The idle air control (IAC) valve on a Toyota Highlander is typically located on the throttle body assembly. It is usually mounted to the side or top of the throttle body, which is connected to the intake manifold. For specific model years, it's best to consult the owner's manual or a repair guide, as the location can vary slightly.
the idc or idle air controller is located on the left of the engine under the throttle body
A dirty idle air control valve could cause a 2003 Toyota Highlander to stall after being filled with gas. Also, make sure the gas cap is sealing tightly.
If you have just started it up it hasn't yet warmed up it will idle fast until the computer will read that it is warmed up to operating temperature. If the vehicle is already warm, it is likely that the idle control is out of adjustment OR that the accelerator pedal or the accelerator cable is sticking.
The Idle control air valve on Highlanders, and other Toyota models, and other makes and models of vehicles, becomes dirty. On my Highlander, the dirty valve caused the vehicle to sometimes fail to idle on its own until it warmed up. My research shows that most of the time these valves don't need to be replaced, they just need to be cleaned. If you can locate yours, and have decent mechanical skills, you can clean it and save the cost the dealer would charge to replace one. If you go to the website for "Tundra Solutions" you can find various posts on the Highlander issue, including my detailed summary of how to remove and clean one on a Highlander.
It is the IAC, the idle air controller will definitely cause that, about $50.00 and a half hour. Located behind the throttle body, back center of engine.
probably a bad idle air controller.
The location for the idle switch of a 1992 Toyota Previa mini van can be found in the Toyota Previa Auto Repair Manual 1991 thru 1995. This can be purchased from the Toyota dealership.
how do you adjust the idle on a 2002 toyota van
you can adjust it via the idle control valve.
Idle Control Vavle (ICV) is attached to the throttle body from underneath. Next to the ICV you can find two cooling pipes going through the changer where the valve operates.
It's directly underneath the throttle body and anchored to the throttle body by screws.
the RPM should idle 700 - 900
