The converter will need to be replaced with a new one. There is no method to clean them.

Why the problem with 02 sensor slow during catalyst monitor


Worn out Converter
Worn out O2 Sensors


Oxygen Sensors get replaced when they fail
& if they don't, you replace at 100,000 miles,
as they slow down (switching times)

They won't switch much, if their is little oxygen in
a failed converter,13 years, it's done

Catalyst Efficiency


Who installed the new one? Muffler shop or? Why did you replace catalyst in the first place? Emissions test failure?

Code p431 and p421


P421=Warm up catalyst system efficiency below threshold, bank 1
P431=Warm up catalyst system efficiency below threshold, bank 2
Sounds like you may have clogged or damaged catalyst converters or bad 02 sensors.
Those codes I think are taking from after the catalyst by the sensors in the exhaust pipes. Be careful taking it to a mechanic for further checking since the catalyst converters are not cheap through them. If you need to replace the converters, shop around and get prices on aftermarket parts. Don't be ripped off by a hungry mechanic or especially a dealer.

What would cause a 2003 chevy trail blazer to drive sluggish and the rpm not go above 3 even when the gas peddal is all the way to the floor?


The Catalytic converter, sounds like the converter is stopped up, have that checked out. You can get an idea by (starting with the engine cold) start the engine and run it for 8 - 10 minutes then feel the exhaust pipe going into the converter and then going out of the converter (you will have to get under the car enough to feel the pipes). if it is clear and normal- the pipes will feel the same temp (a little hot to the touch), but if the converter is stopped up, the inlet will be much hotter than the outlet.

Locate the 4 O2 sensors


You may only have 2 sensors. Follow the exhaust from the manifolds back. If there are four you will find them but I think you only have the two. Before and after catalyst, left bank and right bank if you have two converters.

1999 beetle P0422 which O2 is bad the o2 before the cat or after


P0422 - Catalyst below threshold.

Catalytic converter is clogged or out of medium.

Replace it.


ACTUAL DIAGNOSTIC:

Fault Code Definition
Code P0422 indicates that the Bank 1 Main Catalytic Converter's emissions efficiency has fallen below the minimum allowable limit. This threshold is tracked by a Catalyst Monitoring Oxygen Sensor located on or near the outlet of the Catalytic Converter.

Symptoms

* Check Engine Light will illuminate
* In many cases, no abnormal symptoms may be noticed

Common Problems That Trigger the P0422 Code

* Defective Catalytic Converter
* Engine misfires have damaged the Catalytic Converter
* Internal engine damage resulting in high oil consumption and/or a leaking Head gasket has damaged the Catalytic Converter

Common Misdiagnoses

* Oxygen Sensors are replaced when the real problem is a damaged Catalyst
* Catalyst is replaced when the real problem is internal engine damage, which is producing elevated emissions levels
* Catalyst is replaced when a misfiring engine is the real problem
