Great video. You really go above and beyond for your customers. I had a rough idle on my 03 Corolla. I've taken apart my IAC further (the 2 screws on the front) and cleaned the internals with carb cleaner and a pipe cleaner to help improve the idle. The thing is, I figured out when putting it back, that correct orientation of the IAC motor is critical or the idle will surge, (which also set my check engine light). I loosened the 2 front screws a bit, clocked the IAC motor a little, and tightened them back down until the idle smoothened out. Also to aid in future cleaning, I replaced the bottom screws with hex bolts so I can remove the IAC with a 1/4 inch ratchet without removing the entire throttle body. It worked for me, but I take no responsibility for anyone else.
For the sake of a few more minutes work, I would have taken off the valve control motor to clean and check the valve shaft for free movement and to also see if there was any contamination on the motor that may hinder its movement. This would I’m assuming also give me greater access into the valve body to clean out any obstructions. Once all was clean I would then reassemble it all and test for correct operation. If the valve was perfectly free to rotate but didn’t, it would then indicate that the drive motor was as fault. Thank you for your helpful and informative videos, they are a great source of information to many of us. 👍
I cleaned the throttle body on my Tacoma and put in new spark plugs and it now runs like a top. All these auto’s need is a little TLC and they run for a long time. Thanks for all you show us Peter you are the best.
These are getting more exotic. I was used to the older Toyota on/off idle control valves and probably would have assumed this was the same. Thanks Petr!
Hello, you can take the electronic piece off and turn the shaft, there is a bearing that you can lube. I have successfully done this, try it, take care
Your awesome! Exactly the same problem I need to fix to get smogged! And the 02 sensor I'll be looking to see if you did a video on that. Thanks so much the help!
We scored when you chose not to work in Hollywood Peter. Great job, thank you. Too bad you can't get the spec for the voltage range applied to that thing, so you could attach a power supply and watch the axle rotate.
Just in case they are still having the issue. I had a similar issue with a 2005 Corolla XRS. The engine is the 1.8 but with some performance mods. It was idling at 1600 after warming up and the Check Engine light was on with the P0505 code. I did all that you did including replacing the IAC with a new Toyota OEM IAC. Looked for vacuum leaks, cleaned MAF, cleaned Throttle Body, still had the high idle and P0505 code. Finally I went old school and adjusted the idle screw. I was afraid the computer would freak out but it was successful. Maybe someone adjusted it before me when things were dirty? This was the final step in fixing my issue though. Thanks for the thorough walk through!
Got the same on my 98 maxima. Seperated the iac motor from the housing and a piece of electric tape was right where the pintal and housing were supposed to seal. But the iac was bad after my wife tested for a couple of days
I once long ago had a mid 90's Camry 5S-FE and I would do this maintenance a lot to make sure it stayed in top shape. I wouls seadoam the throttle body and some in vacuum lines too to help with this buildup
I suspect this Matrix was assembled in California. The Pontiac Vibe was also assembled there. As to the parts not made in Japan, this is expected, as the E130 Corolla was never sold there. Instead, they had slightly smaller version Corolla (E120). The E130 was an international version with assembly also in Canada. Southeast Asia also had E130, but was known as the Corolla Altis with large assembly plant in Thailand (9 different trim levels!!!). In US,.we only had CE (Classic Edition), LE (Luxury Edition), and the S (Sport).
Peter your Videos are informative but when it comes to IAC control valve i replace them metal and aluminum don't like each other. it will be more cost efficient to do that .Have a great day.Peter
Those little birdies sound so cute, Peter. Why don't you adopt them and keep them as the shop mascots? If there are two, you can name them Zauer and Kraut.
Very interesting and helpful. I got the same code an hour ago and had to find out why. This showed me right where to start. I also get PO442 but I’m told that it’s hard to locate the leak without a smoke machine. Is there any other way to check which ECS valve is leaking? Thanks for your help
Hello I have a 2006 Toyota Matrix check engine light PO 171 changed MAF sensor all 3 02 sensors and did a smoke check still shows PO 171 what do I do now Thanks
I HAVE THE SAME CODE ON MY 4 RUNNER AND HAVE TRIED 3 DIFFERENT BRAND NEW IAC VALVES ALL NOT SOLVING ISSUE HOW WOULD YOU CHECK TO SEE IF ITS THE ECM IS BAD????
Yes we can hear the birds, but I think they bother you more than us in the short time of this video. I think we may not have paid attention if you had not mentioned.
1MZ-FE non VVTi, high cold start idle of around 1800rpm - 2000rpm until the engine starts warming up then it comes down gradually to a perfect idle. Is that normal or an issue ? I previously replaced the original ISCV because it actually tested faulty. With a genuine Toyota/Aisan unit. Or has the computer learnt this a normal thus requiring a computer reset ?
Normal. Like he mentioned in the end by saying cold start. Toyota programs the ECU to do this so the coolant can get hot and circulate so the system gets to closed loop faster. You don't need a reset. Within some programmed drive cycles it will test itself out of the system and pass.
@@LAactor the company I work for offers dryer vent cleaning on apartment complexes. We deal with birds yearly in vents. They are pretty nasty creatures. They literally nest in their own poop.
So that IAC valve that's sticking (on the bottom of the throttle body) that you tried to clean with the spray and brush..... .....you need to take the electrical connector/electromagnet off to expose the valve shaft.....so you can twist it back & forth while you spray inside to unstick that valve. See here on this video ----> th-cam.com/video/WsP2-HKz7vE/w-d-xo.html th-cam.com/video/WsP2-HKz7vE/w-d-xo.html I've got a 2000 Camry whose IAC valve was stuck & the car WOULDN'T idle....had to hit the gas pedal to keep it running until it warmed up. I cleaned this valve just like that guy in the video above & it worked like a charm !! Just turn the key & the car starts & idles just fine. Of course, it could be a bad electromagnet which you probably replaced.....but if it was just stuck......you saved the customer some money
Great video.

A dirty MAF ( Mass Air Flow) Sensor can also effect idle, causing it to be high.
Owning a Corolla with a 1ZZFE, thank you for posting this. I haven't had this problem, but now I know what to look for.
This engine usually needs an intake manifold gasket eventually if it starts running lean . Make sure to use the orange upgraded one.
@@MarzNet256 Yeah? Thanks for that too.

Peter your a freaking awesome car mechanic i enjoy watching your videos
Another great video, Petr. You explain things so clearly and deliberately that even I can follow what you're doing. lol

Excellent. My 2006 Matrix has 195k miles and runs perfect. I try to maintain it like an aircraft. Best car ever!
This is my favorite channel currently. I’m replacing the head gaskets on my 3UZFE sc430.

Great video, Peter. Very educational. Cheers my friend.🇨🇦🇺🇸
Thanks so much Peter, I've an '04 Corolla, so this eng. same as mine! Thanks for the "INSIGHT"!
Thank you for sharing the results.
Got the same on my 98 maxima. Seperated the iac motor from the housing and a piece of electric tape was right where the pintal and housing were supposed to seal. But the iac was bad after my wife tested for a couple of days
That's a $275.00 OEM Part - depending on who supplies it - some are asking $350.

🦉🦅🐥love you videos
High idle can also be caused by bad 02 sensor
I gave it "thumb" up!
Hello I have a 2006 Toyota Matrix check engine light PO 171 changed MAF sensor all 3 02 sensors and did a smoke check still shows PO 171 what do I do now Thanks
Probably not using 91 octane or higher?
I HAVE THE SAME CODE ON MY 4 RUNNER AND HAVE TRIED 3 DIFFERENT BRAND NEW IAC VALVES ALL NOT SOLVING ISSUE HOW WOULD YOU CHECK TO SEE IF ITS THE ECM IS BAD????
Yes I think that's the general rule for the techs at the dealer. Don't touch it or if it breaks, it's now your responsibility.
Also general rule at home. If it ain't broken, don't try and fix it. Especially with me having a knack of making things worse haha.
Same problem for my 04 matrix xrs before sticky acc.pedal then engine light on P0505 idle air control valve
Was a Japanese Industry Standerd screwdriver used to remove screws or just a plain old American # 2 Philips star type??
It is a JIS
Yes we can hear the birds, but I think they bother you more than us in the short time of this video. I think we may not have paid attention if you had not mentioned.
Are you running the engine in an enclosed shop with no hose to vent exhaust outside?
Hey never know, maybe with some time the owner can use the italian tune up method on highway 5 and it will unstuck itself
👌👌👌👌👌
Can you tell me where your Masterskoi is located
where you from??? What country???
1MZ-FE non VVTi, high cold start idle of around 1800rpm - 2000rpm until the engine starts warming up then it comes down gradually to a perfect idle. Is that normal or an issue ?

Those birds would drive me nuts. I would get them removed.
Too bad he doesn't have shop cat

Aluminum does not "rust" it oxidizes and is called corrosion, in the form of aluminum oxide. Rust is Iron oxide.
correct! Rust= Really Ugly Steel Trash
So that IAC valve that's sticking (on the bottom of the throttle body) that you tried to clean with the spray and brush.....
.....you need to take the electrical connector/electromagnet off to expose the valve shaft.....so you can twist it back & forth while you spray inside to unstick that valve. See here on this video ----> th-cam.com/video/WsP2-HKz7vE/w-d-xo.html
