It means that the catalytic converter is not working like it should. It will probably have to be replaced. A misfire concern or leaking injector can cause this.

Code p0430


The oxygen sensor will not cause this issue. If the O2 sensor was bad, it would have a differant code. The engines computer is pretty good at testing the catalytic converters. GM does not want to replace one under warraty unless its bad.
The good news is that this should be covered under warraty. The catalytic converters are under factory warranty for 8 years or 80k miles. Unless the car was bought before this date in 2003, then it should be covered.
The spark plugs are good for 100k miles and do not need to be replaced at this time. I have seen them go pass this mileage and still have normal operation.
Let me know if you have any more questions on this issue.

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.

The low efficiency bank 2 means that the material inside the catalytic converter is deteriorating and needs to be replaced. FYI. Bank 2 refers to the side of the motor with cylinder number 2 on it.

Hard to start


P0430 Catalyst System Efficiency below Limit - Bank No 2" How would I fix that without taking it in? P0430 - Catalyst System Efficiency Below Threshold (Bank 2)
you need a scan tool to monitor the upstream and downstream 02 sensors on bank 2 more than likely its the converter. also check for exhaust leaks before converter . Most times the problem is the Downstream O2 sensor2_bing.gif is defective.

Code PO42O and PO43O ? Anyone know what they


The meaning of: P0420 Catalyst System Efficiency Below Threshold on Bank 1 P0430 Catalyst System Efficiency Below Threshold on Bank 2

Basically the Oxygen sensors ( one before and one after the catalytic converter ) have abnormal readings from the exhaust. Further diagnosing will need to be done by a mechanic to find the source of the problem. The possibilities could be the O2 sensors themselves, a leak in the exhaust manifold, a bad catalytic converter, and etc.
