How to disassemble the intake pipe of the tenth generation Civic?

1. Remove air filter. The throttle valve of the pipe just removed is clean, but the back is actually dirty.

2. Turn on the key and step on the accelerator. Now the throttle is fully open. You can start cleaning, spray the accelerator cleaner on a clean cloth and then wipe it repeatedly.

3. The black part on the side of the throttle shaft is said to play a lubricating role and cannot be cleaned.

4. Because the plug on the air cleaner box is unplugged, a fault code is displayed. The fault code will disappear after the computer matches the throttle. Don't worry.

5. Check whether the water pipe leaks after matching the throttle.
