Ford knox sensor
Have other folks had issues w/ Fords Knox sensors? If so, did your dealer tell you why it failed or triggered a engine light? Mine is telling me it's being tripped by using aftermarket fuel additives ...

I worked for a trucking company in Denver that ran to California daily. In the winter we had no issues from Denver West with our treated fuel. However, on return trips we had fuel issues coming over the mountains. Fuel jelled in tractors and refrigeration units. Drivers were instructed to add an additive east bound due to the California or Nevada fuel which was blended for the local temperatures. Some call it snake oil, we called additives a necessity.
