Check Engine Fault

Hopefully you're checking more than just the oil..

The light could mean anything from a buggy sensor to worse. If you're a company driver let the dispatch know and get to a shop before it becomes a real problem.

The last truck i had (2017 volvo), check engine light was on at 30 miles... brand new right? I wouldn't panic just yet, but if a STOP light comes on then something is definitely wrong.

 

Did you look in the computer to see if any faults show to you?
Otherwise.... It has to be hooked up to a computer at the shop.

 

There are literally hundreds of reasons why you could be showing a CEL. And, unfortunately, I don't have my diagnostic dice with me today, so judging from afar is going to be a bit... difficult.



Your best bet is to have it hooked up and scanned for DTCs.

 

Dude, with my truck, I need those dice. Bad.

 

To obtain those, you must go on a quest to a place of mystery and awe...



Protip: do not go to that website after drinking. You will end up buying some weird #### and having no idea why when it shows up.

 

As long as the answer is something OTHER than "aftertreatment" it'll pay for itself in short order.

 

I did a search on amazon for diagnostic dice. I came up with: https://www.amazon.com/Better-Livin...d=1526486962&sr=8-17&keywords=diagnostic+dice

 

If it’s a DEF truck it’s probably something with the emissions and will clear itself, I had a 2015 freighter that always did it. Check coolant too.

 

Google the code.
