- How to fix issues with bad idle speed VVT-i engine Toyota Corolla.Years 2000 to 2015 Air leaks are in intake manifold, air leaks in hoses and dusty in MAF air flow sensor.
Reason for the higher rev range at first start up is older vehicles like these start with a higher idle speed to reach proper operating temperature first. After which it’ll begin to drop and finally idle around the 700 range. If you look at newer engines and how newer vehicles idle at start up, they begin at a low idle because it has better monitoring and sensors to be able to obtain the best air to fuel ratio. These older model vehicles don’t have as good sensors and monitors to keep the rev range low at initial start up.
But the idiling come down but go up again
I fixed my 06 Vitz in 5 minutes,adjusted the accelerator pedal switch block its adjustable just go behind the accelarator pedal and you will see a slotted black box with 2 screws,loosen the screws and moved the black switch box and few milliemetres and hey presto idleing beautiful.I dont disagree with what Peter is saying,but my car was nearly stalling and badly shaking,will do the correct things soon.
Thanks for feed back. 👍😀
This is what happened to my car today,, thanks to Peter. Tomorrow I can point out to the w. Shop. Thanks 👌👌👌
Glad to help
Finn you are a savior, thank you so much for saving me tons of stress, money, and time replacing my alternator and now diagnosing the low idle problem with my 2006 Toyota corolla. Did you make a video on how to remove and replace the intake manifold?
trkoby Thanks and here is intake video: th-cam.com/video/nXozHsF4C38/w-d-xo.html
I have worked on Toyota's for almost three decades. The mid 90's and newer have been prone to intake manifold gaskets leaking causing a wide variety of problems.
Good info 👍😃
Thank you Peter , you explain very well and save time for so many . kind regards to you
Dirty mass airflow sensor reduces fuel economy not the idle. It usually the dirty "Idler control valve sensor" that causes the idle to drop to 500-600 RPM. This problem causes the alternator not to be able to produce enough charge and Overtime, this reduces the life of your battery and alternator. This happened to my 2007 Camry, and the only way is to clean the ICV sensor and lubricate the valve, which sits on intake air manifold right after air filter assembly.
+kourosh tari Good info. :-)
I already cleaned but still the same
kourosh tari engine light won't come on
kourosh tari Toyota Corolla won't light engine won't come on won't start
kourosh tari ,yes u r correct (clean the ica valve ). Also u can adjust the idle speed by yrself very easy too.
Had rough idle issues on my 2010 Corolla for years. Did the basic checks; air filter, mass airflow sensor cleaning,etc. Turns out it was a leak from the intake manifold and a sticking PCV valve. Replace the valve since you already have access to it when replacing the manifold gasket.
Good comment, thanks 😃👍
Two Screws, and a screwdriver, killed really good information! Keep up the good work.
Thanks and noted 👍😀
Actually I had this problem with an 06 corolla now I’m having it with an 06 Matrix 1zz ... cleaning the MAF sensor did help. I also replaced the PCV valve at the same time. Doing the same thing on this matrix and the timing chain tensioner
When the engine is cold like in the morning, it is normal for the rpm to be high for some minutes. It should go down as it reach operating temperature.
Yes
Yes because it revs higher as the cold engine is trying to warm up quickly, so as to reach normal operational temperature as quickly as possible. More important in winter times where the temperature gets really cold and when it snows as well.
It help a lot to use a small film of electric grease or vaseline on o ring. So you don’t pinch it and it slide right in and seals. Electric grease also conditions the rubber o ring
😀😊
I have a toyota sienta rev counter is at 500 it switches off if u stop how can i adjust it to 1000r per minute
Thanks for this video. Appreciated. The Australian 2008 engine is not the same as this. I found my sensor. It's smaller and easier to remove in slightly later engines. After a good clean idling seems to be perfect now. They want $250 for a new one here in OZ so maybe try removing and cleaning first.
Thanks for the info!
Thanks very well explained. Do you have any tips for a verso being hesitant when increasing revs, particularly when at a road junction or roundabout?
Clean throttle body, set the spark plugs gap check ignition coils..
Noted, good point. 👍
Dude, the area of the MAF sensor you were referring to is the intake air temp sensor. Time is combined with the MAF. The actual MAF part is inside the passages next to the air temp thermocouple. If you look inside these passages you will see two small "wires". That is the MAF part of the sensor. That must also be cleaned. Very carefully.
Thank You for comment. :-)
Exactly what I was seeing!!! You said it for me!!! I agree with your comment.He is not seeing the other two wires!
Replace all four ignition coils with a Denso brand, will idle extremely well if everything else is operating normal. Big improvement.
Yes, good work. :-)

Getting a rough idle in my Toyota Corolla. Will try cleaning this and hope it works.
Clean the throttle body too.I would remove,clean or replace the PCV also as doing all 3 of there (incl the MAF in this video) Doing this every 4 or 5 yrs whilst doing a service on the car when you change the spark plugs is a good thing,as you won''t forget to do it all in one go.This is what i do...never had an issue on my 2002 Yaris in 12 yrs of ownership.Don't use cheap supermarket petrol is another strong advice,95% of the time i use Bp,Shell or Esso.
Hello Peter,
When I start my Toyota Vios(2007) w/ 1.3 VVT-i engine, it starts with 2500-3000revs. After about 2 minutes, it will go down to 1000revs. Is there any problem in my car?
Change the intake manifold gasket trust me
Hello, thanks for your video. One question, I have a 2008 Toyota Corolla with 230,000 km of manual gearbox, 1.8-liter engine, type 1ZZ-FE. The fault is that when you turn it on it starts with 1300 rpm and as it warms up it goes up to 2000, that is, it does the opposite since I understand it should go down to about 900 rpm. and when I'm hot I go out and when I make the gear changes I see that the rpm oscillates between 2000 and 1000 rpm and when I continue the march the minimum is 2000 rpm. If I leave it running stopped the car stays at 2000 rpm. I clarify that with a scanner it does not give an error. Well, we took out the carburetor, total cleaning including the MAF sensor of the filter, I clarify that you cannot take out the IAC valve to clean but the carburetor body was immersed in non-abrasive remover liquids and a lot of dirt came out. We measured TPS and IAC with a multimeter, simulated with power and everything was fine. We checked the pipes that had never been touched and were spotless. We put everything together and it starts doing the same fault. Then I disconnected the EGR vacuum valve and there the rpm's dropped a little but after five seconds it accelerates and when connected it returns to 2000 rpm. The same if I disconnect the PCV valve and it idles at 200 rpm until it shuts off. Could it be a fault in the EGR vacuum valve or Crankshaft Sensor and cams (CKP and CMP)?
Hi did you get it resolved...I'm experiencing the problem, I have a 2002 1.8l toyota corolla.
Hi, the issue is inside in Throttle body. You must replace that part👍

Today..i and my wife struggling in d middle of traffic jam..with 38deg c..sweating..
Found your video..do exactly as you did..and the car idling ok..its was the sensor dirty..thank you for tour videi..that make someone there life much more easier..thank you
This week my corolla started acting weird.
Cold start : 2200 rpm
After less than 1 minute, it started jumping between 600 and zero (!) rpm
I cleaned the mass air flow sensor like you did,disconnected the battery for 10mins and it seems fixed now!
Thanks, keep up the good work ;)
pbasses Great work ! And thanks for info.
Peter Finn hello, when i start my tToyotacorolla the km/h jumps to 20km and the car is not moving? how i fix this?
On my 2005 Corolla the idle when cold is steady, but when the engine is warm the idle goes up and down between 600 rpm and 1000 rpm. This makes it tricky to handle at stop lights as it will stall if you don't give it gas, and when you do give it gas it's hatd not to give it a bit too much gas, making it seem like you're a noob or an old lady.
👍 Noted
@@PeterFinnTheCarDoctor Do you think I need the same fix? It seems that it only goes down too low (600 rpm) when the engine fan goes on. 🤔
I have issue with my altis 2000, during iddle on the traffic jam, rpm drop almost to the lowest number than when i press the gas pedal to go forward there is no respond at all for few seconds, could you advice how to solve it please!
Hi, maybe your engine is so worn out
I bought a 2003 Toyota Yaris Verso a few months ago and then realised that when the motor was hot and I turned it off, the engine would not start again. I read and learned about replaing the idle air intake valve and also replaced the MAF sensor. Also a new air filter. But now when I start the car, it revs up to 2000 rpm when it is cold. What have I done wrong? Please help.. I am in Norway where it is so expensive to use a mechanic... Dee
The 2000 rpm issue did not happen before I replaced the MAF and idle control intake valve.
Hi, maybe your throttle body is bad
Try re-learn, remove negative terminal for 60 sec. After that fix it back the negative..
My toyota corolla 2005 ce has 264,878 miles and runs good the only problem is when u stop like in a red light the car start shaking and goes to 800 rpm but driving the car dont do that
But the only way the car dont shake when u stop is when u have the ac higher and the fan is always on and stays on 900 rpm with ac
What can i do ? My husband does the proper maintenance every 3,000 or sometimes less then 3,000 no lights on
Hi, maybe your engine is so worn out. Maybe throttle body replace could help
Okay i tell my husband so we can change the part , and that problem is bad for my car or what could happend?
Yes, you might need a engine replace or new piston rings. Sorry.
Try changing you fuel injectors cuz it's clogged up so the gas can't combust in the cylinder that's why it's causing to act up like that
Check the moter mound's because they might be hard and cracked from age and above idle it'll have no vibration and maybe get some injector cleaner and put it in the tank and that should fix it
Hello Mr. Peter. I have 2005 year Avensis with 1.8 VVT-i engine and I have had many problems caused by abs sensor. Now I have fixed that and now when I stop the car the idle drops to 600 rpm and goes back to normal after few seconds. It keeps doing that again and again every time I stop the car. I have checked the mass airflow sensor, although it's kinda new. Do you have any ideas what would be causing the problem? Thanks.
Hi, your engine compression might be low or throttle body could be stuck.
@@PeterFinnTheCarDoctor okay thanks a lot. I got the fault codes and it gave me codes P0171, P0174, P0133 for every cylinder and also C1246 & C1201 for braking/ABS-system. I'll check every other ABS-sensors, measure engine compression and clean the throttle body. After that I let you know if I have solved the problems.
I have a 2005 Toyota Corolla my issue is after the engine warms up my RPM goes to below 1000 at a red light but it is not stable; the issue is it seams like it will stall the engine but there is no check engine light. if I rev-up the engine to be over 1000 RPM then it's ok. i know there is an issue but how don't I know exactly what it is? This is only when the engine is warm and at low rpm like idling at a red after it warms up it's ok... any help would be appreciated. thank-you
You may need to check the overall tuning of the engine
Hi Mr. Peter, how to fix my Toyota Altis 2013 model, the rpm is getting high when i press the pedal cluth for gear changing. Thank you.
Really? Please take video and send link to me. Ok ?
Same problem..mr. Elbert your problem is solved or not..if already solved please explain me what is the exact solution.. Thanks God bless you

Haii Peter, thank you for explaining how this works. I do really like the way you show every step to take, use simple words. Much appreciated.
Can you tell me if this film can be used for the Avensis Verso 2004 VVTi engine, like you other movies?
And can you tell me where I can find the park assist computer for parking distance sounds? I want to put one in and put sensors on it.
Thank you once more!
Afwijkende Factor Hello. These films works also Avensis Verso.
What is the cause of the RPM decreasing in a fluctuating manner when I take my foot off the gas in first gear? (I have already cleaned the throttle body.)

Hello Peter! I`m from argentina, I have a corolla xei vvt-i 1.8 engine 1zz 2005, i got a trouble and i will comment to you, maybe you can help me, when i accelerate i feel a cut in the acceleration like if one cylinder fails and i see a oil consumtion and smell of bruning oil.
before an inspection i have find the distribution lock broken an i was think "the cause of il consumtion" but not.. i changed it and the oil consumtion remains.
I was make a cylinder compression test and its ok, a throttle body clean, tps sensor test ok, MAF test ok,
I was not do a obd2 scann yet
thats probably can be a coil? How can i test them?
I follow you and yours vids are a good help !
Thanks!!! Juan
Hi, you could test your coil using obd scanner. Look my video: th-cam.com/video/Ah2ysLIHlw8/w-d-xo.html

would this method work on 2000 Lexus ES 300? BUT I am suspecting more sensor Issues cam sensor and IAC.
Yes, it should work too.
Will this fix issues with the Valvematic system??? Recently had the check engine light come on, following which scan codes p1047 and p264a came up. Overall, been experiencing issues with rough idle/speed cuts, laziness and car shutting off during traffic stops.
Yes. Thanks for watching!👍😊

Hi Peter, can u please assist. I have a Toyota Corolla professional 1.4 4zz. I have replaced my cylinder head and installed new oil pump and new cams and timing chain kit. When it starts it's fine, no noise. But after about 10 minutes the check engine light comes on again and also the low oil pressure sign shows. The water level is fine, and also the oil still looks clear. The idling is bad and I don't know what could be the problem anymore. It is the 2nd time since last year that I have replaced the cylinder head. Can u please help me
Hi, you have maybe cracks in cylinder head or block?

Hi Mr Finn! I have a one year old corolla 1.6 L 1Zr-fe engine. Rarely when I start the car from a cold start, there is a loud rattle which lasts a few seconds. I have googled this and some people say it is a problem with with the intake VVT-i gear which must be change. Is this true? Grateful to have your expert views on this.
This sound is normal and your car is OK. The oil pressure becomes high in engine and valve caps makes the sound. This is normal and no issue in engine. :-)

Peter, i want to ask a question about engine vibration.
I have a 2009 Camry with 2AZFE ENGINE, 2.4L. 215,000 miles.
When i am stopped at a light, and the engine is in gear, i get a noticeable vibration. If i shift to neutral, it goes away or is much better.
I have the following new parts i installed trying to fix the vibration.
New Toyota OEM motor mounts, all 4.
New spark plugs
New alternator, Denso
New water pump.
New serpentine belt
New coil packs, all 4, Denso.
New coil pack connectors, Denso, all 4.
New valve cover gasket
New intake manifold gasket
Newer AC compressor. Has 71,000 miles on it. AC works good.
I think the engine is being loaded down when in the drive gear. Engine rpm us 750-850 when idling.
Gave you seen this?
Engine runs good when driving.
Thanks!

Hi, please visit the Toyota Dealer center.
stops suddenly? explain. do you mean the vehicle will be in motion and decelerate without braking to a stop on its own? do you mean the engine turns off while you're stopped? I have 2011 yaris, manual transmission, but haven't experienced what you described before.

I have a G corolla 2001 auto transmission car, when I start the car first time after a period (usually more than 10-12 hours) the car starts and immediately rpm drops and stop the engine. This happens even in the evening and night. After couple of times starting and pressing accelerator (providing gas) for couple of minutes it works fine. Once it is started it has no problems of starting and stopping it again and again. When I press the brakes while driving and the car is near to stop it starts shaking a lot till it is accelerated to a speed of 20 KM/hour. The problem is more if AC is on. Can you help me in this regards?
Hi, your engine looks like old and weak. So, turn off A/C and if issues are still, replace the engine.

OK so Peter, I'm just having a hard time understanding your accent at the beginning. Did you say a NORMAL idle speed when starting the engine cold is around 1100 rpm, and a warm idle speed is around 800rpm? I think my idle speed is around those turns when my engine is cold/warm. I notice my car shakes when I'm stopped at a red light. Do you think this is due to the worn out motor mounts OR idle speed issues?
Hi, normal warm idle is about 800 rpm and normal cold idle about 1200 rpm. Thanks, Sir. :-)
Peter Finn mine is vitz 01 990cc normal cold idle is 600 rpm to 800 rpm till warm idle is 1000 rpm...and when i put gear on neutral which is manuel the idle keep going up and down from 600 rpm to 1600 rpm ...if you could help please thanks you
Hi Peter I have a 2004 toyota corolla 1.4 vvti. My problem is after driving for a while at speeds like 120kph the idle gets a little crazy and bounces up and down. What could this be? Really appreciate if you reply.

+Igor Nirca Dirty Idle Control Valve sensor causes this issue over 90% at a time. Have the ICV sensor cleaned. Also, it is wise to clean the air flow sensor for better fuel economy and quicker acceleration. I have had the same issue with my 2007 Camry. Take care of it ASAP, because in a long run, it will damage your car's alternator and shorten the life of your car's battery. At 500 RPM the alternator may not produce enough electricity to run everything in your car.
+kourosh tari Thanks for info
Do you have an online resource where you get your gaskets from?
Rockauto has very good prices compared to the big chains
That's awesome nice and clear
Thank you too 👍
hi Peter Finn
Thank you for your video.. I want to know did you mean that this air leak causes a bad idle speed in cold temperature & then become a normal idle speed in normal operating temperature? OR it causes a normal idle speed in cold temperature & a bad idle speed in normal temperature?
I want to tell you my problem in my Corolla 2011 1.8L the problem once I turn on the car in the morning it runs smoothly with 1600 RPM idle speed, then it decreases to 620 in normal temperature which causes vibrating in engine, this vibrating increases when i stop at a traffic light & the RPM decreases slowly to 600 then 550 then 500, i should move the gear pad to N instead of D to decrease the vibrating little, same thing happening in R, when I try to park my car & put it to R with some breaks it vibrates also and i feel it when i set on chair, I should press fuel pedal to remove the vibrating, the crazy & not understandable thing that when I turn on AC, the RPM increases too much to reach near 1000 RPM & the vibrating goes away, there is no any vibrating in the engine, what the hell is that?? I searched & spent a lot about it, I CHANGED: (spark plugs - fuel pump - throttle body - air mass flow sensor - coils) all parts are new from Toyota dealer.. I cleaned injectors by a mechanic handy..
I need a professional mechanics to advise me for any solution or possibilities of this,, Thank You & best regards..
+Noor Isleem Hi, please visit with Toyota dealer service. They helps.
+Peter Finn thanks but they are not easy in my country.. I took the car last weekend to a mechanic & changes the gasket, it was not broken but the mechanic told it is weak & cause some leak, i changed it with a new one but the vibration still exist.. do you know some possibilities t check? even if you are not sure its ok i will accept your suggestions.. thanks
The reason people watch people like you who know a fraction of what needs to be done right with computer scan tools is the stealership charges $140 + when they can get misinformation for free like I did and it cost me a lot to fix my car right there are too many mistakes in your videos that are not even logical like you make it up cause you dont have a clue invest in factory manuals top of the line equipment Dealers dont answer the phone if you want free info where I live please stop making videos and go to wyotech and give youtube back there money there paying you
Hi guys I had the issue when I turned on my Toyota hilux it's not pick up the speed it going slowly, what can I do
Clean the throttle body.I would remove,clean or replace the PCV also as doing all 3 of there (incl the MAF in this video) Doing this every 4 or 5 yrs whilst doing a service on the car when you change the spark plugs is a good thing,as you won''t forget to do it all in one go.This is what i do...never had an issue on my 2002 Yaris in 12 yrs of ownership.Don't use cheap supermarket petrol is another strong advice,95% of the time i use Bp,Shell or Esso.
nice video. Now i can do it myself and save money.. thanks
Great work !
Hello Peter, I have a 2014 Corolla S manual, the idle rpm is too low (600) causing it to stall frequently driving away in 1st gear. I would like to bring it up to 900 rpm. The gas pedal is electronically controlled. How do I raise the rpm? Thanks! Your videos were very informative but not relevant to our situation because it is electronic.
+Ingrid H Hi, please do this service. Look my two videos: th-cam.com/video/dTlTbgKzO9w/w-d-xo.html and th-cam.com/video/cnuqxDDbFrQ/w-d-xo.html
Hi Peter and all People,
In First of all I'd like to say good job with your channel, keep it going!
And ask you about my 1.6vvti 124HP Auris 2007.
Got RPMs hesitating at 0km/h, its like between 450rpm to 850rpm. And RPMs are hesitating while I'm driving too. Nearly noticeable but about +/- 50rpm.
Fast deaf cranky noises when the gas pedal touches floor (in this time I got 2500rpms+, and 3-5gear).
- I changed spark plugs already. One of the old one has white cover.
Rest of them between black and brown,
- Cleaned MAF,
Ah almost forgot. ECU doesnt illuminate "check engine". Computer said "no error codes".
Im thinking about "knock sensor" and timing chain.
Will you help me?
Regards Maciej
Hi, your car needs new piston rings.
@@PeterFinnTheCarDoctor I think you are wrong. The car is not smoking from exhaust. Not at all.
How much did all the parts cost?
moro corollassa 1.6 vvti 2005 sellainen vika, että lämpimän koneen tyhjänkäynti laskee jonnekin noin 500-600 sitten nousee ylös jonnekin 1000-1100 ja seilaa tätä väliä? missäköhän vika

Hope you service it regulary?

I had a p0016 code on my 2011 corolla because because it was outta time on the timing chain by 2 teeth! That’s what I was told by a mechanic! He then went to fix my car and he charged me 450$! Afterwards I go to drive the car AFTER he said he fixed it! And now it’s throwing the same p0016 code and a p0015 and p0017!?! As soon as I drive off his parking lot! I’m so pissed off about this! I immediately turn around and let him know! He said he will continue to work on it at no extra cost! I don’t what to do at this point!?! Should I let him or ask for my money back?
Please ask discount.
Peter Finn he seems like the type that’d just say no and mess my car up even more or something. I wish I lived around you man!
how did it turn out?
Can I use petrol to clean?
Yes, Sir

Im having the same issue, did your car get fixed?
Please I don’t know how to put the srotor puppies
Thanks for comment 👍😀
you do know that the idle should drop to 600-700 rpm when the engine is at operating temperature (at least acording to autodata and my local toyota dealers).
+eivis13 Yes, it drop down when warm. :-)
Peter , what did you do to clean the sensor ?
