W20D with intermittent check engine light

[Denniscw]

Driving home from Huntsville stopped and purchased fuel at Pilot and not saying that was the problem but the check engine light came on. The light would come on with the buzzer, stay on for a minute or two then turn off. After driving for a while it would again come on for a while then turn off. Did not notice any power or problem. Has anyone had this situation with a Work Horse chassis.

Did you check the oil level? I don't know if there's a sensor or not, but that comes to mind first.

I can't recall if they have a vented fuel cap or not. If not, make sure it's there and tight. I think it's vented as I left mine behind a while back and no codes or warnings - replaced it the next trip.

Some of the auto parts stores have a code reader for obd2 - you could hook one up and see what shows up.

the 8.1l dos have a oil censer in the side of the oil pan to tell when there is low oil

but not sure if it would do any thing but no start?

we mostly get a dig dig dig but a buzzer ... is the that jacks ????? some one would know here
