what is the code for the light staying on

I don't have that info. I'll see if I can find out from the dealer, however, you would think that their knowing that would have directed them to the problem. So far codes have detected: chewed wires, fuel sensor, and fuel injectors in that order.

yes, rats like to chew on wires

Especially the new soy-based ones they're making these days; seriously!

They may be stumped because the rats didn't tell them about ALL of the wires they chewed. AND I would never offer a rat a bite of my taco! If rodents and wires are involved , it will require patience , and yes yours is not the only situation like that unfortunatly.
