Rocker arm oil pressure VTEC sensor. My wife's pilot had the same error code and it turned out to be a loose connection of the Vtec solenoid on the rear Bank of cylinders. In her case, the engine went into limp mode which prevented us from going over about 15 miles an hour. I would definitely have it looked at and fixed before you drove much.
