Customer Question
The check engine light...

The check engine light came on and when I plugged in my INNOVA tester it showed a code that was either POIFO or PO1FO and I was trying to see what that code was for

Mechanic's Assistant: Does the light stay on, or does it blink?

Its a 2015 GMC Denali pick up 4x4 diesel

Mechanic's Assistant: What is the model of your '15 GMC?

Z-71?

Mechanic's Assistant: Are you fixing your vehicle yourself? What have you tried so far?

I just plugged into port to see what the code was and cleared the check engine light

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

I'm curious as to what the code is as I cant find it on my list. I'm guessing it MIGHT be low coolant level? I don't have any other issues or codes.
