What does a p0157 mean on a catalyst?
If you have a P0157, that doesn’t mean your catalyst is bad (in fact, it usually never does). This code basically means that the Bank 2, Sensor 2 (or second o2 sensor back on bank 2) signal voltage is below what is considered normal for that sensor.
What causes p0157 to set on rear O2 sensor?
If the PCM determines that the post-cat o2 sensor signal voltage is below a certain threshold for too long, P0157 will set. Usually rear o2 sensor problems won’t cause drivability issues since they are an input that measures catalyst efficiency (unlike front o2 sensors).

What does Bank 2 mean on a Chevy Silverado?
We’ll cover those below. Bank 2 refers to the side of the engine with Cylinder 2 in the firing order. Sensor 2 is downstream of the catalytic converter. Typically, the only symptom of P0157 is going to be the service engine soon light. Sensor 2 is mostly about checking to see that the exhaust has been scrubbed by the catalytic converter.
