Nice point, Sburn! I vaguely remember someone posting that there WAS a sensor somewhere, but I don't think I ever saw anything more about it (so it got filed in secondary memory).

It really makes sense doesn't it, that if one of their vehicles has the sensor, all flexfuel ones would have it? I guess Bill would know for sure, or, perhaps one of the techs on the forum?
