The VTEC oil pressure switch is a safeguard to the VTEC system; it will only allow VTEC to engage if there is sufficient oil pressure. VTEC only engages at higher RPMs so the engine should not spit and sputter at idle; it may well stumble at high RPMS or, if the computer is in limp mode it may engage an artificial rev limiter much lower than your redline - which would cause the car to sputter once you hit that RPM. This is to protect your engine if the computer detects a serious problem.
If you do not trust the dealer (my local Honda dealer is the worst ever) then get a second opinion. Have your CEL code read, you can do this for free at Advance or Auto Zone or whatever auto parts store you have in your area, or you can buy an OBDII code reader for yourself, but they are fairly expensive. Or take it to an independent mechanic that has a good reputation for working with imports in your area.
