Should the Throttle Body Be Cleaned?
1 Answers
Throttle body cleaning is necessary. Here are some key points about throttle body cleaning: 1. The throttle body is a controllable valve that regulates air intake into the engine. As air contains dust and sand particles, impurities accumulate on the throttle body surface during airflow. Combined with oil vapor from the crankcase, this forms a black carbon-oil deposit layer. 2. Excessive dirt buildup can cause throttle movement stiffness and allow contaminated air into the engine, affecting normal fuel combustion. The throttle body should be cleaned every 20,000 to 40,000 kilometers. In harsh driving conditions, more frequent cleaning is required. However, over-cleaning may lead to premature throttle failure as the special coating inside the throttle chamber gradually wears away, making it more prone to oil deposits and creating a vicious cycle that ultimately results in throttle body failure.
