The purpose of a catalytic converter is to reduce harmful exhaust emissions to less noxious substances through a process of oxidization that depends on a variety of precious metals in the converter being at very high temperatures. If the individual sensor readings are too similar in response time or level, a code will be stored and a malfunction indicator lamp will be illuminated. I have started getting a P0430 code on my 2006 4. Either the oxygen sensor is faulty and is giving a incorrect reading,which means you must repalce it, or the catalytic converter is faulty, and must be replaced. Once you have triggered a it is likely that your O2 sensors will have carbon buildup and may not be reading correctly. Also, where did you get the o2 socket? I'd read that the 06 doesn't have a fuel filter, did you add one? That is how I discovered this forum.
If the original cause of converter failure is intermittent, only the catalyst failure code may show up masking the original reason for converter failure. When the frequency ratio of heated oxygen sensors 1 and 2 approaches a specified limit value, the three way catalyst malfunction is diagnosed. Common Misdiagnosis The most common misdiagnosis is caused by not thoroughly investigating what led to catalytic converter failure. This engine code can be triggered by any one of the following: 1. Step 1 If the converter is not covered by warranty, record all fault codes present, as well as all available freeze frame data. I wish you luck and be careful not to spend money quickly before you know for certain. Unlike some other brands, do not drive an Audi until it fails, then fix it.

I live in an emission tested area and it sucks when you can't get those codes gone! Those who have your best interest at heart and respect the car. I had someone read it with a bigger scanner and told me that it was bank 2 position 1. This can be confirmed by the fact that its temperature remains below 400 deg F 200 deg C even after expended periods of driving. This code means that the catalytic converter is not cleaning the exhaust properly or the oxygen sensors are sending false info to the computer. Note though that this estimate does not include taxes and fees that may be payable, nor does it include the cost of resolving underlying issues that may have contributed to the failure.
Some makes actually allow the use of cheaper catalyst, while others will not. Can't recall the code but the dealer originally 6 months ago said I needed 2 catalytic converters, which to me is crazy given the relatively low mileage. However, note that code P0432 can appear even if the converted has never overheated, such as in cases where the converter is no longer operating at peak efficiency due to long use. The O2 sensor is what reads the exhaust air to fuel ratio. It can be an exhaust leak, defective O2 sensor on bank 1, engine coolant sensor is defective, leaking fuel injector, cylinder misfire, or problem with wiring on O2 sensor. Starting with the O2 sensor. YourMechanic offers certified mobile mechanics who will come to your home or office to diagnose and repair your vehicle.
How do you troubleshoot code P0432? So, amazingly enough, Toyota gave me the same fix I read about elsewhere. If your are for a different car, select that vehicle series before searching for the diagnostic codes because not all used by one manufacture are used by the other makes. What causes the P0430 code? Once the delicate metals or ceramic materials inside the converter have been damaged, there is little you can do. Please keep us updated on whether or not your o2 changes fix your issue permanently. This is generally very difficult to do unless a vehicle hoist is available to be able to gain access to the exhaust system. We are not responsible for any actions you take on your vehicle.
I bought one last year and it has been wonderful. A three way catalyst converter Manifold with high oxygen storage capacity will indicate a low switching frequency of heated oxygen sensor 2. It works by switching much more slowly than the front O2 sensor. Volvo did an inspection after the Cat was installed and found the turbo flange was not quite flush, but it was too late after the install was done by other people. There are approximately 64 high resolution pulses for every cam pulse.
At this point if you take it into the dealer or your local mechanic they will probably recommend that you replace your. The outer bearing will fall off and the inner bearing and seal needs to be pulled of the shaft with your hand. I can clear it but it comes back in 3 days. The on-board computer in your car needs time to reset itself automatically. Diagnosing this code should be well within the capabilities of most non-professional mechanics, provided a scanner that can monitor live data streams is available, and that there are no other codes present. Many different systems and components can cause the P0430 code.
Often, leaks in these areas can cause the computer to inaccurately set the P0432 code. What are the common mistakes when repairing code P0432? Some say to change them all at once. Have your car diagnosed as soon as possible. If that is the only code you are getting and the car has high mileage 90k + , the odds are in favor or the front pre-catalyst needing replacement. There is an exhaust leak. 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. The Catalyst Monitoring O2 sensor, which is found near the outlet of the Catalytic Converter, is the one that tracks the threshold for the emission efficiency.
