the vtec solenoid is by the back side of the valve cover not too far from the distributor. They work off of the computer sending a signal to open an oil passage to change the cam timing. If the computer sends the signal but doesn't see the cam timing change it sets the code. many times, dirty oil, low oil, wrong oil viscosity or a dirty oil screen can cause the cam timing not to change to what the computer is looking for. Once that happens and the check engine light comes on, the engine my run in "limp more". Engines runs but in a protected mode to keep the engine from damaging itself.

so, check your oil first thing. Make sure you are running the correct weight oil. It isn't real dirty. Oil level is in the correct level on the dipstick. If that is all okay, start checking out the vtec solenoid.
