How often is the throttle of Honda CRV cleaned?

Generally speaking, the throttle of Honda CRV should be cleaned every 20-30 thousand kilometers. If the throttle is not very dirty, you can use the method of not disassembling the throttle, and the cleaning agent can directly clean the throttle. But it can be cleaner if you remove the throttle and clean it. The following are the specific cleaning steps:

1. First find the position of the throttle and connect it directly to the air filter behind the air inlet;

2. First remove the connecting hose between the throttle valve and the air cleaner, and then remove the air cleaner assembly;

3. Then remove the throttle cable, unscrew the fixing bolt and remove the throttle;

4. Spray the carburetor cleaner or special cleaner on the throttle, wait for the organic solvent to dissolve the carbon deposit, and dry it for 1-2 minutes.

In addition, there is another cleaning method, which does not need to disassemble the throttle, but only needs to spray cleaning agent into the throttle when the engine is running. The practice of many 4S shops and after-sales service centers is to spray cleaning agent into the accelerator while stepping on it. At this time, it will be found that the vehicle emits white smoke, mainly because the cleaned dirt is ignited by the oil suction pipe and discharged. This cleaning method is very harmful to vehicles. It is generally recommended to remove the throttle for cleaning, which will not cause too much harm to the vehicle.
