What are the symptoms of a faulty Volkswagen throttle body?
1 Answers
After a Volkswagen throttle body malfunctions, the car may exhibit the following symptoms: 1. Failure to start or the throttle not returning to position after pressing the accelerator pedal. 2. Black smoke emitting from the car's exhaust pipe. 3. Increased fuel consumption. 4. High idle speed and unsteady acceleration. Here is more information about the throttle body: 1. Function: The throttle body is a controllable valve that regulates the air entering the engine. Once air enters the intake manifold, it mixes with gasoline to form a combustible mixture, which then burns to generate power. It connects the air filter at the top and the engine block at the bottom, often referred to as the throat of the car's engine. 2. Types: There are two types of throttle bodies: traditional cable-operated and electronic. In traditional engines, the throttle control mechanism operates via a cable (soft steel wire) or rod, connecting the accelerator pedal at one end and the throttle linkage plate at the other.
