2006-2012 Rav4: Throttle Body, Intake, MAF, & Injector Service 

Hey Jack. Checking in 4 years after this video was posted to thank you very much. I just completed this service and it runs beautifully. 🙏

This was clear, sharp and down to the point with no extra lecture . Thank you 🙏

I just did this to my 2010 Rav4 V6 with 154K miles. It runs super good now. Thanks for your tips.

All I can say is wow!!!! What a difference..thank you

I did the 100k tune up plugs wires etc etc and it was still chugging at startup, running like garbage so I decided to try this next. IT WORKED! I cleaned the throttle body out, did about 80mph on I95 for about 3 miles or and now the Rav4 runs great with smooth startup. Thank you very much!!!!

Thank You! Really appreciate the video, the content you shared, and the precise manner you shared it, good visuals and information. I followed your directions step by step which resulted in clearing up problem I was having with slow idle almost to a stall when stopped at traffic lights or stop signs. I gave a thumbs up and subscribed. 2008 Rav 4, 4 cylinder with 233.000 miles on it. Muchas Gracious!

This is better than reading the repair manual.....thanks a bunch!

Great video! Love these kind of maintenance videos. You sure know what you are doing 👍

Thanks, Jack! I replaced the plugs, PCV, air filter, and cleaned the MAF and throttle plate today. 2008 Rav4 with 98k. Runs like new now, idle and throttle response is nice and crisp. I appreciate the time you took to make the video!

Once again MJ thank you. Our 08 Rav4 213000 miles never touched throttle body, intake, MAF, & Injectors. Only added some Sea Foam occasionally to fuel system.

I'm working on my daughter's Rav4 2006 that's running very poorly. She got a new Corolla but will sell the Rav4. this video will be very helpful. I replaced plugs / coil. Improved but still not ok. Thanks for the video.

MasterJacks, to clean the MAF properly, just take out the two screws and then spray with throttle body cleaner. Also let it dry completely b4 starting engine.

i just spent $300 dollars and a month erase 4 codes this man is 100% correct

I just took my 2016 Rav 4 with 35000 miles for its last free oil change at the Toyota dealer where I bought it new and tire rotation and balance on 2/8/21. It is now out of its warranty now. In about 15 minute they come to me and tell me that they have done a free inspection and have looked at and found that my throttle body is all sooted up and the injectors are clogged and need cleaning. I ask how much, it is $220 for one and $115 for the other. So I tell them thanks for letting me know and I would take care of the problem when I get it home myself. They say it will be finished just as soon as they run it through the car wash. Stopped on the way home and got a can of throttle body cleaner and injector cleaner to add to the gas. Got home, popped the hood, removed everything to get to the throttle body on the back side of the engine, could not see where any of it had been removed to inspect it where they could tell it was sooted up. The throttle body was clean as it could be. I put it all back together, put the can of cleaner in my shop unopened and the next time I fill up with gas I will add the bottle of injector cleaner to it. The car engine runs like new so I will write this off to them trying to up sell me their service. This is the reason I do not like taking my cars in because of all the Bull Sht up selling they try to do.

Have the same car with 230,000 miles and still going strong.

- If changing spark plugs do it after all this operation, oil also. And wash/ clean the motor area prior. While reving the engine and adding Seafoam, you can turn the key off and carefully add a little raw Seafoam to finish, and the remaining revs/ vacuum will pull it in, coating the insides. Just let it soak the valves, piston head, and chamber a few hours. Better chance the carbon may release/ come loose later. May need a little starter fluid on restart. Good Video. Thx

Great video Informative I have a 2008 rav an I only clean the throttle body .really appreciate the vedio

Please put out more rav4 content...

Cool thanks, good video for ASMR also.

Excellent. Thanks.

thanks for your video !

Thanks so much!

Thanks much appreciated!

Thanks so much good sir!

Thank you for the info. I had a successful servicing of my Throttle Body, Intake MAF

Wow..if you keep at it like this,your car will last you 1Million miles,at least!....I like your videos man,I am subscribing right now,just for the extra knowledge of course,I do most of my car's maintanance but tire related stuff,just don't have the tools,thanks for posting.

Iam going to do just that,while under lockdown. 😷

Thanks for the info !!!!!!!

Wow i cleaned the Throttle body as much as i can but it was soo uncomfortable im a women 5’4 tall..i didnt stick my hand inside the left side of the throttle body i didnt remember that part of the video..also cleaned the air mass flow sensor..i cant believe it what a different!.. the car respond and drive faster, the throttle looks like it was never cleaned before, it was hard for me but IT WORKED !!...the car with 165k miles felt like trash like a 200k some miles but after this it fell like it has a lot of life left..

Wow 😮learned a lot

Thx for the video, I just subscribed

I never had a problem cleaning electronic throttle bodies except on nissans. Always disconnect the battery before cleaning any electronic throttle body

Thank you

Thanks!

Can you help me with how to resolve a system too rich?

I like to wipe off my hose connections with a soapy warm used up micro fiber towel, and then liberally use SIL-GLIDE Silicone brake grease (multi purpose) On the parts to reassemble.

After cleaning the throttle body, the first start up scarred me, it cranked for so long

Thanks 🙏

0:28 there is a rubber hose directly underneath the connector. Do you know the name of the hose or the name of the sensor that was disconnected?

For the next generation Rav4 after this, does that lower hose @4:10 pretty much do the same thing and go back to the intake manifold? It's so tight back there to see where the hoses are going. 😂

The first start up took a few cranks. When it finally turned on it looked like it wants to shut off. The lights were dimming.

Currently have a 2008 rav4 with 182,279 miles on the ODO. And idles super low to 500rpms and shakes hard as hell but goes away. But I’ve noticed that at times it would be related to my AC when I had it blasting and cranked up high. But when I turned it down it would stop shaking. With that said, im going to do exactly what was done In This video and see how it turns out.

How to change throttle body? Actually I need access to intake manifold control valve actuator, so I guess to take it out , need take out throttle body

Change brake pads of rav4?

What fuel or liquid used in fuel tank and in injector ?

Thanks for making this video. I have the same color 2006 RAV4, in a 4 cylinder as well. Just performed the throttle body cleaning on it and I think I solved an engine shuddering issue I had (dropping RPM's to 500 right when I slow down to a stop). Just wondering if anyone here has this car? If so, are you experiencing some whirring/humming noises coming from the driveline? Curious to know if you have the steering clunking noise as well? I haven't been able to definitively nail the origin of these problems, wondering if maybe you have... This car has been unstoppable aside from a few non-critical issues. The only downside I can think of is that I don't have the 3.5 V6, those are peppy for being an unassuming crossover.

These Toyota MAF sensors are designed to be removed with the two Philips screws on top. The part you sprayed and cleaned is just the air temp sensor. The actual air flow sensor is concealed and only accessible by removing the sensor from the filter box assy.

I didn't know you could use the intake manifold port to clean past the throttle body with Sea Foam!! I've been buying the Sea Foam Top Engine cleaner with the little straw attachment. Such a pain to use because of the throttle body location which forces me to turn the bottle upside down and just makes a mess. Your way is so much easier!

I just had to replace the EVAP valve in my 08 Rav4 and now I'm getting a lot pf shaking while idling. Would this, in theory, help with that issue or would you recommend what you did with the spark plug video? Thanks for any info

Do you do a V6?

Hi Jack, very helpful videos. I have a Rav 4 2006 4 cylinders and recently replaced the alternator, and the drive belt. Note I disconnected the car battery which I believe reset the ECU. After this I noticed the engine was running rough, which got slightly smoother over the last couple of weeks but was still happening when idling. I then replaced all spark plugs which were quite worn. Now the car runs well except when idling the Revs often drop around 500 thus vibrating the car. Would a throttle body, intake, MAF and Injector service help with this? If not what else would you suggest to do? There is no engine warning light or codes displayed on my OBDII

Hello MJ, I want to clean the fuel injectors of my 2009 RAV4 using OTC fuel injector cleaning kit. It should be connected to the fuel rail. Could you please help me to figure out how to do this. I am an amateur. Thank you in advance.

Will cleaning the throttle body help with the long cranks when engine is warm? I heard yours crank a bit before starting up after the cleaning

Thanks. Is the liquid from Throttle Body Cleaner going inside the butterfly opening. Is that OK?

@master jacks...nice video..does opening the valve from a TB with my fingers damage it?? just wondering i don't really know much i want to clean mine

Hello, if someone could reply that'd be great! Wouldn't that cleaning liquid mix with the gasoline/diesel? I am no mechanic so I figured I'd ask before attempting this :)

How many kilometers do you need before cleaning both the Throttle Body, Intake, MAF?

how do you clean the backside of the throttle body if you don't take it right out?

For the intake, can I pour in water instead?

Also note this generation of Ravs has many owners' complaints of spongy brakes. Once the symptom occurs (often after a brake job) the problem is virtually impossible to fix.

Hi there, great video, car is running much better now. Just one issue I’m having, when I was doing the last part, I did just as you said, had my wife hold the gas at 2500rpm and funneled in just a little bit of sea foam, my check engine, VSC and 4wd light came on and won’t turn off now. Should I be concerned and have it diagnosed? Or should I just try to reset it? Thanks for the help!

did you use the same sea foam for the engine as you did in the gas tank?

Hi after doing the throttle body cleaning and adding seafoam in the fuel tank car ran smoother. However after adding the seafoam to the air intake hose as described, during the process, check engine light, VSC, and 4WD, lights came on dashboard. I drove the car for a few miles, and still on. Any insights?

you sprayed that MAF cleaner and is dripping down moisturizing the filtering net of the air box. I can fee the awfully -toxic smell of the air blowing in the cabin. Did you think a little before doing that?

Do you have to disconnect the battery in order to be able to stick your finger inside the throttle plate, I hear you should not move the plate at all, or is it just a myth?

Could this help with eating a lot of gas because I have a 2008 rav 4 eating a lot of gas

Thanks for sharing.. Did you notice a difference after doing this .. you said it helps clear ruff idle.. did it help ?

Can I use fuel injector cleaner instead?

You must live on a mile long dirt road. Damn that’s a dirty engine bay.

Hey Jack, is throttle body electronic or cable driven? Thanks

Shit... i just did this and now my rav4 2006 automatic 2.4l is idle really high. It is idling at 1.6 rpm?????

Did your 2008 have the 2AZ-FE, 4 cyl engine?

So, mass air flow sensor cleaner cannot be used to clean throttle body as well..?

❤❤😂This engine needs a Shampoo to be fresh 😊

Can I use brake cleaner instead ???

Why didn't you just unplug the maf and take it out to clean it? It'd save the step of taking the box off and opening it and all that. Also, do you really need to disconnect all that to clean the throttle body? Can't you just disconnect the hose and push it out of the way?

I don't think it's a good idea to clean the MAF sensor without disconnecting it or the battery first.

Just a nickel worth of free advice?....I’d keep my engine bay clean, at least prior to opening my throttle body....just sayin...

Seria bom se fosse pelo menos legendado para o português!! Motor sujo !! Dono relachado

Please, I want the food on my face I wanna buy it, but that doesn’t let me know😢
