The Honda uses one wire that controls a solenoid. Ive never looked at our solenoid, so I dont even know how many wires there are. If it only uses one wire, Id guess its changed by a certain resistance, much like how Chrysler has a one wire door lock system (680 ohm to unlock - 1500 ohm to lock - or something like that)
Ive often wondered if this would work too...
Can the AFC even control our fuel or does the 02 go into open loop or something??
