Fuel Gauge/Check Engine Light Question

[Cai]

Hello All,

I have a '13 SCREW, 186k mileage. Got a fresh oil change last week and when I got it back the check engine light was on, the fuel gauge read E, and the MPG digital readout is showing "--" (not calculating MPG). I'm assuming it needs a code reset or something similar. I would take it back to the lube shop to have them fix it but I'm traveling for the holiday and hoping it's something I can do myself in the software.

Any one have any ideas? All input appreciated.

Cheers!

Cai

Well, what CEL code is it throwing?

Any updates on this? Interesting how the problem developed after you "got an oil change" @Cai . Kinda makes you wonder what else might have "happened" during the visit to the shop. Was the truck left with them alone for awhile or did you wait in person at the shop?

I know, I know - conspiracy theory time...getting my tinfoil hat ready for the holiday season.
