What's the code p2647 Honda Odyssey 2006?

The P2647 error code in the 2006 Honda Odyssey refers to a malfunction from the rocker arm oil pressure switch and specifically is triggered when a higher than standard voltage is detected from the switch. This can be caused by faulty connections and wiring harnesses or the failure of the Variable Valve Timing and Lift Electronic Control (VTEC) / Rocker Arm Oil Pressure Switch.

The notice affects the 2003-2012 Accord L4; the 2002-2005 Civic Si; the 2002-2009 CR-V; the 2011 CR-Z; the 2003-2011 Element and the 2007-2011 Honda Fit.
