Does a Dirty Throttle Body Affect Fuel Consumption?
1 Answers
A dirty throttle body can affect fuel consumption. The fuel injection amount is calculated based on the air intake volume, and the throttle opening is adjusted by the accelerator pedal. A dirty throttle body can affect the opening degree. To maintain normal air intake requirements, both the air intake volume and fuel injection amount will increase, leading to higher fuel consumption. Methods for cleaning carbon deposits on the throttle body: Non-disassembly cleaning: Spray throttle valve cleaner on a cloth and wipe the throttle body. The entire process does not require disassembling the throttle body assembly, making the operation relatively simple and convenient. This method is quicker and easier for car owners, as they only need to purchase the cleaner themselves. However, the downside is that the cleaning effect is average, making it suitable for throttle bodies that are not extremely dirty. Disassembly cleaning: The entire throttle body assembly needs to be removed, then thoroughly cleaned with a specialized cleaner before reassembly. This method is more troublesome as it requires disassembling the components, but the advantage is a thorough cleaning effect. Precautions after cleaning the throttle body: After cleaning, the throttle opening must be reset. Otherwise, if the throttle opening changes but the car's computer still operates based on the pre-cleaning state, the idle speed may fluctuate erratically.
