I have a Lexus CT, which is the same engine system as Prius. I was depressed with the engine vibration for the last couple of years. I brought the car to multiple dealers, and they replaced plugs, battery, tires, etc, charging me many $k. Then I found this video. I followed the instructions, and the vibration is gone. You saved my life!!

You have to also pull your intake and clean the 4 egr inlet holes that flow into the intake really good... You can instal brand new egr valve and cooler but if those 4 holes are blocked car will still not run correct

I don’t even have a Prius and I still found this entertaining to watch. I like how he managed to do this, not drop a bolt or yell out a curse.

I have a beautiful Prius. in just half a million miles. very clean and quiet. I only do 200 miles deliveryx a day. there is no problem at all. no oil reduction. greetings from boston

Your camera positioning is perfect. Makes your videos very easy to watch and figure out what your looking at.

Just did it on my 2010 Prius (150K+ miles). A few notes: 1. There's no real need to unclip the plastic bracket, just move it out of the way. 2. Absolutely no need for a bronze brush and the drill. Blast that pipe with throttle body / carb cleaner, and it's shiny as new. 3. Wrap a piece of lint free cloth on a stick and saturate it with carb cleaner. Wipe the corresponding manifold & valve holes with it, rinsing with a stream of carb cleaner after each insertion. Basically same technique as removing the ear wax: don't push it in )

Had the egr code on my Prius.. this video helped and saved me over $200 bill. Thank you very much

Thanks for doing this video. Dealer wanted over $300 (estimate), followed your video and did it myself. Note: didn't remove the plastic tab next to left port/tube, just pushed it aside. Vehicle seems to run better after it was done. Thanks again. cr from Florida

Thank you so very much! I followed your video step by step and it resolved the issue and the engine warning light is now off and saved me time and $$. You're awesome!

Really helpful video, I had a noisy engine and juddering at idle on a Lexus CT (same engine). I did find in the end it was the spring on top of the EGR valve that was jammed open causing the problem, lubricated it and gave it a work up and down to free it off. But did give the pipe in the video a clean at the same time I had plenty of crap inside also.

Just did this, your instructions were great. Thank you. 2012 plug-in Prius with 175,000 miles.

Amazing,this dude definitely deserved millions of subscriber.god bless you Bro.

I love your prius videos. You are helping me out so much. Thanks!

Thanks for the video. Did this on mine with 90k. It def needed it. A few notes for others. I was unable to get the mas connector off, but there's enough slack to move it out of the way safely. Second i didnt have a small opened end metic wrench set. But i was able to get my 1/4 10mm socket in between the harness wires to remove the front 2 bolts holding the pipe

I'm glad you have all these egr cleaning videos. I just bought a 2012 with 186k on it and I don't think the EGR has been cleaned out. Would be a very good idea to clean the cooler too while I'm at it. I'll probably soak it all in the sun to try and get it broken up.

I went beyond and took out the entire EGR assembly/cooler to clean. I used an extra reach 12 mm racheting wrench for the three nuts in the back and slowly reached the 4th HIDDEN 12 mm nut underneath the EGR cooler (with another tool). Used a Torx E8 socket for the two long bolts in the back of EGR cooler. Good video NAB!

Hey thanks so much for this video. I hope that you become extreamly popular on youtube

Thanks! Engine light went off a day later after watching your video, great instructions!

Great video! Thanks I owe you a very large beer when you are in San Diego

I did this on my 2010 Prius with 116k miles and I removed the intake manifold. I was glad I did because all 4 runners were gross. I highly recommend taking off the intake manifold. It wasn't that hard to do. I also installed a new PCV valve with it off and an oil catch can to keep it cleaner down the road.

Next time try letting the pipe soak in parts cleaner for a while, if you're not in a hury. Also, use some vinyl gloves or something. Those chemicals are harsh. Good job.

I haven't done this job, but it looks like if you passed a rope through the pipe/tube and pulled it back and forth with solvent on it, it could clean the middle of the pipe that you couldn't get to,

You are supposed to remove the intake and clean the 4 small egr holes and install a catch can on you pcv to catch all the oil blow by...

Great video! I found your explanation and video easy to follow. Now I just need to find the time to clean out my EGR pipe!

2012 Prius with 295k, Toyota dealership quoted me $1700 for this along with cleaning the intake manifold, throttle body, and replacing spark plugs and gas cap. I’ll be doing it myself.

Tips to PREVENT HEAD GASKET FAILURE: 231K - 2013 Prius. Just had head gasket replaced for $1,500. Could of prevented it if I cleaned/replaced EGR cooler around my second run of 80K or 90K miles? Maybe it happened to me a bit sooner because I cleaned my EGR cooler out about 90% +\- at 130k miles, + 1000 miles/week, 50K/yr. and maybe because of potentially more cold/heat cycles on the head gasket. Lots of people highly recommend 3rd gen prius owners clean or replace EGR cooler AT or BEFORE you hit every 100K miles. EGR cooler $178 new on ebay, $300 at toyota, part 25601-37010. Clean EGR pipe and valve with the intake manifold/throttle body. Replace PCV valve, optional oil catch can. X At 230K miles my EGR cooler was completely blocked up with soot (previous cleaning at 130K). My symptoms were brief misfire on #2 couple times every 100 miles and slow engine coolant leak into the engine. #2 spark plug and #2 set of 4 valves were pretty dirty. Head gasket and cylinder head was replaced with refurbished one. (6,000/3month warranty). Car runs great so far. 4th Gen Prius has improved this problem.

well organized. reminds me of military instruction at its finest..

Unfortunately, that won't clear a P0401 code, in most cases. However, it is helpful to clean the pipe out. Here's what I did to correct the restricted flow problem. When you pull he plastic cover off of the top of the engine, you'll see the round (nipple-like) cover to the EGR solenoid. Remove the two Phillips head screws and pull the cover off, no need to disconnect the wiring harness. Unscrew the cylindrical magnet with the bearing on top. The shaft will be exposed. If you put a washer over the shaft, just covering the round disk, then screw the magnet back on, this increases the throw of the plunger, and restores the flow. If you look inside the cover, you'll see a small plastic ridge, it's covered with grease. Look closely and you'll see that it's worn down and not letting the valve open like it should, or used to. This is what fixed mine, and I just wanted to save headaches for others. It will take three run cycles to clear the code. You just saved some cash...HAPPY DANCE ! ! !

did mine at 56K it was dirty. I cleaned the manifold as well. easy.

he really nicely explain

after cleaning egr valve, cooler, pipe and intake manifold, gas mileage on my 2013 Auris TS dramatically increased. Especially egr cooler was full of black carbon that took several degreaser baths to wash away.

What made you clean this EGR pipe, engine is running poorly or some warning lights went on, or bc you have high mileage on the engine then decided to clean?

Why do I get the sense that NutsAboutBolts would make a great landscape artist? 🤔

Thank you very much. I don’t know if I can gather the courage to do that. I’ll bet I’ll forget to put a part back

Will doing this , will is stop my 2012 prius engine from sounding like it wants to blow up?

The proper way to clean is to take manifold out and clean 4 ports which are normally clogged.

Anyone try running prius without EGR pipes?

Thank you so much For this video! You are a great mechanic!

Great video; just bought a '13 with 67K miles. I will look into doing this. I like your other videos also. Already changed the CVT fluid to synthetic recommended by PriusChat. The original stuff looked dirty although the dealer said wait until 100K miles. Why wait? Preventative maintenance is the key to long life. The car seems to shift a bit better also. Keep up the good work!

What tools do we need in order to take out the EGR valve? Can you link them please. Toyota Prius 2010

You forgot to clip in the tubing around your filter into the 3 clips FYI lol but still a very helpful Video thank you.

Excellent

Thanks this video is so helpful and useful

I have 120k on my 2013, will cleaning the egr pipe prevent the P0401 code?

What size are the bolts that hold the pipe on? at 6:07 Im missing the lower one

What is the point just cleaning out the egr pipe

On my 2010 prius when the battery is low and at low speed acceleration (10-15%) there is a rattling sound. This only occurs when the battery is low and the engine is running to charge the battery. I read online that this could be due to a dirty EGR. What do you think? Dealer says its a bad hybrid battery and to trade the car in. I really don't think it's the actual battery.

я сегодня помыл) пробег 122ткм по японии было грязно,но не сильно)

Did anyone’s Prius shake at start up for approx 10sec prior to this???

Thank you very much for asking for this black one that you put on?

So is this preventative maintenance then? Do this to avoid future headaches?

How do I know if this needs to be cleaned? My Prius runs fine, but gas mileage is not where it should be.

Better wear eye protection when spraying brake cleaner. Get some in your eyes and you will holler out loud. Gloves to for spraying in your hand. OR, a better way to clean that pipe is soak it in Diesel. WAY less fumes and costs much less than canned death. Keep a gallon of Diesel in the garage to clean dirty filthy parts just like yours in the video.

Hi NutzAboutBolts, I watched a fews of your videos and read your maintain guide on priuschat; however, I have not seen anyone mention that the high voltage battery was disconnected before fixing. I assume that’s a must, correct?

How so small amount of dirt is causing problem?

Perfekt work

Awesome tutorial. Thanks!

Hi, were you getting a violent shaking when you turned the car on? I did, I also noticed that there was no oil. I added oil and same issue. Thanks

wow thanks for sharing

Any idea what would cause it to fill up often? My girlfriends car packs this egr pipe full once a year

and what this video is about, you only cleaned one pipe? how about intake manifold, throttle body, EGR valve?

Awesome video. Does the Rav4 Hybrid require the same procedure? If so, please post a video showing the location.

The Toyota Prius Aqua is different. Can we do the same process on it? I think the egr pipe of the Prius Aqua is on top of the ignition coils.

Thanks for this excellent video! I am going to try cleaning the EGR as you did here. I drive a 2013 Prius w 197,000 miles. I'm wondering if there is any chance a fuel filter can cause the engine to idle roughly? I don't know if my fuel filter has ever been replaced and I used some old gas recently. I don't see much about people replacing fuel filters on Priuses.

I'm getting a P219a code on my Prius V with 120k miles. Should I try this before cleaning the whole EGR and cooler?

Hey NAB, thank you for your videos. Last night my 2010 Prius started sputtering at low RPM. I also noticed a sulfur smell. I had never seen that before. The temperature is getting colder in Chicago too. When I drive at higher speeds, it drives normal. Any idea? No engine check light.

Thanks!

I have a 2014 prius i have a p3190 (low engine performance). Driving me crazy.. Car dies and all the lights come on. After i let it sit for a hour it starts. Tried cleaning maf sensor n throttle body so far. My 12v battery is at 12.2v

this can cause gasket engine blow if don't clean?

How do you know if your erg valve needs replacing just a clean??

Upload some videos damn it, its summer LOL

How often should it be cleaned?

Can this EGR pipe cause by bubles in the reservoir?

Really good video, thanks

Does the dealers not do this service I have 105k miles on my 2013 prius. Should I do this? Whats that cleaner your used called?

Is there a reason why I should do this steps on my Prius 2015 with 40k odo on it?

Good video thanks

After cleaning I experienced misfiring. Disconnected and reconnected coil one now it was running well for a week and now I have four codes after a week. I do get a rattle at times I wish I knew of this process before 150k. Codes are p0351 p0401 p3190 p0a0f c1241. I don’t really want to pay the dealer to fix but I think my next best step is to check coil one.

Thanks it was very useful

Great video. I just did mine. Forgot to plug electric connector into egr valve completely now I have an archived p0403. Anyone know how to clear it? Thanks.

Hi bro can I ask something about hybrid vehicle if the vehicle is on mantinance mode then we can drive it or not if yes then its safe for us and also for vheicle

Hello there. I have the same issue could you help me? It's been shaking on and off at cold startup for around a month or so but I just got a p0300 p0301 p0302 etc code today with an engine light. Drives fine otherwise. just on startup. (backround info. my water pump just went bad about a month ago and this happen roughly around the same time. 147k. don't know if it's related! not losing coolant though. levels are good) A couple videos were saying that means it's 100% a bad head gasket. But is that true? Or should I try the ERG, and also replacing the plugs / coils (they need to be replaced anyway). I do find it funny that ALL the cylinders are showing a misfire all at once...

Can I use this for the 4th gen?

Great videos. Would you ever put a "oil catch can" on your prius? Would it effect the "computer"?

Do you know after how many miles would be a good time to do this? Also I saw your Fan Cleaning video Every how often should I do that ? Thanks

Hello friend did you help me with the code P0353 and the coil are oem new and the spark plug, its a 2010 prius

How often should you clean the EGR valves and tubes? Every 80k miles?

Would you recommend changing the pvc valve at this egg cleaning also?

I loved your videos and have certainly bought off your Amazon referral links. I am wondering if you would have insight on this… I recently did the EGR clean out, the pipe, the ugh radiator cooler looking thing, and the EGR valve too. Everything reassembled and car runs like new. So much more power. And check engine light never came back on. But now I am smelling exhaust when I am driving close to a truck or whatever. Doesn’t matter if my car is on recirculating air or fresh air, it comes in. But if I am not driving next to a smelly truck, I don’t get smell. So smell is not coming from the Prius. Any idea what step I could have missed in the reassembly that could have caused the recirculating air to still be pulling in outside air?

my dear friend all the knocking problem and noice problem I could remove it. Simple solution is that don't even open the whole EGR kit. just open the two screws of EGR socket and check is your EGR moving up and down. if it is not then all the problem in GEN 3 Prius is due to this EGR. I can send you detailed solution trust me I was banging my head to all the dealers and eventually I could diagnose and rectify the problem. now my Prius is running like a queen.

Very helpful

Thanks You.

You were half way there cleaning the EGR system. Very important to clean out the entire cooler too.

Is this job even worth doing if you dont clean the EGR cooler, valve, and intake manifold as well? I presume if the pipe is clogged the other elements are clogged?

hey bro were are u located?

What's average time to disassemble, clean pipe and reinstall?

A+ video.

2010 Prius egr information CRITICAL! If you have e code for restricted egr flow, here's what to do. Seriously, I've done this in parking lots in under two minutes! Pop off the plastic engine cover, and see the egr valve on the right side. Unclip the wire harness, remove the two Phillips screws, and pull off the cover. Rotate the cylinder counter-clockwise and pull it off. Now, find a lock-washer that fits over the shaft, and clears the spring. Slide it onto the shaft and reassemble. Here's why, if you want to know. There's a plastic hub that gets worn down inside of the cylinder and, over time, won't engage the plunger enough to recirculate the exhaust gases. The lock-washer acts as a shim and gets it working again. Allow 5 or so engine cycles (cool to warm, and back again) for the light to reset. Now, punch it! It runs WAY better! Now, use ashtrays, don't beep your car to lock it, and smile more!

Hi NutzAboutBolts, please excuse me for a rather back-to-basics question here: what would the effect be of not cleaning this EGR pipe and its associated ports? What aspect of engine performance would this affect, and by how much, in general, would you say, in your experience?

I did this and it didn’t resolve the issue. Unfortunately I think the intake manifold has to be cleaned completely in my situation :/
