Removing the IAC Valve

• 1). Go under the hood and detach the negative (black) batter cable using a wrench.
  
  
• 2). Remove the air cleaner outlet tube, which is part of the air cleaner assembly that houses the air filter cleaner. This will give you better access to the idle air control valve. Use a Phillips screwdriver.
  
  
• 3). Locate the IAC valve and unplug its electrical connection. The IAC valve is located to one side of the throttle body, which connects to the air cleaner outlet tube you removed in the previous step. The air control valve is a small, aluminum cylinder, about 3 inches to 4 inches in length, with a metal triangle on each side of the upper part of the body and an electrical connector at the bottom. Two mounting bolts hold the IAC valve in place on the throttle body.
  
  
• 4). Unfasten the two air control valve mounting bolts using a ratchet, short ratchet extension and socket.
  
  
• 5). Remove the valve and gasket from the vehicle.
