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.

Check engine light shouldn't set for low fuel but the check engine light will disable remote start.

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.
