I'd agree with that.. the Napa vvt spool piece didnt not fix my problem.. I cleaned & reinstalled the original with a new gasket.

It's been exactly 7 days since the repair, still running good and no codes. Im thinking the small cracks in the rubber gasket caused the code but all the engine oil flushing I did wasn't going to hurt either. I have a complete new Napa rockerarm selenoid/ pressure switch spool for sale if as anyone is in need of one.
Still trying to figure my element out, same code, replaced parts, cleaned screens, still nothing. Changed oil and filter, removed vvt valve assemblies and cleaned , still trips code

Well my 2005 Element (212K miles) became infected with the P2646 VTEC malfunction code last week. CEL comes on and goes into limp mode (won't go over 2800 RPM). Turn ignition off and back on and goes out of limp mode but usually come back on soon. My 2003 CR-V (199K) has had the same issue for months - shows as P1259 (VTEC malfunction)

What I have done so far to the Element:
Replaced oil and filter 5W-20
Cleaned spool valve, replaced screen and gasket
New VTEC oil pressure switch
Cleaned screen on oil control valve at front of block
Replaced VTEC screen and gasket behind P/S pump on block
Cleaned and checked all electrical connectors

From all the internet posts and forums I have searched, these fixes seem to fix the majority of the problem. The ones that it didn't fix seem to have tried everything and nothing worked - ended up selling or scrapping the vehicle.
Have went beyond this on the 03 CR-V - all of the above plus:

Replaced entire VTEC spool valve assembly (including another pressure switch)
Added 5-minute oil system flush to oil to totally clean system. Changed oil twice afterwards to remove all traces of flush from system
Changed regular oil pressure sending unit

Has anyone out there had this problem and was able to fix it with anything other than what I have done?
Have never heard any mention of the long oil control valve in front of block being bad other than cleaning screens on it - may try this next but don't want to just keep throwing parts at it.
Heard suggestions of adding Marvel Mystery Oil to oil?
Reprogramming ECM?
Have never heard of anyone having luck taking it to a dealer. They insist on following the troubleshooting flowchart and will end up replacing all the parts again and be out a lot of money and still not working.
Will welcome any and all suggestions and will keep posting to this thread with what I have done until they are running right

If the oil is at the correct level I would start by pulling the vtec solenoid on the back left of the cylinder head and clearing the mesh screens in the gasket of debris and go for a drive to see if that fixes it. I have seen the pressure sensor go bad on the solenoid and cause these codes also. But start with the screen first. The good news is Sarkari Result Pnr Status 192.168.1.1 that's it's not usually expensive to fix

Never had figured out. The E has been parked for months as I have other projects needing attention. Seems the oil pressure must be right at the cutoff for activating the switch. Way too much work to change the oil pump - dropping the front subframe to remove the oil pan - for something that may not even work. Thinking of buying various brands of cheap pressure switches - just the switch, not the whole solenoid - off ebay, hoping some brand might have a slightly different oil pressure activation point and may work. Have an 05 element that works fine with WVE brand pressure switch - would trip code with Beck Arnley or original Honda switch. Tried all three on this one with no luck.
Was the problem ever resolved

Do you still have the problem on your vehicle, was it ever fixed

I checked the plug and it had some corrosion on it, i cleaned it with some brake cleaner and also with a cotton swab, let it dry for a while, then applied dielectric grease and silicone on top of the plug, i really hope this works this time...
Brake cleaner is not contact cleaner. It may wash off loose oxides but will not remove tarnish, a non-conductive coating, from contacts. Dielectric grease is a hydrophobic insulator, a nonconductor used to seal connector bodies and prevent arcing, not to lube the contacts.

My daughter has this problem (now at 219,000); it occurs only after about 45 minutes of highway driving (engine good and warm). I had a long discussion with the service rep at the dealer she was taking it to - after replacing solenoids, valves, screens, etc. they finally did the correct thing and actually measured the oil pressure at the pump while driving it for 45+ minutes - low oil pressure. If the pump isn't putting out enough pressure, no amount of changing spools and switches will solve the problem. It may not be the pump's problem, I suspect my daughter's is just a worn out engine (she wasn't good about having the oil changed and keeping it full) so the engine leaks oil from bearings and the VTEC system resulting in low oil pressure. She is currently running 5W30 oil, but still occasionally gets the code. She doesn't use it for long trips anymore. Mobil1 makes a turbodiesel 5W40 that might help more at elevated oil temperatures while not hurting cold starting too much. Worth a try before replacing or rebuilding the engine.

At about 205,000, her E was using almost a quart of oil every tank of gas. I pulled the head, dropped the pan (lifted the engine off the cradle), pulled the pistons, honed the cylinders, installed new piston seals, rod bearings, and valve seals. Now it doesn't use oil between changes. I should have figured out a way to replace the main bearings without removing the engine.
