How to Clean a Toyota IAC Valvethumbnail
Keep your Toyota running smoothly by cleaning the IAC valve.

The idle air control valve in the Toyota is an important component in controlling the Toyota's idle speed. The valve, commonly referred to as the IAC valve, allows the correct amount of air to bypass the throttle plate in order to maintain the proper idle speed. The valve will become dirty over time and cause the Toyota to stall or idle roughly. Cleaning the IAC valve takes a few short steps and can be completed with minimal tools. It's important to keep the valve clean to ensure the efficiency of the Toyota.
