[QUOTE="astroboy, post: 643199, member: 4527"] Variable Valve Timing a.k.a. VVT a.k.a. VTEC a.k.a. Campro a.k.a. etc.. is actually to advance timing in certain driving condition allowing extra valve clearance to gain more power when necessary. Some are engine RPM driven while some are engine vacuum driven. Imagine VTEC to activate at 6k rpm, unplugging the wire will disable it. It becomes an Honda City iDSL from a iVTEC.. :4: The wire you unplug is the can shaft position/angle sensor, not knowing the cam shaft angle, it will definitely trigger limp mode. But why unplug it?
