For anyone still looking for a possible fix to this, I'm glad Aiman mentioned it, but I just learned this before watching: the cause of my P2646 was due to my VTEC OIL PRESSURE SWITCH (4:14) and what literally happened is that the connector had possibly vibrated off (I knew it had to be simple cause I had bought brand new ones half a year ago, and before that with my older engine [I blew a gasket on that one] I was buying a new solenoid and/or gasket every 3 months). Thanks for mentioning it in the video, and hope my find helps someone out there. Sucks I gotta sell this 05 Accord, helps me learn a lot about the little things thats important, in addition to maintenance

This is a great video! I really appreciate the time y'all took to explain out your thought process. That is the most helpful thing for people doing mechanical work at home who don't know a lot about engines, like me! Thanks again!
Hello, good Lord the last time I saw you I was looking for some information, about how to grow up turmeric. Was so easy for you, but no for me didn't happen. Why to pay if can fix it, you are so intelligent, and likeable. And of course such a good brother😊
Correct me if I'm wrong, but based on Aiman's research and my experience, if you get error P2646 and you keep up with your maintenance, it could be your solenoid that’s the problem(solenoid and/or gasket or connectors). If you don't keep up with maintenance, it could be your engine that's the problem (fluid levels mainly)
Thank you for the video and I appreciate it yes generally a Low oil's issue with this Honda's civic and yeah you gotta leak somewhere.. Cause you should not be 2 or 3 courts low. So you're right on the money with that rocker arm code bill but it's generally just an issue of you aint got Enough oil in your car. RLTW 3/75
Paid $400 for parts labor on oil pressure solenoid due to car losing power/ car bucks when accelerating. Now I'm getting this rocker arm oil pressure switch code. Car is still bucking. Apparently oil pan gasket is leaking oil as well. At this point i can't dump more money info this car. Looking for an additive to help w oil pressure.
the bucking was probably due to a bad oil pressure switch, the part is is about 30 dollars on amazon, mine had the same issue after i replaced the solenoid. the parts arent too complicated to change as long as you have the right tools. that 400 dollar bill you paid for the vtec solenoid is about $50 or $70 for a quality one, and an hour of your time to change it out, check out rockauto for car parts. They're great cars but they nickle and dime you. you fix one problem and another soon arises. hope you fixed your issue!
@@showcase2396 thank you! For now the cold weather seems to have solved my problems. Thankfully I'm not commuting 5 hrs a day so it's not a pressing problem and i do have the luxury of trying to fix it myself once spring comes around. 👍
My CRV has the SAME ISSUE - jerks/hesitates - your videos has been very helpful to mebecause I got the PART NUMBERS - I bought this car USED without MECH RECORDS ?
Thank you for making this!!! I've been battling the EVIL P2646 for over a year! I've cleaned both screens, it came back. I've replaced the assembly with genuine Honda part, it came back. I've replaced the VVT solenoid on the left side of the engine, it came back. I'm always up to date with my oil changes and I'm not losing oil. At this point, I'm at a loss, help 😭😭😭😭
David Garcia sams here. I found. This online tonight. --- It was an oil pressure issue I only had 10 psi at idle and I believe around thirty at 2300 rpm but 60 at3500 rpm. It didn't always have enough pressure to operate v tec I tried Lucas additive also and no help. We figured out something we installed a relay and jumped wires from switch to solenoid and a ground. When PCM operates the v tec solenoid it will open the relay and think the v tec is working normal. Seems fine now have driven about 40 miles. It was figure this out or replace engine which runs great like it always has.
So, it’s been 3 months since you replied with your fix. How is your workaround working out now? I’m facing the exact same issue. Replaced both screens with genuine Honda replacements. Replaced the entire assembly, which worked for a month. Increased the oil weight to a 10W30 High Mileage oil. The only thing I haven’t tried is the Sea Foam additive, but that’s next. I don’t expect a miracle from the Sea Foam though.
Try checking the connectors (switches) on the solenoid. This error just happened to me and I think over time the oil pressure switch got vibrated off cuz when I lightly pulled on the switch, it just popped right off. Pushed it back in and tugged again and didn't budge. My accord now has 1 less problem to worry about
Hello I replaced the VTEC Solenoid and gasket on Sunday and drove it around and drove to work fine. Then on Wednesday the engine began surging at about 2800 rpm . Havent checked codes yet. Could the new one be bad ? Thanks
I have a 2006 Honda odyssey it gives me the code P2649 Rocker arm oil control solenoid VTEC solenoid valve circuit high voltage. Do I just change the port or worry about high-voltage? I also have other codes P2770, P0970, P0980, P0966, P0974. There all giving me high input, high circuit or low circuits. Should I just change the parts or is this a different issue? The car wouldn’t start I thought it was a battery and alternator issue. I replaced both of them. The car ran for a few miles and it shut off on me I couldn’t start it without a jump. Also I need to mention before it shut off on me every time I stopped and try to accelerate it hardly did.
Iv replaced the valve twice and done two oil changes in 100 miles and after the motor warms up it still goes into limp mode with this code. Any ideas? Mines a 2005 with 213K miles. Just bought it and drove it a few hundred miles before the issue surfaced.
Hey wats up, I have a 2004 Honda Accord ex v6 , my car been acting weird experience a transmission slip not to long ago and I know my transmission is not bad, did a lot of research and seen something about changing the transmission solenoid so I change both and also did a transmission flush with Lucas transmission slip fix and it was driving ok, now it’s shuddering and over revving like my transmission is slipping y think this may be the problem???????
My Honda CRV 2007 has the same code ,started 2 days ago ,and the car jilted couple of times the oil was very low I added oil still doing it .what you huys think needs to be done.
I had this code on my 05 si and its annoying car felt slow and wouldnt rev past 4k i took off the whole sensor and the gasket and cleaned everything with gasoline i didnt take apart the 2 sensors just clean everything good with gasoline and a brush dont be scared if its broken you will find out when you put it back on the car Btw my car had 225k miles ok
For some reason I unplugged rock arm oil pressure sensor,,,and I star the car the engine light is on ,,,,,than I turn off the engine plug the sensor back.... the engine light is off but everytime when I use scan tool to scan it the code p2646 always there.....if you know why please teach me ,what should I do next step .....I should drive more or replace the sensor or something other........thank you

Literally the same thing happened to me! This past week. So what did you figure out, or do to fix the issue?
It could be that, the vtc strainer, or the vtc actuator. Especially if you buy a non OEM vtec solenoid lol
I have a 2006 Honda odyssey it gives me the code P2649 Rocker arm oil control solenoid VTEC solenoid valve circuit high voltage. Do I just change the port or worry about high-voltage?

Thank you for this!!!
My Honda CRV 2007 has the same code ,started 2 days ago ,and the car jilted couple of times the oil was very low I added oil still doing it .what you huys think needs to be done.

Btw my car had 225k miles ok
and this solved your problem? mines doing the same thing so i tried changing the vvt oil switch and it didn't help
Thanks for the info. Too bad these codes are too broad!
do you have to drain the oil to change these screens? Thank you.
No, don't need to drain.

Same to me I think it just keeps it in the system to remind you and it will go away if after you had no code for 600 miles I think

Hi!
thats the worst you can do buying those parts from ebay amazon or autozne they are junk for me is totally worth it going to the dealer spend 30 mts and get my 10 dollar gasket and spend another hour installing the gasket on my car because is so difficult
got a part from autozone installed and 2 months later leaking again
dealer for quick fix or rock auto if youare not in a hurry
