2006 Honda 2.4L Code P2647
 

I been having this p2647 code for ever I've done everything I can to fix this issue, you name it I've done it.( All solenoids replaced, Rewired, Engine Flush,) The question i have now is, could my ECU be my issue and if so how can i reset it to factory, and don't tell me to disconnect the battery I've done that too and I've also disconnected it for a full 24 hours. Please can someone help me out with this, I don't want to have to bring this to the dealer mechanic shop.

According to this, the problem is usually the VTEC oil pressure switch
