The throttle valve is one of automotive parts responsible primarily for measuring the proper quantity of air going to a car engine. The use and operation of this component is practically identical in all petrol-powered cars. This component is located between the inlet manifold and the air filter.
Used car parts
Since the main function of the throttle valve is control of the amount of air flowing to the combustion chamber and engine cylinders, it decides on the air-fuel ratio. There is a “flap” located inside the throttle channel that changes its position depending on the foot throttle linkage. It allows the throttle to be controlled mechanically or electronically. Although this system seems to be relatively simple, its improper operation may cause severe problems with your car. In addition, the is a stepper motor and a sensor in the throttle body. In the case of dirty or faulty throttle components, the engine speeds up and runs unevenly.
Naturally, this increases fuel consumption and lowers vehicle performance. One of most common evidences of improper operation of the throttle valve and the steeper motor is spontaneous engine stalling when the car is shifted to the idle. Poor throttle response results usually from the use of poor quality fuel that contaminates it. Obviously, you can attempt to clean these components on your own, but as there is a wide range of used auto parts, a much more better option is to purchase of one of these parts. Any throttle sensor failure can be confirmed only based on the car diagnostic program. The sensor or throttle failure may result also from natural wear during prolonged use. When deciding to purchase or replace you should choose services that offer proven used parts for Opel and other car brands.
