[VanessaFitz]

When the EPC yellow light comes on in a Volkswagen, it is necessary to clean the vehicle's throttle body. The following are the reasons for the EPC yellow light coming on: 1. The issue is caused by a dirty throttle body. 2. It may be due to excessive carbon buildup. 3. Once the throttle body has a problem, it can lead to insufficient engine power, and in severe cases, it may cause the engine to stall while driving, affecting the normal operation of the vehicle. The throttle body of a motor vehicle is a controllable valve that regulates the air entering the engine. After the air enters the intake pipe, it mixes with gasoline to form a combustible mixture, which then burns to perform work. The throttle body is connected to the air filter at the top and to the engine block at the bottom, and is known as the throat of the car engine. The throttle body is one of the more important components in a vehicle.
