What Causes the Throttle Control Function Failure in Volkswagen Santana?

[DiJuliet]

Volkswagen Santana's throttle control function failure is largely caused by carbon buildup inside the throttle valve. The problematic throttle valve interior is typically coated with black carbon powder resulting from incomplete combustion. Prolonged use of the throttle and poor driving habits are also contributing factors to throttle failure. Throttle Introduction: The throttle is a controllable valve that regulates air intake into the engine. After entering the intake manifold, the air mixes with gasoline to form a combustible mixture, which then burns to generate power. Connected to the air filter above and the engine block below, it's often referred to as the throat of an automotive engine. Throttle Function: Throttle opening refers to the angle at which the engine's throttle valve opens. The vehicle's throttle is operated by the driver via the accelerator pedal to adjust engine air intake, thereby controlling engine operation. Different throttle openings indicate various engine operating conditions.
