Bank 2 is whatever side of the engine that doesn't contain cylinder 1 in it. Bank 2 Sensor 2 is located after the catalytic converter on bank 2. Sounds to me that the B2S2 (Bank 2 Sensor 2) is doing its job. It's the cat that can't clean up the emissions for whatever reason.

What does P0420 bank 1 code mean?
Code P0420 means "Catalyst System Efficency Below Threshold (Bank 1)" P0420 is actually Catalyst System Efficiency Below ThresholdCatalyst System Efficiency Below Threshold. Bank 1 is the side of the engine with cylinder #1. This code means that the catalytic converter is not cleaning the exhaust properly or the oxygen sensors are sending false info to the computer.

What does the code P0420 mean in a 2001 Dodge Stratus with 2.4 engine?
Catalyst efficiency below threshold, your catalytic converter may have failed.Catalyst efficiency below threshold, your catalytic converter may have failed.
What does code p0420 mean?
Code P0420 means "Catalyst System Efficency Below Threshold (Bank 1)" P0420 is actually Catalyst System Efficiency Below ThresholdCatalyst System Efficiency Below Threshold. This means that the secondary O2 sensor detects that the catalytic converter isn't working as efficiently as it should. This engine code can be triggered by any one of the following:1.) The catalyst in the catalytic converter is cracked, clogged, or otherwise damaged.2.) The secondary O2 sensor is malfunctioning.3.) There is an exhaust leak.4.) The computer unit is faulty.Trouble code P0420 means: Catalyst Efficiency Below Normal (Bank 1)

P0420=Catalyst System efficiency below threshold
What does engine code P0421 mean?
P0421 code = Warm up catalyst efficiency below threshold, Bank 1
Your check engine light says catalyst system below operating threshold what should you check first?
Check for exhaust leaks, check O2 sensor functionality, replace catalyst.

How to fix PO106 trouble code?
Catalyst Efficiency Below Threshold (Bank 1). If there is no other engine problems, you may have to replace the bank 1 catalytic converter.
What is check engine error code P0420 on a 2001 Sienna?
PO420 Catalyst System Efficiency Below Threshold. I believe it is catalyst system efficiency below threshold, bank 1. That is one option. Toyota had a problem with the ECM (Engine Control Module) giving this false code and manufactured a new ECM to eliminate this problem (ie. old part number 89661-0861 to new part number 89661-08062).
