Still P2646
Alright I took advice took my car back to Honda dealership and they ran the code reader and p2646 then they replaced my wires, sensors new oil pressure switch and cleaned the screen and solenoid screen but before this problem I had the head gaskets replace because of a overheating problem Honda told when they grinded the head and resurfaced the valves but also they checked the olms on the sensors and they checked my ecu and everything was fine. Externally everything was fine so I'm out of thought.
