How often should the Corolla throttle body be cleaned?
2 Answers
Corolla throttle body should be cleaned every 20,000 to 30,000 kilometers. If the vehicle experiences significant idle vibration, generally cleaning the throttle body can solve the problem. In fact, there is no strict standard for how often the throttle body should be cleaned, as it largely depends on driving habits and environmental conditions - it should be cleaned when it gets dirty. From observable symptoms, when the car shows signs of unstable idle speed, cleaning should be considered. Introduction to throttle body: 1. The throttle body is a controllable valve that regulates air intake into the engine. After entering the intake pipe, the air mixes with gasoline to form combustible mixture gas, which then burns to generate power. 2. The throttle body connects to the engine air filter at the top and the engine cylinder block at the bottom, serving as the 'throat' of the automobile engine.
I've been driving my Corolla for a while. Generally, throttle body cleaning should be done every 20,000 to 30,000 kilometers, depending on driving conditions. Living in the city with frequent traffic jams and poor air quality, carbon buildup in the throttle body happens particularly fast, so I make sure to get it cleaned every 20,000 kilometers at the maintenance shop. If not cleaned, the car may shake, fuel consumption increases, and even the engine light might come on. Last time I forgot to clean it, the RPM was unstable at startup, but after cleaning, it ran much smoother. Friends who drive mostly on highways might need it less frequently, maybe every 40,000 to 50,000 kilometers. In short, adjust according to actual road conditions and don't be too rigid. Regular maintenance saves money and hassle compared to repairs.
