Hey guys!
I am getting a check engine light error "p2647" which is stating "A Arm Rocker Actuator System Stuck on Bank 1"

I have tried to replace the Oil Pressure Switch that is located above the oil filter (I have a D17 engine that is not equipped with a VTEC Solenoid)

I am experiencing symptoms like others are for a bad VTEC Solenoid. Car can cruise up to 40 MPH but if I try to press on the gas I lose all power in the engine and the car basically goes limp.

I have also recently changed the oil with 5w-20. Oil is topped off and clean.

And ideas on what else I can do? I am thinking about ordering an OEM oil pressure switch versus the one I got from Autozone to see if that makes any difference.
