Nice Video. I did clean the whole EGR cooler and intake manifold few days ago on my Prius V that had 190,000 miles. Thanks for letting me know about the electronics part, that I skipped opening it because the screws were too hard . And I am going to clean EGR system on my other car ( Prius C with 130,000 miles ) which seems to be so easy compared to Prius or Prius V. Even changing the spark plugs on Prius C is so simple. I really appreciate those who designed Prius C to be so simple to fix for DIY guys like me. Even the inverter pump is so open that you can replace it from above easily. Thank you. I subscribed.
Nice video. A couple of questions: 1) Do you need to remove the wiper cowl in order to remove the cooler? 2) Do you have a video of the intake manifold removal and cleaning? I think the EGR passage may get clogged inside the intake manifold.
Taking off the black solenoid cover might be a good idea if you wish to not remove the entire valve. It would enable you to remove only the EGR pipe - and if it is not looking very dirty - you could spray cleaner into the outlet of the valve whilst opening and closing it. If in doubt, however, removing the valve and cleaning it properly will always be the best option, I would guess.
@@kennycharneca1 Just a keen amateur! I just did this on my own car at 100 000 miles, and didn't look dirty enough to make me want to disassemble the valve and heat-exchanger.
I took off black solenoid to clean. Took off entire EGR value for Chem-dip cleaning. Are you supposed to snap the bigger spring back down? Or not? I am getting insufficient flow in EGR a now. (Was not getting code prior to cleaning) Going to try to change how far the spring is snapped down and if that clears it
My EGR was working fine. I always facing problem and getting error code after once I opened it for cleaning. Someone please let me know how to adjust the magnetic rotor of its motor. Is it should be full tight or partially. Guide Please.
Never disassemble an EGR valve as diy, and dont waste your time cleaning it. There is no guarantee if it works again and you will never find out til its too late!!. Toyota recommendation for emission system: Replace intake manifold and EGR valve and clean the EGR cooler. Do it once properly.
Good morning! I like your video and thanks for posting one for the EGR. Question, I heard you mentioning about a new engine for your Prius C. How much did you pay? Also, where did you get it from? Is the née engine still running good? Thanks a lot!!
Thanks for the quick reply. I just cleaned the egr and the intake manifold. Egr wasn’t that bad and manifold as well. No luck. Engine still doing the clapping ta’ ta’ ta’ sound :( no difference noticed after cleaning those two things. I guess a new engine? What website or company did you get it from?
This will not fix the P0401 on a Prius C. How do I know I own a shop have fixed many P0401 and I never waste time cleaning these EGR passages. If you looked at the freeze frame every time it throws a code the EGR is closed at conditions that it is supposed to be opened. It means it never even activate when commanded.
@@Elquenosequeda I can’t tell you since your car is not here. There is no single cause for P0401 and I don’t want you to end up buying a part you don’t need or waste time in a procedure and problem persist. What I can do to help you is share you a hack on how to pass inspection even if your car has a P0401 code. Second I can explain to you how the computer monitor the EGR. 2 things why the hack works. 1) the code only sets on the 2nd drive cycle.2) you can pass inspection with a minimum on one criteria that is not ready yet. This means for it to work you must not have any other codes, So to pass inspection here is how you do it. Clear the code then do a drive cycle so that all the other criteria will become ready and the only one that is not ready is the EGR. At this condition you can pass inspection. Preferably you want to do this using a cheap 30 dollar scanner so you can monitor it properly. Once all are ready except the egr do not turn your car off. Head to the inspection place and leave your car on. When it’s your turn to get inspection the inspector will hook up your car and you will pass inspection. Make sure the inspector does not turn your car off then drive it. On explaining how to test EGR monitoring I have to post a video because it’s a bit complex. I will also post a video on the hack. This is good because it will give people time to diagnose their car instead of paying 100 bucks for a hot inspection.

I totally agree other versions of prius are way more complicated.
It did not fix i, problem is not clogged egr.
My prius c has 233,000 mi. I'm thinking of cleaning the egr as it's having knocking at startup more often now

You will work much easier if you do but with patience Don't need it

Awesome comment are a you toyota technician??

Having same issue.
Share your experience if you have fixed the issue.

How do you remove the egr cooler? Those 2 nuts are hell to remove.
Yes they are but since I had a spare engine I could guess how to remove them

Whatever rich dude. I used to clean the egr on my Tercel yearly. I'll do the same on my prius. Egr valves are very expensive

I got it really cheap don't know why
$300

So how to take care of the code then??? My Prius C has this code P0401
