2003 Honda Accord Vtec 4 cylinder codes 2646 and 2647
These codes are for circuit voltage on the oil sending unit, I replaced the sending unit and STILL have the same codes coming back and causing the computer to fall into the fault mode (won't rev over 2500 rpm in gear). The check engine illuminates and any time, not specific to engine rpm. Does anyone have a clue what ALSO may be wrong? I even changed the oil sending unit again just in case I received a bad one from Honda. PLEASE HELP!!!

You replaced pressure switch P/N 37250-PNE-G01?
V-Tec oil pressure switch, as in the March 05 Service News flyer?

Yes, in fact I read the bulletin before I repaired the car. I'll double check the part number to be sure. Thanks for the response. 
I double checked the part number and it is the one listed in the service bulletin. Could it be something in the Vtec solenoid valve?
