What is the method for cleaning throttle valve carbon deposits?
2 Answers
Cleaning throttle valve carbon deposits can be done in two ways: 1. Non-disassembly cleaning: Spray throttle valve cleaner on a cloth and wipe the throttle valve. This method does not require disassembling the entire throttle valve assembly and is suitable for throttle valves that are not heavily soiled. 2. Disassembly cleaning: The entire throttle valve assembly needs to be removed, thoroughly cleaned with a specialized cleaner, and then reassembled. This method is more complicated as it involves disassembling components, but it provides a thorough cleaning effect. If the throttle valve is not cleaned regularly, dirt can cause it to operate less flexibly and allow impurities to enter the engine along with the air, which can affect the engine's normal operation. In severe cases, it may lead to reduced power, increased fuel consumption, and unstable idling.
I've been cleaning throttle valve carbon deposits myself for several years and find it quite easy to handle. The general method is: first disconnect the negative terminal of the car battery to avoid accidents; then remove the air filter box to locate the throttle valve position; spray specialized throttle valve cleaner on the inside and around the valve plate, applying multiple times to soften the carbon deposits; gently wipe off the deposits with a soft cloth or old toothbrush - never use metal tools as they may scratch the surface; after cleaning, wait for it to dry before reassembling all components; it's best to finally reset the ECU with a diagnostic tool, otherwise the car might experience unstable idling. Excessive carbon buildup can cause sluggish acceleration and skyrocketing fuel consumption, so it should be checked every 20,000 km. As a reminder, using high-quality fuel helps prevent buildup, making maintenance much easier. DIY cleaning can save hundreds in labor costs, but remember to wear gloves throughout and ensure proper ventilation - the cleaner has a very pungent odor.
