Toyota VIOS Throttle Cleaning Tutorial Here is a detailed cleaning tutorial for everyone.

1, start to remove the throttle. First remove the air cover.

2. Begin to disassemble the throttle assembly.

The throttle valve has been removed, but it is necessary to disconnect the two water pipes above, which are used to cool the throttle valve.

4. After the two water pipes were successfully dismantled. Then plug it with an old spark plug. Prevent antifreeze from flowing out.

5. The removed throttle is dirty, and then the throttle should be taken apart. First remove the idling motor, which is also dirty and full of carbon deposits.

6. The idle motor also needs to be decomposed again, and then the carbon deposit in the airway next to the idle motor is cleaned. Then turn around to see if the rotor inside is still stuck.

7. Spray it with detergent. After cleaning, the compressed air is dried.

8. Secondly, start cleaning the throttle body. It is necessary to remove the carbon deposit on the throttle baffle. Rub hard. If the carbon deposit takes too long and starts to harden, it can't be wiped off with Puckilo, so it should be scraped off with a fine screwdriver. Then blow it clean with compressed air.

9. Finally, assemble the idle motor, bypass pipe and other components. Then tighten it with a Phillips screwdriver. Clean the throttle and install it on the vehicle. When loading the vehicle, fasten the screw with the quick ratchet after installing the throttle. Install the air cleaner cover, and the whole throttle cleaning operation is completed after installation.
