Can the throttle sensor be cleaned?

The throttle sensor can be cleaned, and the throttle can be directly scrubbed by spraying the throttle cleaner on the wiping cloth. The whole process does not need to disassemble the throttle assembly, and the operation is relatively simple and easy. The cleaning effect of this method is relatively general, and it is only applicable to the throttle that is not particularly dirty. If your throttle is dirty and there are a lot of dirty things, it is best to clean it by disassembling and washing.

Let's take a look at the cleaning steps of the throttle sensor:

First remove the intake throat to expose the throttle valve, remove the negative electrode of the battery, turn off the ignition switch, straighten the throttle plate, and spray a small amount of "carburetor cleaner" into the throttle valve.

Then carefully scrub with polyester rag or high-spin "non-woven fabric". Deep in the throttle, out of reach, you can clip a rag and scrub it carefully.

After cleaning, the throttle will be initialized according to the disassembly procedure just now. After cleaning the throttle, it needs to be initialized, because the computer has a memory function when adjusting the throttle opening, because there was sludge blockage in the past. In order to ensure the air intake, the computer will automatically adjust the throttle opening to make the air intake in a normal state.

There is no sludge blockage after cleaning. If the throttle valve still keeps its previous opening, the intake air will be too large. As a result, the engine will shake when starting, the acceleration will be weak, and the engine fault light may light up.

The function of throttle sensor is mainly to monitor and control the air intake when the engine is working, just like the function of household faucet switch, which is a very important sensor in the engine electronic control system.
