Why is throttle body cleaning so expensive at 4S stores?
1 Answers
Because throttle bodies are controlled by the engine's computer, cleaning the throttle body (especially disassembly cleaning) usually requires specialized diagnostic equipment to rematch the throttle body afterwards. Ordinary repair shops may not have this diagnostic equipment, but 4S stores definitely do, which is why throttle body cleaning is more expensive at 4S stores. Below are specific details about throttle bodies: 1. Throttle Body Introduction: The throttle body is a controllable valve that regulates air intake into the engine, with two types: traditional cable-operated and electronic throttle bodies. After air enters the intake manifold, it mixes with gasoline to form a combustible mixture for combustion. The responsiveness of vehicle acceleration is closely related to the cleanliness of the throttle body. 2. Throttle Body Classification: There are two types of throttle bodies: traditional cable-operated and electronic. Traditional engine throttle body mechanisms operate via a cable (flexible steel wire) or linkage rod, connecting the accelerator pedal to the throttle linkage plate. Electronic throttle bodies primarily use throttle position sensors to control the opening angle of the throttle body based on the engine's energy requirements, thereby regulating the amount of air intake.
