switch midyear. eBay’s compatibility system does not allow sellers to account for any variations by VIN. If you don’t have the part number, you can get it from any dealership by providing your VIN. This way you can avoid unnecessary hassle and return shipping costs. We provide part numbers and high resolution photos, but if you do not check them we cannot guarantee fitment.

We can only be responsible for the damage and defective of our products. We cannot reimburse for any loss in any other parts of your car or labor cost.
