Catalyst system low efficiency bank 2
When it gets below that threshold, the P0420 (System Efficiency Below Threshold) code will appear, which usually happens around 92% efficiency. Causes of P0420 and catalytic converter damage As we discussed earlier, inside a catalytic converter is a honeycomb type structure that looks like screens stacked one after the other that run the length ...Yes, Low O2 being seen in the Rear O2 sensor would tell the computer its running very clean and the Catalyst is efficient. The Rear O2 sensor was put into OBDII for the sole purpose of monitoring catalyst efficiency, nothing else. So if it reads low levels of O2, then it thinks the catalyst is working within specs and no CEL.
