It's not always the VTEC Solenoid assembly. Sometimes it's the connector TO the assembly. The rubber grommet on the connection can get aged and susceptible to moisture, creating the very same scenario - especially and almost exclusively in wet weather.

[@KRiSXC0RE]

I think that is exactly my problem. My element will throw p2646 every time I drive it in the rain . I’ve changed the whole vtec solenoid assembly 3 times already and it still happens every time it rains. Is there a way to order a new connector?

Changing the oil regularly and checking the oil level often are the best ways to keep the VTEC working properly. Great video Jim.

I think you are the most amazing teacher, mechanic, human, man.. I love you and your videos. You have inspired me and taught me so much. I am a 50 year old African American female, and I have a Honda Element, and I am experiencing this problem. I actually learned so much from you. I wish I can meet you and I wish I can get more videos that are explained as thorough as yours thank you so much

[@joebeezy9471]

Writing this in the hope that it helps someone that is dealing with this issue. 2007 Accord 2.4L. Oil changes were not done on a regular basis. Code P2646 showing only. Car experienced the ‘bucking/stuttering’ past 2500 or 3000rpms, fine below that. The first thing I did was check the oil. It was low so I added a quart. The issue did not resolve. Went and got the VTEC solenoid assembly. I changed that out and the car ran fine for about 15 minutes but then the code came back on and the issue started again. Removed the assembly and saw the screen was full of gunk. Cleaned the screen off and took the car back out. Ran fine for 15 minutes and then the code kicked on. I then changed the oil and filter and also removed the assembly again and it was full of gunk. Cleaned it off again. The car ran fine for about 15 minutes again the code came on and the car experienced the same issues. Took the assembly off again and the screen was full of gunk. Cleaned it off and put it back on clean. After this last time the car has been running fine. No code. No issues. If you know oil changes were not done on a regular basis then it’s safe to assume the engine is full of crap that will clog the assembly. The first thing you should do is flush out the engine to remove all the contaminants. Change the oil, and filter and clean the screen. If the issue happens and the screen is clean when you remove it then the assembly could be bad. If the assembly is new and the screen is clean when you remove it then it could be the harness. If the harness is new, the assembly is new, and the screen is clean then it could be the oil pressure switch or the oil pressure sensor. Hope this helps!

[@lotusthe3rd831]

did you experience misfire?

[@Noname-lk2ol]

Wow. You are EXTREMELY good at explaining things in ways other mechanics think are irrelevant. Its the extra little things like explaining that more oil and cleaning the screen can "possibly " fix the issue as with other mechanics they'd just get straight to it. You're helping a lot of people man. Appreciate your thoroughness, Dont lose that character trait its a damn good one.

[@CallanChristensen]

I had this same code. Ended up being that the plug connectors between the harness and the oil pressure switch were corroded. I sprayed CRC 5103 Quick Dry Electronic Cleaner on both the connector (female) and oil pressure switch (male) connectors and then gently but firmly inserted/removed the connection to scrape off the corrosion. I did this 3-4 times, then wiped any residue, sprayed and went again. It didn't take that much time. I tried using a few tools to clean the male/female connections but inserting/removing the connectors ended up being the easiest. At some point in the past, the harness connector's locking tab was broken off, so I think this was allowing water/moisture to get into the connection.

[@cliffords.8341]

Jim, this video is better than any other video's I watched so far. You go as far as explaining in more detail and even mention cleaning the engine where the gasket surface is to remove old oil and any dirt and debris when no one else did. I'm a retired motorcycle technician and machinist and cleaning gasket surfaces is very important. I just bought a 2005 Toyota Element EX with the 2.4ltr engine with an automatic transmission. Last night I drove it home 4 miles then fifteen to work today. Leaving work 500 feet down the street the engine started bucking on acceleration about 30 - 35mph and the engine light came on. Found out the codes are P2646 and P2627. Going to take it back tomorrow for them to replace these parts. It came with no warranty, but I'm sure they'll take care of it. Being a retired motorcycle technician and machinist, they're going to get a tip because it's the right thing to do. It's not their fault the part(s) failed. Also a message came up on the instrument cluster that says "Side airbag off", then turns off and comes on. It did this all the way home.

[@PartikleDestroyer]

Thanks so much Jim. I had the P2647 error code, the 3 lights and bucking on my 2005 CRV. I had it into the Honda dealer twice and they wanted to replace a ton of parts to try and find the problem. I ordered the replacement part you recommended and it solved the problem.

[@elizabethf8078]

That's because dealerships are selling you up on stuff you don't need. I got the whole song & dance that it would cost $2000 to fix and was I sure I didn't want to trade it in.... I do all my own work now.

[@RedHorseAdventures]

I owe you a sincere THANK YOU. Your simple mention to check the oil level solved the problem and likely saved my engine. I just had the oil change 2 weeks ago at Walmart and they obviously screwed up and didn’t add the oil! Everything was dry underneath and they added the oil necessary(check engine light immediately disappeared). They also have the obd printout and if any issues turn up going forward they said they will cover the cost. As another note, the cruise control would not engage and that was my first indication something was wrong and the rumble shortly thereafter… Thanks again for this video!

The three 10MM bolts are a bear to loosen and they strip easy. I used a grinder to remove the lip off a deep 10 MM socket so all of the bolt head is gripped. Helps alot.

IMPORTANT! Don't buy Aftermarket VTEC Solenoid they are made in China with inferior parts. The Aftermarket Solenoid weights 400grams and the Honda original part Made in Japan weights 520grams.

Actually the smaller 2nd screen you are referring to doesnt get as dirty as the screen on the selenoid itself. At least that's how it was on my element, when it's time to change your alternator that is a perfect time to replace the secondary screen.

[@kevinkyzer2758]

9 out of ten I fixed at dealership only needed vtec screens replaced, caused they were clogged, due to oil not being changed on time, so recap replace vtec screens then change oil and filter first, 9 times out of 10 that fixed rocker arm code p2646 that caused the bucking. Also, vtec, will not engage with low oil pressure, or if your speedometer isn't working. Good luck... always check easiest cheapest stuff first unless you got money to waste, and the original honda solenoids are built well unlike the aftermarket stuff.

I hope it wasn't threadlocker. I was able to best come in from the bottom of the car. Also not sure on this CRV is the oil pressure switch is located below the solenoid but need to be careful. I initially came at it the way you did and the wire came loose off of the pressure switch below the solenoid. Had to fix that after the repair.

Thanks for the instructions, Jim. I have a 2003 Honda Accord LX, K24A4... Car seems to move fine but has a slight noticeable lag before VTEC kicks in. There is no check engine light, but there is significant oil leak that increases as the RPM increases. The oil seems to be seeping out from underneath the oil pressure switch and solenoid. Typically, oil soils the oil filter and the steering rack all the way beneath the assembly. I usually have to add up to one quart of oil per week in order to keep oil level within recommended limits. I recently changed the gasket between the assembly and the engine block. There is presently no leak at that point. Should I replace the oil pressure sensor and the solenoid? OR I should replace the entire assembly?

[@MrJOHNY347]

Does your car jerk when you’re accelerating heavily ?

[@braveheartii1534]

@@MrJOHNY347 Yes. It did at some point and triggered a VTEC solenoid code (P0406 or something). I replaced the oil pressure sensor on the VTEC solenoid and that sorted things out. I also did a valve clearance job which sorted out occasional misfires on cylinder 3 which I observed and refused to go when I changed spark plugs to new OEM and checked my ignition coils to confirm they weren't burnt. Note that I had to do the valve lash adjustment 3 times before I got it perfect. First attempt was too loose, hence noise like a sewing machine. Second too tight but moved fairly without noise. Funny development lately: My catalytic converter got significantly blocked. I guess that must have resulted from the periods I was driving the car around with the misfire, due to unburnt fuel getting to the cat. As a temporary measure, punctured a hole through the cat and car is back moving like new, with significant gain in power and fuel economy but obviously letting out some smoke instead of the usual steam. Looking for a replacement cat now. Damn expensive shit!! Should fix it ASAP. Cheers mate!

I was pretty happy after test driving it. When my daughter drove it, the 2647 was gone, the 2646 came back, and the car wouldn't go over 50mph like she said it wouldn't before. So frustrating. Suggestions?

[@cocoputhyxo]

Mine can’t get over 80mph and I’m glad I’m not the only one going through ts issue. Probably should get the piece fixed… if it’s still doing it

[@metalmanipulator7210]

@@cocoputhyxo No, it’s fixed now. It ended up being the same valve. For whatever reason, it like Honda equipment over what you can buy at O’Reily’s. I suggest using dealer supplied parts. It reminds me of my Apple phone that only uses Apple cables, etc. or it gives me an error. Why the Honda valve worked, no idea.

[@cocoputhyxo]

@@metalmanipulator7210 I was going to buy it off car parts online but how much did it cost to get put in???

[@metalmanipulator7210]

@@cocoputhyxo Here it’s a couple hundred (Sacramento). I blew that on the aftermarket one also. In reality, it looks like it should be $50, at the most.

nice work jim think I will come across this soon my way the exhaust valve clearance closes on these too so the need adjustment

[@S4h4r4s]

Thank you for the video. This exactly describes what's going on with my 2007 Honda Element. I'm ordering a new Valve Spool Assembly replacement. Hopefully, it runs effeciently after the check list

[@aaronyarbrough2867]

Did you end up repairing it like on the video? Did it work and has it been working? I got the same code and have a 08 Element.

@@aaronyarbrough2867 Hello, yes I have installed a new one purchased through Rock Auto. The engine light is now gone and my RPM is not misfiring anymore after the installation 🙂

[@davidcutsinger3574]

Was that a Honda one or a off brand solenoid?

I have been getting the 2646 error code and went thru two VTEC solenoids made by Dorman. It works fine for a few miles then all of a sudden I get the bucking bronco at 2800 rpms. Any suggestions?

[@redhaylo909]

Get an OEM part, not aftermarket like Dorman

[@501mister]

Worked like a charm. Thanks

[@1fast_gen4]

Great video but the ACTUAL fix to the p02646 and p2647 is to flush the engine multiple times because these 2.4 motors get the oil passages clogged up and that is what causes oil to push through the oil pressure switch causing the codes. Replacing the solenoid will only temporarily fix the problem but light WILL come back on. Flush the motor atleast twice and problem is fixed

[@ahmetletif1822]

What about a J series 3.5? I went and took the assembly off and cleaned the gasket on the assembly and replaced the solenoid too to no avail. Last thing I wanna do is get a whole assembly when I just replaced the solenoid and there wasn’t anything wrong with it. Thanks!

[@c172215s]

SO I did all of that Works great until the engine gets good and warm. (About 15-20min of driving) the Vtec shuts down and 2646 pops up. Engine has high mileage (298K mi) well taken care of. very clean inside. Good compression. Doesn't burn any oil to speak of. any suggestions? My guess is that the oil pump may be worn enough that when the oil thins out ant operating temp there is just not quite enough pressure to trip the switch. The one thing I have not replaced is the Vtec oil valve below the cams. I did clean that as well as the front screen when I did the head gasket a while back.

[@SingleSpeedMoron]

Great videos by the way. So, I had the P247 Code and replaced the entire unit. a few days later I'm getting the same exact issue. Would a bad connection (tiring harness looks a bit frayed) would the oil pressure switch right above the oil filter cause this?

Your video was very helpful for my 04 CRV. One tip that worked for me was to remove the 3 bolts first as that gave me more wiggle room to disconnect the electrical connections. Also, is it necessary to disconnect the battery first? Thanks

Should not need to disconnect your battery to work on your vetch solenoid.

I have had this problem with my Element for 3 years, I have changed that valve 2 times sensor 2 times, I didn't know you would get that code with low oil. Thanks for that. But now I'm wondering will you get that code when you have a bad oil leak, even if you fill the oil up to to the right level???? With that in mind should all oil leaks be fixed first. I have spent so much money and still have the same problem. 😢

[@johnojohn1000]

Thank you for the solution to my problem.

[@asheradventures5899]

So, we have this problem on our 2005 crv. We’ve done all these steps, replaced the assembly, oil changes, check levels. But it is still throwing this code when the car gets hot. We have exhausted our knowledge which was limited based off of what we could find out youtube. What should our next step be if after doing all this, the car continues to throw the code and shudder around 3,000 rpms after the car has warmed up. Also this car was a recent purchase and at the time didn’t have any lights on. Thanks in advance

[@edgardoarroyo7418]

Jim, I just bought an Element about a month ago. Im having some random bucking or kind of. I just removed the spool valve look to be an original one and look relative new. The gasket was perfect with no leaks and the filter was 100% clean. Maybe is the Transmission selenoids?

Same code but my car doesn’t stay idling it just dies out after about 15 seconds of struggling to idle but when gas is added it revs up just fine but below a certain rpm it won’t idle and die
