Honda p2647 another one FIXED!!!

• P2647 honda variable c...
update... approximately 2 weeks later car would sporadically show VCM stuck off code. engine issues due to incorrect oil viscosity cannot be corrected by simply changing oil in this case, the engine clearances are too far gone. despite the engine working perfectly fine, engine oil pressure couldn't be maintained within engines reasoning preventing check engine light from resurfacing randomly. this truck just need another engine. or gear oil 😆

[@nehalmascarenhas543]

Started getting this last year at about 130k. Car has always had it's oil changes done at 4-5k miles by me. After it happened, I checked the solenoid which was fine with no junk on the screen. Ran an engine flush and the oil and screen were still clean. I'd only get the code after the car warmed up and I came to a stop. Long story short, In the end using 10w40 oil fixed it. My thoughts are that the 5w20 oil just isn't good enough for this car long term.

[@MylifeMB]

you didn't fix the issue unofrunetly, all you did was put a band aid on the oil pressure issue or sensor issue. I did the same thing for a couple thousand miles and it fixed the issue but ended up replacing the sensor, after testing it the sensor was definitely the issue. never know when it's going to leave you stranded, it just wasn't save to drive on 3 cylinders in limp mode.

having this exact issue on my 06 odyssey 204k mi, shows low pressure 4-6 psi, vcm suck on, random misfire codes, was honestly looking at the screen in the gasket for that pressure sensor and the Vtec solenoid before I saw this video. I bought the van recently from a "Honda guy" but not sure if he used the right viscosity oil or maybe the no name brand filter on there has given up the ghost. More investigation is neccessary I see.

ive been dealing with this issue for 10 months (even took to garage $180 to say its oil pump $600 dealer only part + HUNDREDS to lift engine or drop sub frame to replace) yet no oil light etc, changed VTEC solinoid, changed oil & filter, and "was good" for 2400 miles. discovered the VTEC had a crack around the gasket (oriellys warrentied) changed oil/filter AGAIN. still 2646 or 2647 came up. changed the electronics on VTEC ($14 amazon) ans so far FINGERS CROSSED. no issues. it had gotten so bad VSA was coming on in town under 35MPH. its been about 1000 miles??? no issues 04 CRV 4 cyc

[@ahmetletif1822]

I have a J-series engine (2012 Acura TL with 131,000 miles). I’ve changed the oil filter, oil, followed by flushing the oil out 1,500 miles later, changed the solenoid, the oil pressure switch and still have P2647. What can I do if the VCM or PCM is faulty? Looking at context clues, this CEL came on after my stock Acura battery failed and corroded. I’ve since changed the battery but yeah still problems. My engine runs fine, just runs rich because of the CEL

[@brianbacich9999]

Those sensors don’t typically go bad, however the o-rings on the sensors do. Usually the filter inside the vcm will get clogged. To get to it you have to remove the vcm from the engine, Crack her open and change the gasket/filter. Also try using compressed air to blow out any debris inside oil pressure switch. Then run clean oil and filter. I’ve heard claims that seafoam can help clean the carbon deposits inside the vcm system as well but haven’t tried it myself. Carbon build up can lead to the vcm valve sticking open or closed. Hope this helps buddy

[@MylifeMB]

put some sort of vcm muzler to see if it fixes the issue, check all ground connections especially the ones close to the battery if you had serious corrosion issue, perform idle relearn before driving. check conncention on the vtech solenoid with voltmeter, check the ohms, sometimes they are faulty right from factory.

[@MrSamPhoenix]

@@brianbacich9999The Acura TL never used VCM. Acura went against because it dulls the engine. So only the V6 equipped Hondas have it.

I’ve got an oil pressure gauge inserted in my engine oil pressure port and it reads about 30 at idle hot, but it goes to 100psi by 3000rpm, goes to about 120psi at 4000rpm. Is that normal?

[@partsshooter]

No, it's not normal... your gauge may be uncalibrated, oil pump was modified to increase oil pressure, or an extremely thick oil was added like gear oil 😆. Typically, max pressure is like 80. The rule of thumb with oil pressure is 10psi per every 1000 rpm. With a warm engine, 1000rpm should be 10psi, 2000 will be 20psi etc.

[@MylifeMB]

sounds like a bad gauge or you are running gear oil LOL why do you have an oil pressure gauge in the first place? sounds sus LOL

[@stophatecollaborate5419]

Those kind of a real particular on the oil on those vtecs at least on my Honda Odyssey takes 5W20 and do not use Lucas it will cause the same issue, Lucas is a very good product I love it but Hondas don't like it. I recommend if you're going to do an engine flush use (1 quart ATF not dexon mercon) let the vehicle idle for 30 minutes. I've been using this stuff all my life it does wonders.

[@jann7262]

I’m glad I found your video. I was fixing a leak at the vcm and also changed the oil with fram filter what the customer provided. Suddenly the code 2646 and 2647 popped up.

[@randyrojas9291]

Just did the oil change on my odyssey still smells like it’s burning the oil white smoke coming out tailpipe also changed pcv valve and changed the whole Vvt assembly idk what to do anymore

[@randyrojas9291]

Any recommendations?

[@partsshooter]

@randyrojas9291 assuming your p2647 is due to oil consumption and when adding oil it does away! Oil usage is trying to be resolved, your main symptom for the oil consumption causing code p2647 is the tail pipe smoking. Which is an indication of valve seal failure! What causes this on honda is valve seals get old from lack of maintenence, oil change interval or just natural wear and tear. When the valve seals leak in the port, it causes oil to accumulate in the port and when you pull off, IT SMOKE! The only fix is to replace valve seals. To isolate the cylinder, pull and inspect the spark plugs, the culprit will have more oil, look fouled and wet black depending on how severe the consumption is. Typically I see cylinder 3 look the worse or the rear bank numbers 1 2 3. Changing the plugs will increase burn efficiency but will not correct your issue! You can change the viscosity and go up in oil weight to slow the smoking down. Like from 5w30 to 10w40, but it'll still smoke. There additives you can add to the oil that will expand the seals over time and "stop" the smoke but these typically don't work! If you decide to try, change the oil with regular 5w30 and add the additive. Drive and cross your fingers! If you have will over 250k, I've had lots of success with 15w40 by rotella used for diesel engines, significantly reducing oil usage and slowing down smoking. But at the end of the day, it's an 80 percent chance you need valve seals!

[@randyrojas9291]

@@partsshooter so would these valve seals also cause any slight knocking due to how fast the oil is being consumed

[@partsshooter]

@randyrojas9291 knocking? Well depending on the pace of the knocking. I think of ticking with honda. Knock it pretty extravagant, but the answer is yes, but only due to loss of oil and thus causing irreparable damage! You may have valve adjustment issues! Without diagnosing, I can't say conclusively

[@randyrojas9291]

@@partsshooter got it knocking can only be heard when I accelerate and it very faint nothing crazy ok I’m definitely going to take a look at the valve seals and the cylinders to see which one is leaking

[@bwoodyy]

It might be the TBTen or valve adjustment on tapping. Low oil pressure sensor, (not switch) might be bad and giving a wrong reading. When they go bad, they make the oil light blink or stay on as it warms up.

I have an 06 Honda Odyssey with 272000 That I bought from a Christian with a scanner in his hand 🤔 After driving it for about 10 minutes VSA/ engine light popped on and the engine was shake no power shitty gas mileage. He said he had just change the oil in it after watching a couple videos on KZbin change the oil w 30 the VSA light would pop on and off mostly on the expressway but not as bad so I knew had something to do with the oil or filter. The oil change place recommended that I use a little thicker oil 5W30 because it has 272,000 Miles so my next oil change I use the right oil 5W20 and I used a wixon oil filter. VSA light fixed the only time it pops up is when the oil gets real dirty. Giving you guys some advice don't buy a vehicle from a Christian Arab or someone that has a scanner in his hand 🤷 🤣😆😂🙏🙏🤗 I

[@vhg8638]

i used to go to late night congregations of hundreds of people with my dad when i was younger. One of those times we rode with a "cristian" car salesman. He mentioned to my dad why the speedometer wasnt working--- he would unplug the speedometer related sensor as to not log more miles on the engine. He would drive many cars like this and not add more mileage to vehicles, thus keeping their price intact. I remember even hearing that somehow they would "revert" the miles on the display. Most of them were not digital at the time, mostly mechanical, like the counters used in events sometimes where you click once for every attendant and the numbers would just rollup. I didnt say a thing but was aphalled that he so confidently and proudly admitted it.

Do you need to get a subscription for this ms906bt scanner ? Will it work without the subscription in full capacity? Thank you in advanced.

[@partsshooter]

When you buy the tool you get a 1yr subscription update. Once you purchase and do the 1st start up, you need to connect to the internet to register tool. The tool will be link to you only. After the registry, you don't have to use the internet unless you get on it via scan tool. The tool doesn't stop working after a year. I haven't updated my new one in 2yrs. Updates cost depend on tool. Usually around $650 to $1000 if you decide to. But that money can honestly go towards new scan tools We're typically 5yrs behind anyway... if you're at place where you deal with newer cars then keep your Updates regular annually. Just look at tool comparison before you buy. They all aren't equal tools

[@partsshooter]

You may have to change the viscosity, depending on the millage, the oil pressure may not be sustainable during cylinder deactivation mode because of worn components. Try a 10w/30 if your over 150k engine miles and see if that helps. If you haven't change the complete assembly, you should do so. I know they're expensive but if you're not thoroughly diagnosing it, just replace the entire assembly. Typically it's one of the components. Oil pressure switch or solenoid. Rockauto.com will have it at a responsible price vs part store. Also to assist further, I'll need oil pressure numbers at normal running conditions and data during deactivation...

@@danscreativespace I hate to say but you're gonna need factory compatible data like I have in the video. You need to review the values presented to PCM from necessary sensors. You can bench test the oil pressure switch with an ohm meter and air pressure though. The oil pressure sensor is a varying potential resistor that isn't just in or off like oil pressure switch at oil filter housing. If I recall, the oil switch is used as reference once ACM is active, if I recall!

1.Replace oil filter housing gasket (common leak ) 2. Oil and filter change 3.Replace Oil pressure switch gaskets and O rings Very common on odysseys with high mileage Also the rattling noise could be timing tensioner gettin stuck wich is also very common on these odysseys due to the oil leaks .
