@richardd8352 6 месяцев назад

Id change out the oil when doing this, I did mine today - roll back 3 days prior- i got check engine and code. Removed solenoid - cleaned gasket filter and solenoid with brake cleaner. So i thought today id change the oil and put in a new solenoid gasket. Well after only 3 days the gasket i cleaned was full of crap. So prior to fresh oil, i used engine flush. If your getting a blocked filter on your vtec solenoid its a clear sign to change filter and oil. Absolutely NO point changing gasket without changing oil also. So today i had fresh oil in a flushed engine with a new gasket. Definitely good practice to do this. Also going forward im going to change out oil every 8 thousand miles.

Thanks for the comments! I've put about 5,000 miles on this CRV since changing the O-ring/screen. I've had no error codes, and no leaks.

@peterkleiner9114 Год назад

Pro tip: leave that first small bolt on - it only holds the heat shield to the solenoid chassis. Just remove the three lower bolts and then you can easily remove it after you disconnect the wires and remove the whole thing. Really, I think you could just leave the heat shield on for this, though I didn't. Thanks for the video!

@richardd8352 6 месяцев назад

Yeah I left heat shield on

@jimtownsend7899 Год назад

I just changed that filter assembly two days ago. Don't bother taking the heat shield off. Just undo the three bolts. I didn't even disconnect the plugs. I swung the spool valve onto the exhaust manifold, cleaned up both mounting surfaces with brake cleaner and a towel, then replaced the filter assembly (gasket with screen) and put it back on. Do not use any sealer of RTB, and do not overtighten! The bolts are supposed to be torqued to 8 ft.lbs., which is basically hand tight and about a half turn. If you tighten it too much, that's what flattens the gasket, and it will leak.

Fixed my problem. My gasket was all brittle and bulging into the passageway for the oil. Also seen cracked rubber parts on the screen. Replaced it, cleared the codes, and so far after driving around for a day it seems to be fixed.

@paward4 2 года назад

Excellent! Glad it helped!!

@Clintaso 2 года назад

I think what you did with replacing it is definitely the best option. If you’re going to take the time to take it out you might as well change it as opposed to just cleaning the screen. As far as diagnosing, there’s a step I’d take before even taking it out. When I got this code I figured it was the dirty screen as that seems to be the most common issue, but as with a lot of error codes, it could’ve been something else. To confirm it myself I just added some sea foam to my oil in an attempt to liquify any deposits on the (presumably) dirty screen and after idling for a couple minutes I was able to drive and get my RPMs up to normal highway conditions without issue...after only 30 miles the code cleared. Now when I go to change the gasket, I’ll have some peace of mind knowing that’s the true issue.

i just changed my vtec solenoid and now i have a p2646 code. I'm gonna check it out and see if theres anything obvious but do you have any suggestions? i suspected my oil pressure switch below the solenoid but from what i can see that would throw a p2647 code...

@octaviobourdon7287 Год назад

My brother only 8 foot pounds if you do 10 foot-pounds it is too much pressure on the gasket and it will start leaking after about 10000 to 20000 miles to get longevity after gasket it is recommended to only do eight foot pounds and try to have a torque wrench and it is best for you not to remove the heat shield lots of times the bolt 🔩 on the heat shield snaps, just trying to give you a heads up my brother. Very nice video I like it thank you very much

@brandonmyerhoffable 10 месяцев назад

If you're changing your oil you have a wide open shot at the 3 bolts from under the car.

@angelisone 4 года назад

ATG recommends to replace the whole assy rather than the gasket screen. Not fun climbing on the engine. Nice camera angles.

@paward4 4 года назад

angelisone thank you for the comment. Replacing the whole assembly is a good idea. For a car this old it may not be worth replacing the part for $60 unless I’m keeping the car for another 13+ years. I may not keep it this long so I opted to only change the screen. Climbing on a hot engine is not pleasant for sure.

If you've got a reader to get the code, it will likely also be able to clear that code. No need to unhook the battery and lock your radio.

@Dio0o0o 3 года назад

do you recommend using replacement gaskets or OEM gaskets?

@paward4 3 года назад

From my experience, with this gasket, there hasn’t been a quantifiable difference between dealer and aftermarket gaskets. If you’re doing anything on the throttle body gasket, I recommend getting it from the dealer. I had negative experience with my 2007 CRV throttle body non dealer gasket.

Hi... is this part is as same as Honda Odyssey 2008 . ?? I need price for whole assembly too. Thanks

The 2008 Honda Odyssey probably has a V6 engine. Therefore this would not be exactly the same. Although, it probably does have the valve but I have not worked on one so I do not know where that valve would be.

Thanks for sharing this amazing video....I wish I saw it earlier ...have an 06 crv and had the check solenoid replaced ...as the code coming up was rocker actuator...my check engine light triangle and vsa light all came on....after replacing ...the lights come back on from time to time....not sure if I want to go back to this mechanic again ....any thoughts? Oil was also changed when solenoid was changed

@paward4 3 года назад

Hi, thanks for your question. In software when you find a defect, you always test it again to make sure it’s still a problem. What would I do in this case? I would check the mechanic’s work... the O-ring between the valve and the engine. It’s possible there was some dirt or something left in place. If the mechanic shop looks to be clean and pristine like a Porsche dealership repair shop, then maybe that’s not the problem. However if it’s a questionable cleanliness/disorganized shop, it’s possible the O-ring is leaking. And as long as you have the valve assembly off, I’d probably get some (ATF+diesel fuel mixed 50/50) and give the valve body a good cleaning.

@shoaibb8862 3 года назад

@@paward4 thx for replying ! I only saw this now as I didn’t get a notification! Funny enough I went back to the mechanic today to have him look at it ...p2647 came up which was vtec oil pressure switch ...he advised that they cleaned the screen inside the solenoid because there was some oil crud ... he is saying that at next oil change I should do an engine flush ...I have 287k on the car ...any thoughts?

Would this b a similar process on a 2.4L vtec 2007 honda accord giving me the same code

It should be. Make sure you check the electrical connectors going to the vtec switch, and solenoid. If Ok, put a blog of die electric paste on both, and call it a day.

I will try this on my 08 honda element. I don't have any leaks yet. I'm going to change the oil and change the rubber thing tomorrow and hope the check engine light doesn't come on. Although the light comes on then it turns off then it would turn on again later.

I have an 05 Honda odyssey with the same code I change the VTEC solenoid and I still have the same code wonder what your thoughts are on that

@paward4 4 года назад

Seems that the Odyssey has the V6 so the specifics might be different. Here's some things I'd look at in the overall picture going from easiest to hardest. 1) History/frequency of oil changes. Is there any sludgy buildup in the engine (looking down the oil fill hole? 2) If you reset the code, and change the oil, does it still come on? 3) Is the VTEC solenoid receiving the proper power. 4)If you replace the solenoid, does the check engine light come on again. 5) A Google search on 2005 Honda Odyssey P2646 will turn up a plethora of info.

My code coming up is a p2647 which is saying my vvt solenoid is stuck on. You can try to just change the screen and filter and CHANGE OIL and oil filter when you do. If that doesn’t fix the problem it’s most likely the whole unit which has the solenoid and oil pressure switch. But that is around 200$
