Toyota Prius Hybrid Engine Rattling, Shaking, Misfiring, No DTCs In The ECU, vehicle Fixed 

Great video this is the only one I found that shows how to remove the EGR without removing the intercooler. Thank you 🙏😁

Very very good video, I love the fact that you put genuine parts 👍👍 keep it up please I am learning from every video that you make thanks alot

Same problem happened to my 2012 Prius. Problems solved after the mechanic replaced the ignition coil and spark plugs.

People are really ridiculous always assuming if it's rattling it's a blown head gasket! When this car misfires, it shakes and rattles. There's all sorts of things that can cause a misfire! An EGR system that isn't working correctly can cause this. If replacing a part such as the EGR valve fixed the rattle then clearly it isn't a blown head gasket. You'll know if it's a blown head gasket because you won't be able to put many more miles on the car before it's just not working at all.

Great job and Great video this is the only one I found that shows the cause of Rattling hybrid engine . Thank you so much

Excellent video

Good job Amigo 👍

Good job

Thanks 🙏

Very good job where about is your base??

The new revised EGR NEED TO BE PROGRAMMED!!! Just do it at the dealership. Also they have an updated intake manifold too. But they have programs that covers either or Both. This is really important!

Great video and detail showing this experience! I've been wanting to remove my EGR as well and pressure wash to clean. That's easier and safer to do from what I read. Restoring potentially the EGR Valve without replacing I've read is more risky being that valve or something screws in and can be an issue with removing and installing alone (though I don't think how you did since didn't remove those philips head screws that I've purchased metric hex head stainless steel to replace when I do) and I forget if is like a screw actuated or electromagnetic... seems like screw, though that might be to adjust. I really do forget. I know I did plan to replace the PCV Valve and intake manifold gaskets when I clean that out as well since seems like the thing to do reading around and asking around. Amazing how these Gen 3's can go so long without maintenance and still get awesome gas mileage. I need to look underneath the plastic pans to see what might be stuck rattling or maybe the exhaust heat shields since somethings making a noise down under and I don't know what else would be otherwise since I don't think it's the break pads yet... sounds with the windows down noticing recently like underneath more passenger side... I think. Amazing how these consume oil as well when you don't replace the PCV Valve. Thanks for sharing sir!

Hi, I know this video is A year old I had the same problem last week. I’m stuck another EGR valve on it and are you Star bolt got 12 min nut and A bolt with a star socket because I have tightened it under do the star, bolt not under do the 12 mil loose The star nut Loosen the 12 mil, then tighten 12 Mii up it’s because is touching the metal and it makes it rattling noise

EARLY GEN 3 HAD A RECALL FOR THE INTAKE MANIFOLD. IT ACTUALLY CAN RUN BACKWARDS FROM A COLD START. TURN OFF QUICKLY WAIT. START AGAIN

You can also remove the elbow off the egr to clean the inside as well that's why the pintle is stuck open most likely dirty inside.

My 2010 Prius does this exact thing when turned on. It happened a few weeks after replacing the spark plugs. Is it a coincidence? Is there a chance its one of the spark plugs? Thanks for the video!

While some of this may be true - I bought a 2012 Prius V brand new - and it would do this with less than 9 miles on the car. No carbon built up, etc. It's a fowled plug - and the "clutch plate" (spring plate) on the engine to electric drive connection rattles due to the uneven firing of the motor. This can happen when you start the engine cold - and shut it off right away - then restart a few moments later. Basically, like when the "choke" would be on - on a carbourated engine. I believe Toyota could tweak the fuel delivery and solve the issue. There are instances - where a blown head gasket will do this too - but again, that's because of coolant in the cylinder causing a misfire condition. I've also noticed - that in the US at least - there isn't much if anything that will turn the check engine light on - on the car. It also will do this when temps are in the 40s with high humidity - (light fog) situations... where the computer delivers "rich" fuel mixture due to ambient air and engine temp cold (choke condition) ... usually - shutting it off, waiting about 30 seconds and restarting will clear the issue - as a little heat accumulates in the intake from the initial start. then the issue goes away.

👍👍

I have a 2011 prius and my EGR, manifold, cooler are heavily gummed up with carbon I ran a tech stream at first it was check hybrid system. I cleaned out the bus because it had heavy corrosion on all the battery cell contacts. I let my car sit for about a month I’m cleaning all this I hope that will resolve my problem?? My car never did the sputtering choke before?? Now it completely turns off the engine and gives me a no engine start code along with check hybrid battery?? Any input is very helpful??

Excellent video, my EGR valve has been making the engine judder for a few years now. I have found removing the black cover on the top with the two philips screws. Lubricating the spring and valve shaft and working it seems to prevent the problem from recurring for 12 months or so. I have got into the habit of lubricating regularly to stop the issue. Not sure if I will get away with doing this for as long as I have the car?

I get it the EGR valve is stuck open. No need to test it 3 ways to Sunday. Install the new one and move on.

So, what happens if u leave that plate u installed to diagnose with on, that blocks exhaust fumes from entering intake manifold? Permanently?

Blows my mind that this thing isn’t throwing any codes for misfire…..

Excellent. Thank u sir. My 2010 prius . Is jerking like its fighting to breathe when the heating is high and full blast for 20 mins. Then sometimes its goes away if i off the heating. You think its EGR value ? If so shall i also buy egr valve PIPE?? Thank you & i have subscribed 🙏🏽

So what exactly causes the egr to clog up like this? Ty

What scanner are you using ?

It can be clearly seen from the video that the cause of the fault is that the thimble in the valve body has not been reset. You only need to open the black plastic box and turn the magnet clockwise to reset the thimble. There is a stepping motor inside.

Now when you're doing that water test take the black cap off and turn the threads lefty loosey I think and it'll close up the valve and water should stop flowing same with the new one when you're showing the new one when you got it before you even show the box you see it's open water's going to go through that how you closed it for the test that you're getting ready to do I don't know You have to take the black cap off to turn the thing down to close

I'm not sure that that plunger is spring loaded If you undo the two Phillips screws and withdraw the black part which is the motor housing then you can spin that thing that stuck open and you will see it thread in and out and open and close when the motor housing is together and it gets a signal it opens and closes that valve according to what the computer tells it to open so maybe you turn the car off and it's just at its last setting when you boot the car up it'll close the valve up or do whatever it does on startup I don't know exactly what the protocol is but mine look just like that I cleaned it up I took the motor housing off I looked for this plastic ramp that gets broken which I couldn't find and I turn the threaded rod in and out to see that it works when it's turned by the motor and it turned very freely put it all back together I'm pretty sure it's working but I have no way of knowing whether it's open or closed I think in text software from Toyota I can see in the freeze frame data but I haven't really looked I know I can see the flow measured in HG of EGR going to the intake manifold

Head gasket problems most likely causing the shaking , Complete egr system should be cleaned once a year as maintenance including intake manifold, Egr valve , Egr cooler, Throttle body, Also need to add a high quality oil catch can to avoid the Egr system clogging again.

Will Lucas fuel additive solve this issue?

Everytime the egr valve is stuck you have to replace it, better to replace the car because of the faulty design

Prius 2006 have EGR??? Reply me

could you please share your shop location?

So what was the problem?

Next time if you saw the valve is stuck you need to clean and flash intercooler and intake manifold and PVC valve 2 please thank you

See even the new EGR valve is open

you r struggling How to explain the mater you don't need to change the valve use WD40 and leave it 20 minutes and take teeth brush and clean it as i did it

The misfire from blown head gasket

Your address?

This guy is correct for the most part but he is wrong in the end. The plunger is stuck open due to the gunk and doesn’t need replacement. It’s needs to be cleaned. There’s nothing much that can go wrong by design unless the solenoid that controls the plunger going in/out malfunctions and needs replacement. Watch the video below before your consider replacing with a new EGR valve. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-BuU7HKITbUI.htmlsi=nlQsXtLIYgjMUJSg
