What causes the EPC light to illuminate and acceleration weakness in the Volkswagen Lavida?

[DiEverett]

EPC indicator light typically appears in Volkswagen vehicles. When this occurs, it indicates a malfunction in the vehicle's mechanical and electronic systems, often caused by a dirty throttle body. Cleaning the throttle body usually resolves the issue. More details about the indicator light are as follows: 1. Introduction One: EPC stands for Electronic Power Control, which translates to the Engine Electronic Stability System in Chinese. Many also refer to it as the electronic throttle. This system consists of components such as sensors and controllers, so when the light illuminates, it signifies a sensor malfunction. 2. Introduction Two: Normally, after opening the car door and starting the vehicle, the EPC light will illuminate for a few seconds during the self-check and then turn off. If it remains lit, it indicates a fault. Additionally, if accompanied by acceleration weakness, it is generally caused by a dirty throttle body.
