The solenoid isn't the problem, it's your pressure switch. The switch basically tells the engine when there is enough oil pressure for the VTEC system to operate. Try replacing the switch.

Re: VTEC pressure valve (MOST)
If the sensor is working properly, it goes off because there isn't enough oil pressure to activate the VTEC solenoid. That means there could be a problem with your oil system not building pressure. Refer to your repair manual for the procedure to test oil pressure. You may need to bring it to a shop.

hmm, i have used two vtec solenoids and still throwing the same code, but i guess i'll take look for the oil pressure procedure.
