Several of us have had this. TSB 17-NA-105 advises updating ECM firmware. Firmware has been updated to adjust criteria for a number of DTC's including P013B. Looks like they had some test parameters dialed in a little too tight.
Hopefully that's it - no real problem. Mine has been fine since the update.

Thanks, under warranty so I'll just take it in. How long does this fix usually take?
