Check engine light low fuel level

Recommended Posts

First time this has happened to my 2017 Denali duramax.  My truck has 65k miles.  I ran under a quarter tank for a week or so as I was not driving it far. 


I first noticed it as my truck would not use the remote start.  


After I filled my tank it was gone.


I ordered a code reader so I have not looked to see if it has any codes yet.

The check engine light came on when the fuel was low and went out when I filled it up.   The low fuel warning does work.


The CEL could of been from something else and it was just a coincidence?


I currently have no CEL on my dash


I pulled codes this morning and it did find code P133B


Looks like a glow plug issue or a software update is needed.
