OBD2 Code P2001
Strange. I don't even have a code for P2001 "NOx Trap Effeciency below threshold bank 2". So I can't tune it out in HPTuners. The C6 codes do not list it.
What does this stupid code mean anyway?

Code P2001 doesn't exist for the Vette's. But I think it means code P2A01? That code relates to the Bank 1 Sensor 2 O2 (drivers rear).
BTW, I believe NOx and Particulate traps mentioned above are the new emission control devices that are going to be used on diesel engines.

Checked my service manual and P2001 is not in it. The trap is for diesel's.
