Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.

Code P013b indicates a fault with the oxygen sensor lean to rich sensor 2.This is a slow response signal from the post catalytic converter oxygen sensor or sensor 2 (second sensor from the engine) in the exhaust system.The sensor is pictured below and requires replacement when this code sets here.
