I had a pretty severe oil leak coming out of the vvt and replaced the vvt solenoid and now that this one is on my car is misfiring at 40mph with the two codes that popped up which were p2646 and p2647 the p2646 code is a rocker arm actuator code and the p2647 code is rocker arm/oil pressure switch said more but can’t quite remember at the moment has anyone experienced this and if so can you possibly tell me if this means the vvt solenoid we put on it may be bad? Or maybe the oil pressure switch on it is?
and both codes are on bank 1

 

If your Accord is the 4 cylinder, try replacing the rocker arm oil pressure switch (VTEC oil pressure switch).
