Here we are replacing our (bank 1 sensor 2) downstream O2 sensor which has prevented the PO420 code from returning. The code would trigger within 5 minutes of the car idling and although the car still ran great before replacing the sensor it is nice to no longer have that CEL.
If you decide to replace your sensor and the code returns it would most likely mean your catalytic converter is failing and will need to be replace.
