There are a few things that can cause this. If the VSS (vehicle speed sensor) on the transmission is not working you will not be able to use VTEC - you should also get a CEL for that. If the engine temp probe fails you will also not get VTEC as it requires 155 degrees to allow it to operate.
The more info you can post the better people can help :-)
Could be speedo, could be your coolant temp sensor isnt reaching operating temp, and also try cleaning your vtec solenoid... I've had an issue as simple as that, and cleaning it out fixed the issue!
It's called the "Spool Valve" on Majestic Honda. Most people just call it the "VTEC solenoid".
