Fuel induction service -> check engine light

[Wanderlust073]

I had the fuel induction cleaning done at Christian Bros a week ago. This morning the check engine light came on. I haven’t noticed anything running differently about the truck at all - not before, nor after the light came on. Taking it in tomorrow for them to check it out. Coincidence? Anything I should be aware of before they read codes?

I’ve generally found them to be a pretty honest shop, so I’m not too worried about it, but I would like to walk in as informed as I can be.

Any idea what the code was for?

I didn’t have time to hit an auto zone. Taking it to them 7a to find out…

Nothingburger(ish): P0128, Coolant Temp below thermostat regulating temperature.

I'll drop it off tomorrow night and it will give them something to do while 2 feet of snow buries us, lol.
