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 ...

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?
Try telling that to folks in areas where temps get down to -30 to -20.
My son drives an over the road tractor trailer Chicago and north into Minnesota and Wisconsin and has yest to put anything in the truck but the fuel that comes out of the pump. The refiners put in anti gel additives as it leaves the terminal. You can buy all the snake oil you want and put it into your truck to set off the check engine light and ultimately lead to a shorter life of those sensors. Its your truck and your wallet. Your dealer told you to stop.
Many long hisl truck drivers that go from south to north in one tank need them because the fuel in the south doesn't have these additives.
Also, aside from California and Texas that have higher fuel requirements than the US federal standards, most states only meet the minimum federal diesel fuel standards of 40 octane and lower scar value. Not saying everyone needs it, but there are those that might.
