Catalyst - Check linkage between sensor and catalyst. How did you clear the memory? Did you use the code reader?

Definition of Diagnostic Trouble Code P0420 Category: Powertrain Definition: Catalyst System Efficiency Below Threshold Bank 1Note: This definition of P0420 is applied to all manufacturers

Definition of Diagnostic Trouble Code P0430 Category: Powertrain Definition: Catalyst System Efficiency Below Threshold Bank 2Note: This definition of P0430 is applied to all manufacturers

As the code description implies the P0430 code means that the vehicle's control module has detected that the three-way catalytic converter is not working properly (is not as efficient as the factory is expecting). Replacing the oxygen (O2) sensors may sometimes fix the code, but in most cases the catalytic convert needs to be replaced to fix the problem. If the P0430 code is combined with other codes, try fixing the other codes first.

Volkswagen touareg 2005, V6, 3.2L error code P0420, P0430 and P0068


Hi. Please concentrate on fixing p0068. this is to do with airflow and fuel/ mixture. maybe air mass meter. these can cause faults p0420 and 0430 to come on. after p0068 is repaired clear all faults and take the car on a long drive to clean out the cats, reassess if the cats are actually faulty at a later date.

Check engine light on with p0430, had it reset put some catclean in, drove for 150 miles about 160 mph check engine light did not come back on. But the p0430 comes up.


You didn't reset a thing

You cleared all data needed to diagnose the issue

Google your codes: OBD PO430

You will see you have a failed exhaust converter

Now you have to resolve the reason it failed,
before replacing it,they should last 15 years

Light just came on when started vehicle. Another code followed P0430. Vehicle seems to run fine. thanks


P0430 - Catalyst System Efficiency Below Threshold Bank 2

The ECM or PCM monitors the switching frequency ratio of heated oxygen sensors 1 and 2.

A three way catalyst converter(Manifold) with high oxygen storage capacity will indicate a low switching frequency of heated oxygen sensor 2. As oxygen storage capacity decreases, the heated oxygen sensor 2 switching frequency will increase.

When the frequency ratio of heated oxygen sensors 1 and 2 approaches a specified limit value, the three way catalyst (Manifold) malfunction is diagnosed.

Possible Causes:
- Three way catalyst converter Bank 2
- Exhaust tube
- Intake air leaks
- Fuel injectors may be faulty
- Fuel injector leaks
- Spark plugs may be faulty
- Improper ignition timing
- Engine Control Module

Possible Solutions:
The most common cause it the three way catalyst converter Bank 1.

If the P0430 is combined with other DTC's try fixing those first and this code may clear.

just a word of advice there is no sensor that tells you if you need a cat ! that code comes on because of faulty o2 sensors have you changed the 02 sensors yet ? if not change them reset ( clear ) the codes that code will come on a few times just keep resetting or clearing it i have had 2 co workers not listen to me and changed the cat 400-600 dollars and the code just comes back on one guy had the cat changed two times and the code came back after i reset the codes 3 times it stayed off it seems like its preset to come on around 100,000 miles with 02 sensor codes DONT LET THE MECHANIC SELL YOU A CAT hope this helps
