The IACV valve is operated by a step motor. This motor has winding phases and is actuated by the output signals of ECM. Each time the IACV opens or closes to change air quantity, the ECM sends a pulse signal to the motor. A certain voltage signal is issued so that the valve remains at a particular opening. Check with your vehicle's repair manual for testing parameters. This happens to be a '97 Nissan Maxima.

My idle seems to be a little high, it's idling now more or less at 1300 sometimes seems like 1500 , Do you think that the idle control valve could have something to do with this issue? I was thinking maybe it was possibly stuck open.. Thanks ahead again guys, you guys are always highly appreciated! 👍

Could it be that the throttle body needs a good cleaning, or what else would cause the code? Thanks in advance for your help and keep up the great work!

+doug resha Thanks man. If you checked the harness connector and the iacv, the '00 Maxima also has an air control valve on the power steering. If the vacuum hose or valve stops working correctly, you could get code p0505. You could pinpoint it quite quickly with a sophisticated scan tool. The basic scan tools won't pick it up.

Great videos. I have a P0505 hard code which I believe has something to do with either the ISC motor and/or ECM. But before I fix this code and spend lots of money, I noticed that all four of my readiness monitors are NOT complete. I understand the procedure to reset these readiness monitors, but do I need to repair this P0505 first BEFORE I can run the readiness monitors? Is there another option or procedure to reset these readiness monitors first? I know I can get several other codes when the four readiness monitors are run, but is there a way to reset these monitors so I have an idea of what else is wrong with my vehicle? I don't want to spend money to repair code P0505 ONLY to find out other codes later when the readiness monitors are run. Please help.

Great video, but I need to go a bit deeper. I want to learn exactly how the IAC steps, they are not simply fully open or fully closed, they can be set to various positions by the ECM to get different idle speeds. Yours has two sets of 3 pins. Pins 2 and 5 have 12V to them, then I guess a Ground signal from the ECM on pin 1 half steps the valve in one direction and then a Ground on pin 4 puts the other half step in that direction. To move the valve the other way, the ECM applies Ground signals on the 3 an 6 pins in a similar fashion. Is that correct? I have a GM 1987 2.8L V6 Fiero. My IAC valve has only 4 pins. I want to make a setup to actuate the value on the bench. My brother is an instructor at Porter and Chester and he would like to have a little set up to demonstrate how IAC valves work to his students. So learning how they actually work is the first step. I read 50 Ohms across each pair. I guess one pair moves the valve in one direction, and the other pair moves it in the other direction - but not quite, read on. I took some baby steps and tried it with 5V first... no action. Then I tried it with 9V (to be safe). One pair of contacts, still no action, but on the other pair puts a small twitch on the plunger in one direction (even if I reverse voltage polarity on the pair, it still twitches in the SAME direction). Ok, I guess it does use 12V, but seeing just a twitch is on right path. But the twitch was rotational on the plunger NOT in or out, and again, I expected it to twitch in the other direction using the other pair of contacts - but not the slightest twitch with those contacts! So, before I try it at 12V, I need to get a better idea on what signals/timing the ECM puts on the IAC valve to actuate it. There appears to be no position feedback from the valve to the ECM. I guess on power up, the ECM steps the valve many, many times to get to a fully open (home) position, and then the ECM keeps track of the step pulses to determine its position from then on - until power off. I have used stepper motors many times in the past, and that is what is nice about them, you don't normally need any feedback because the are dead on accurate on the position (and knowing it's position) if you pulse them properly. But I have no operational specs on my IAC valve. Any ideas? Thanks.

I have a 94 ranger 4.0 that has a very bad idle. Also when I hit the brakes hard it stalls out but only if its low on gas. I can replicate the stall every time but only when its getting close to e. If it has a quarter tank or more, it will not stall at all Sometimes when im at a stop it will jerk. Not sure if thats related. The iac valve looks super clean almost looks brand new. The only code its throwing I looked up and its mass af sensor which I already replaced. Also I can smell that its running very rich.

WaterWhipin Sounds like the fuel pump pickup is toward the rear of the fuel tank. When you're low on fuel and nail the brakes, the fuel is being forced away from the fuel pump pickup point and stalling out. Try to keep enough gas in the tank or you can burn out the fuel pump. The fuel acts as a lubricant for the pump. Regarding the rough idle, first thought is the idle air control valve. Other areas to look at include the fuel pressure regulator. EGR valve and PCV valve (I have videos for both) or you could have a leak at the air duct causing the MAF code. A bad idle can take some time to diagnose.

Mirko Miljanovic If the valve doesn't move then you'll need a new IACV.

I had some issues on my 2001 maxima and for p0505. And found that the intake boot badly cracked just before throttle body and got p0505. I replaced intake boot and cleaned the check engine light and it never came back. But strange sticky throttle Happened. Loose throttle cable fixed that but still had some strange idle. I had to do a idle air volume. Relearn procedure which is specifically for 2000-2001 maxima. After that it’s been fine. www.nissanhelp.com/diy/maxima/projects/2000_2001_nissan_maxima_idle_air_volume_learning.php Love your vids very clear and to the point.

HI Great Video very detailed! 2 quick questions please? 2001 Nissan Maxima. In park the rpm's go from 1200 to 1800, back to 1200 back to 1800. It does this very quickly and does not stop. Is this a symptom of a bad or crudded up IACV? Also I read one place that replacing the IACV could short the ECM or maybe when it fails it could short the ECM, have you ever heard of this? I'd like to prevent a shorted ECM from happening if possible when I go to check and possibly replace the IACV. Thanks a lot!!

Does this work for motorcycles as well? I’ve took my IAC valve of and left it connected..when I turn the key to on position, it doesn’t move at all.. Side note: I’ve been having problems with my motorcycle not being able to idle for more than 5 seconds..I changed everything but today I decided to check the IAC valve and it doesn’t move on the key on position

after replacing the sensor you will have to reset the KAM. this will make the pcm relearn its position. IAC is a stepped motor and it must relearn its position according to fuel trim and A/F ratio.

I have a 04 Ford Freestar that will act like it's running out of gas at first cold start. Fuel pressure is fine. If I hold RPM's at 3000 or more for a minute it will be fine but RPM's at idle are jerky. No check engine lights are on. Sound like the IACV to you? Thanks

All your testing checked out for me except for the last step at 5:20 on my 95' 3000GT. When I turned the car on several times, the shaft did not move at all. I decided to try it again and the first time I turned it on, it moved ever so slightly but wouldn't move again after I turn it back off and on. Is this an indication this part needs replacing?

Do I need to reset my computer on my 1999 Subaru legacy outback, after I check and clean my IACV? I didn't actually remove it all the way but after reassembling, my car is now acting like my battery isn't working for a minute. It starts but immediately dies. When I try to turn over again, it acts like I have a dead battery but if I wait a second then try again, it starts but not in a strong way. I know my battery is fine because I just got it tested. When my father and I replaced and adjusted my TPS the other day, we followed the recommended computer reset protocol and that got rid of the At Oil Temp and check engine light. It is shifting so smoothly now and all seemed perfect so we decided to see if we could clean the IACV, we were concerned we might screw it up so just shot carb cleaner into it and then put all the hoses and sensors back into place. Seemed to be fine until the next day when I went to start it and experienced it dying and then having issues starting. I've never had an issue with it starting. Wondering if i should've done the computer reset after messing with the IACV too. Or perhaps we didn't put something back correctly? Anyone have any advice here?

You mis-identified the leads from the AC to the connector. 2 became 5 on the IAC and 5 became 2. The terminal you stated was 2, became 5 when you went to the IAC.

I'm getting the code to suggest mu iacv us bad. When changing out the iacv am I required to install a new ecm? I've read in several place I should, but your vedio didn't suggest it. Btw, I talk your video as gospel as you do amazing work. One last thing I have a 97 infiniti i30 if that matters. Thanks.

+Bobby Gee Did you get this fixed? You need to check the ECM if its bad also. When the IAC goes bad, it shorts out the chip in the ECM (this is a common occurrence in maximas and i30s). You'll see a burned chip if you take out the ECM. GL
