Drove it under 2800rpm for most of the year and a half, it maxxed out at 68 mph without a hill climb. Will welcome any and all suggestions and will keep posting to this thread with what I have done until they are running rightĪfter trying the spool valve, both screens, timing solenoid, way too much futzing over a year and a half.

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. Have never heard of anyone having luck taking it to a dealer. Heard suggestions of adding Marvel Mystery Oil to oil? 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. Has anyone out there had this problem and was able to fix it with anything other than what I have done? Changed oil twice afterwards to remove all traces of flush from systemĬhanged regular oil pressure sending unit Replaced entire VTEC spool valve assembly (including another pressure switch)Īdded 5-minute oil system flush to oil to totally clean system. Have went beyond this on the 03 CR-V - all of the above plus: The ones that it didn't fix seem to have tried everything and nothing worked - ended up selling or scrapping the vehicle. Replaced VTEC screen and gasket behind P/S pump on blockĬleaned and checked all electrical connectorsįrom all the internet posts and forums I have searched, these fixes seem to fix the majority of the problem. My 2003 CR-V (199K) has had the same issue for months - shows as P1259 (VTEC malfunction)Ĭleaned spool valve, replaced screen and gasketĬleaned screen on oil control valve at front of block

Turn ignition off and back on and goes out of limp mode but usually come back on soon. CEL comes on and goes into limp mode (won't go over 2800 RPM). Well my 2005 Element (212K miles) became infected with the P2646 VTEC malfunction code last week.
