Ford knox sensor

[ACZL]

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 which I find hard to believe. If that's the case, what are we supposed to do to prevent gelling in winter months?

That's what's printed on repair order and it's related to emission system so IMO I really think it's supposed to be nox , but again that's what's written down on paper I was given.

Stop using the aftermarket fuel additives. You are told why your check engine light comes on. Diesel fuel already is formulated to prevent gelling right out of the pump. Isn't science amazing?
