Why is throttle body cleaning so expensive at 4S stores?
1 Answers
4S stores charge more for throttle body cleaning due to the following reasons: Since throttle bodies are controlled by the engine's computer, cleaning them (especially when removed for cleaning) usually requires specialized diagnostic equipment to recalibrate the throttle body. Such diagnostic tools may not be available at ordinary repair shops, but 4S stores definitely have them, which is why throttle body cleaning is more expensive at 4S stores. Here are detailed introductions about throttle bodies: 1. Throttle Body Overview: A throttle body is a controllable valve that regulates the airflow into the engine. There are two types: traditional cable-operated and electronic throttle bodies. The air entering the intake manifold mixes with gasoline to form a combustible mixture, which then burns to produce power. The responsiveness of a car's acceleration is closely related to the cleanliness of the throttle body. 2. Types of Throttle Bodies: There are two types of throttle bodies: traditional cable-operated and electronic. In traditional engines, the throttle body's operating mechanism works via a cable (soft steel wire) or linkage rod, with one end connected to the accelerator pedal and the other to the throttle linkage plate. Electronic throttle bodies primarily use throttle position sensors to control the opening angle of the throttle based on the engine's power requirements, thereby regulating the amount of air intake.
