My newest code is a p2646 which is rocker arm actuator control system performance stuck off bank 1.Vehicles with the VCM-2 system shutdown cylinders 1-4 in certain scenarios on 2008+ model and some may be eligible for the engine misfire settlement from honda. The 2005-2007 Honda 3.5L V6 is a VCM-1 engine and only does cylinder deactivation on cylinders 1-3 instead of 1-4 like the VCM-2 engine.Yesterday "check emission system" sign and check engine symbol came on. They are still on today. The engine runs normal, but ECO sign doesn't come on at all. I guess all 6 cylinders are activated all the time. I took it to autozone to read the code. It showed "P3400 VALVE PAUSE SYSTEM (VPS) STUCK OFF BANK 1". It's 4 years old with 56,000 mls.Code P2646 indicated the PCM detected that the variable cylinder management system was stuck in the Off position. ... system performance or stuck off bank 1 ...may be on with DTC P3400 and/or P3497 (VPS Stuck Off Bank 1/Bank 2). PROBABLE CAUSE The VCM (variable cylinder management) function may repeatedly switch on and off during certain light throttle operation, at cruising speeds, on flat roads. This frequent switching can contribute to increased oil consumption. The updated PCM software improves.
