On Board Diagnostic Light

[LBz074x4]

The light came on today i'm not sure what it means i read the om & that didnt tell me anything. I filled up with diesel the other day & while i was filling up i happened to look at the sticker on the pump it said low sulfer diesel instead of ultra low could that have caused it? also i cleand my afe & i looked in the afe housing and it looked like oil was in the bottom of it did it drain out? Any answers?

the diesel has nothing to do with this. the low sulfer is ay better for the pickup anywhy. im guess it wasnt low sulfer though they just never changed the sticker becasue you cant sell on road low sulfer diesel anymore. cleaning the air filter should be the issue. probably thorugh the sensor in the air intake. some people have had problems iwth this in the past with aftermarket air intakes

i dont know. yes ia the maf, many people dont know what it is so i jsut say sensor then they can figure it out. its worth a try, i dont know if there is a way to override either without something like efi live.
