Air idle control valve location

Good afternoon,

Yes it does. it is located on top of the throttle body. Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.

I am having problems with my truck, 2004 Ford Explorer, Eddie Bauer Edition, 4.6 liter engine V8, check engine light is on and it idles up very high at times, causing it to jerk off very fast and my air will not get cold unless you are on the gas. I took my truck to Autozone and they said the IAC is not even on the truck but the diagnostic is reading IAC, could you please show me where it is located?

clean throttle plate on both sides with choke cleaner then clean maf. Yours doesn' t have an iac. then look for brokein grommets or ones with holes in them also check for vacuum leaks.

Thank you hmac300, I had been racking my brain for days wondering where this part was, and now I guess my husband won't have to hear my mouth much longer. Thank you much!!!!

he could hear it in different ways lol

I am having the hardest time locating my Idle air control valve. The pictures I've seen doesn't match what i see on my motor. Can anyone help? As of right now my truck will not continue running.

Hello,

Your car is drive by wire so It does not have an IAC motor becasue the throttle body actuator acts as the IAC as well. Here is a guide to help you see what I am talking about.

How much shoud it cost to repair an Idle Air control vavle? The repair shop I have used for the last 20 years was just sold and I had the job done for $295. It included $90 diagnostic, $45 labor and $129 parts.

Sounds reasonable, if your having it replaced again subtract the diagnostic fee, as you know what it is the parts are aroudn 100-150 dollars dependent. the labor is from 50-100 dollars also.

I am experiencing a humming or rumbling noise from my explorer when i am decellereting to idle. the noise happens at low rpm's and only when decreasin g. It sounds like it is coming from the air intake just before it enters the ebgine.

More then likely this would be the idle air control so here is a guide that will explain how to replace this plus a guide that talks about noises from a vehicle. Please take a look at number 6 on this guide that talks about this in more detail.

Lastly below is the process from the manual on how to replace the IAC. Please let us know if you have more questions. Thanks

2001 Ford Explorer 6 cyl Two Wheel Drive Automatic 101K miles

Sir, great site! I have an '01 Ford Explorer Sport with 101K on it. All plugs, wires, filters, fluids flushed, etc. Everything is done. Recently was told engine air idle control valve was bad. Idled at 650 rpm's and unsteady. Never bothered me but thought I'd go ahead and replace the valve. After doing this I cleaned the MAF sensor with correct cleaner and started it. Worked fine for a few hours, idle at 900rpm's smooth. Then check engine light came on, engine rpm's go to 1500 when cold and stay there pretty much anytime it's in neutral. Ran the codes and said O2 sensors bad. Reset codes and now no codes, but rpm's are internitent from sometimes perfect to other times 1500 even when warm. Thanks.

Sounds like your new IAC valve has issues. In fact, I've had this problem myself. I replaced the IAC valve because the vehicle would not idle on it's own. I could hold the throttle open a little and it would idle fine but as soon as I let off the gas, it would die. Well, I replace it and then it idled at nearly 2000 rpms. No matter what I did, that was the case. I got disgusted and ordered another IAC valve and it worked perfectly.

My Mom's Ford Explore has a check engine light. Went to Autozone to get the code. I did some research about the IAC valve. Do you know the location of the valve so that it can be cleaned?

There you go its figure number 4.

This happens every morning, worst when its cold, start the car it dies almost instantly, start the car again must keep car revs high or it will die. get the car of the drive and lift foot of accelerator to brake the car will die (not good power steering doesn't work).Start car again after car has warmed up 3 Min's the car is perfect, could this be that the idle control valve is not working my friend a mechanic thinks this could be the prob but his computer is not a ford computer so it cannot find the problem and forking out £80+( yes pounds not $ UK car) for a new idle valve for a hunch is not my thing

Thank you

Paul

SO your saying that after the car warms up the idle is perfect and you do not have to hold your foot on the gas?

Yes the car idles perfect when the car is warm its just first thing in the morning, have change the water temperature sensor and that has made the car run better but has not stop the problem in the mornings.

if its warm in the morning it still has trouble starting also?

Where was the sensor located that you changed there is the coolant temp sensor, and one for the temperature guage.

The sensor was towards the top of the engine in the middle under the plastic housing the computor said that the water temp was 80deg when the car had only run for 30 seconds. the other question about the car starting if the weather is warm i cannot answer yet. I am shaw that it was the coolent temp sensor.

pull the wires off of it and if the temp guage goes to 0 or full red bar then that is not the coolant temperature sensor.

where is it located and how to tell if it is bad?

Idle Air Control (IAC) Valve The IAC valve, mounted on the throttle body, controls idle speed by regulating throttle plate by-pass air. IAC valve includes an air by-pass valve and idle speed control solenoid valve. The air by-pass valve is affected by the engine coolant temperature and functions during cold engine conditions less than 122 °F (50 °C). The idle speed control solenoid is controlled by PCM and works throughout the entire temperature range. On some models, idle is controlled by idle speed control air by-pass valve. A throttle air by-pass valve is a solenoid-operated valve controlled by PCM. The valve allows air to by-pass throttle plates to control cold engine fast idle, no-touch start, dashpot, overtemperature idle boost and engine load idle correction. Air by-pass channel carries idle airflow regulated by air by-pass valve. Air by-pass valve is controlled by PCM to adjust both cold and warm idle speeds. Air by-pass valve uses solenoid valve to vary idle airflow volume allowed to enter engine

Idle Air Control (IAC) Solenoid Solenoid is by-pass air type. Ensure ignition is off. Disconnect IAC solenoid harness connector. Set DVOM to 200-ohm scale. Measure resistance between IAC solenoid connector terminals. See Fig. 3 . Solenoid has diode. Connect DVOM (+) test lead to terminal VPWR and DVOM (-) lead to terminal IAC. Resistance should be 6-13 ohms. If resistance is not as specified, replace solenoid. Faults in IAC solenoid or circuit should set a service code. See QUICK TEST in appropriate TESTS W/CODES article in the ENGINE PERFORMANCE Section. If no service code has been set, see CIRCUIT TEST KE in appropriate TESTS W/CODES article for additional testing and specifications.
