It's the cylinder-shaped unit on the right side of the intake manifold that is toward the back of the engine bay. It has two hoses coming out of it one that looks like a black oval box.

Honda crx with auto transmission idles roughly in drive or reverse. AC on makes it worse.


There are two coolant lines that connect to this Honda IAC to help quiet the operation of the valve. The part number for a OBDI 1992-1995 Honda Civic Idle Air Controller is 36450-P28-A01. While the OBDII version of this valve is 36450-P2J-J01, and the two units are very similar in design and execution. The EACV or Electronic Air Control Valve is a big part of maintaining your Honda Civic idle. If you've checked your IAC and your Honda still suffers from a surging idle, check your FITV. This Honda Idle Air Controller or IAC is under the throttle body and incorporates into the throttle body passages o locate your Fast Idle Thermo Valve, remove the intake snorkel and locate the FITV beneath your throttle body opening. If your SOHC engine is still having problems, check our guides above on how to check your FITV as well as your IAC. To check this operation, remove your air intake pipe and use your fingers to plug the passages in the lower left hand corner of your throttle body opening. If your idle surge does not go away, unplug your Idle Air Control valve and if that stops your idle surge, your IACV must be replaced. Follow our instructions on how to replace your Honda Civic Idle Air Control Valve. Need to raise your Honda Civic idle or having problems maintaining idle? You can adjust the base idle by unscrewing or screwing in the Idle screw on your throttle body. This screw allows air to bleed into the passages on the backside of your throttle body, as shown above. To learn how to adjust Honda Civic idle speed, you will not need to remove anything. With a standard screwdriver, simply locate your throttle body and Idle screw.

Where is the location of the idle air control valve in a 2004 chevy malibu?


If there are no cables coming off throttle body to control throttle there is no Idle Air Control valve. the idle is controlled electronically by the computer. If car is idling rough you can clean throttle body to correct this problem. If you do have cables to control throttle the IAC valve is located right next to throttle body attached to it. Hope this helps

Diagnostics test says idle air control underspeed error? how do i fix 1999 ford explorer


change the idle air control valve.

Idle Air Control (IAC) Valve OPERATION The Idle Air Control (IAC) valve controls the engine idle speed and dashpot functions. The valve is located on the side of the throttle body. This valve allows air, determined by the Powertrain Control Module (PCM) and controlled by a duty cycle signal, to bypass the throttle plate in order to maintain the proper idle speed. Fig. 1: Typical Idle Air Control (IAC) valve which is mounted to the throttle body - cutaway view shows air bypass direction 89684g16.gif
--- REMOVAL & INSTALLATION
  1. Disconnect the negative battery cable. To remove the IAC valve, first disconnect the negative battery cable, then the IAC wire harness plug 89684p03.jpg
    Next, remove the two IAC valve attaching bolts . . . 89684p04.jpg
    . . . and pull the valve from the intake manifold 89684p05.jpg

  2. Disengage the wiring harness connector from the IAC valve.
  3. Remove the two retaining screws, then remove the IAC valve and discard the old gasket. To install: When installing the valve, always discard the old gasket and install it using a new one 89684p06.jpg

  4. Clean the IAC valve mounting surface on the throttle body of old gasket material.
  5. Using a new gasket, position the IAC valve on the throttle body. Install and tighten the retaining screws to 71-106 inch lbs. (8-12 Nm).
  6. Attach the wiring harness connector to the IAC valve.

How do i remove and clean the IAC


Operation

The Idle Air Control (IAC) valve adjusts the engine idle speed. The valve is located on the side of the throttle body. The valve is controlled by a duty cycle signal from the PCM and allows air to bypass the throttle plate in order to maintain the proper idle speed. Do NOT attempt to clean the IAC valve. Carburetor tune-up cleaners or any type of solvent cleaners will damage the internal components of the valve.

Removal & Installation

  1. Disconnect the negative battery cable.
  2. Detach the IAC solenoid connector.
  3. Remove the two retaining bolts and remove the IAC solenoid and gasket from the throttle body.
  4. Installation is the reverse of the removal procedure. Use a new gasket and tighten the retaining bolts to 71-97 inch lbs. (8-11 Nm).

Runs erratically


The idle air valve (located below the throttle body) provides the control for constant idle speed. In order to set the correct air valve opening to achieve constant idle speed, the fuel injection control unit uses information from the air mass meter, throttle valve switch and the ignition control unit (RPM signal) to regulate the output current to the idle air valve. This means that the idle valve is not affected by air leaks or a jammed throttle valve.
