IAC Valve Testing and Cleaning

**PLEASE READ THIS VIDEO DESCRIPTION FOR HELPFUL INFORMATION**
In this video, we show you how to test and clean the IAC (Idle Air Control) Valve on your Toyota 5VZ-FE 3.4 Liter V6 engine. As a bonus, we show you how to clean the throttle body as well. The 3.4 Liter V6 motor from Toyota came with different throttle bodies. For example, 1996-2000 4runners came with the throttle body shown in this video. 2001-2002 4runners came with a different throttle body with a "built-in" air bypass. The same goes for 1st Gen Tacomas. 1995-2002 Tacomas will have the style throttle body shown in this video and the 2003-2004 models will have the newer throttle body design. For 1st Gen Tundras with the 3.4 Liter V6 engine, we don't know if they are the same with two different throttle bodies based on the model year they were made. But, a quick look at your throttle body on your engine will let you know which one you have. A dead give-away that you have the newer model throttle body is if you only have one cable running to it. You won't have a cruise control and transmission kick down cable like the one in the video.

** I wanted to understand better how the newer throttle bodies worked so I started a T4R.org thread and asked the forum members for some help. Instead of trying to paraphrase all the information that was shared, I thought it would be better to just provide a link to the thread so people can read through all the information themselves. Here's the linK: https://www.toyota-4runner.org/3rd-gen-t4rs/281621-2001-2002-throttle-body-design-question.html#post3422556 My screen name is "MTBTIM" on T4R.org.
