P2646 Rocker Arm Actuator Prf or Stuck Off

Hi there this may be a faulty VTEC solenoid, I would have this checked first, also when was the engine last serviced and the filter changed?

Hi, From what I'm Reading, Remove the vtech Solenoid and clean, Also Replacing the oil Pressure switch. But do the cleaning first and Clear the code Then See if it Returns. You Can Find Info, about this, Just Google P2646 honda accord.

Hope This helps You,
Good Luck
