The VTEC solenoid is on the passenger's side of the head on the exuast side, it's a small cylinder that has a green electrical connector on it. Either the wiring is done poorly or it needs to be cleaned.

Since you have two other common wiring-related codes, I'd suggest that you go over your wiring harness thoroughly.

Yeah, just because it's got wires going to it doesn't mean it's wired properly. Do you have the Factory Service Manual with VTEC Supplement? If not, you can download both of them through a link in the FAQ. There are troubleshooting procedures in there.
