Po 431 means one of two things. One the second cat is going out. Or mass air flow is sending high signal to the pcm. Even though the car might run good. It would be a great idea to replace it. This code pops up if you have more then 100k. Catillic converter usually should be change at this time anyways second cat can be bought chep. Use a universal one despite what the dealer might tell you, it would be perfectly fine. You want to check the g/m on the mass air flow sensor or just simplify clean it out using a mass air flow cleaner..
Catalytic converters contain something called platinum or rhodium or palladium flakes. Here is a quote from the Related Link: "Catalytic converter -- an integral part of vehicle emission control systems since 1975. Oxidizing converters remove hydrocarbons and carbon monoxide (CO) from exhaust gases, while reducing converters control nitrogen oxide (NOx) emissions. Both use noble metal (platinum, palladium or rhodium) catalysts that can be 'poisoned' by lead compounds in the fuel or lubricant."
The 2005 Audi A4 Quattro 1.8 Turbo typically has one main catalytic converter, which is integrated into the exhaust system. Some models may also have a secondary catalytic converter, depending on specific configurations and emissions requirements. It's always best to consult the owner's manual or a professional mechanic for precise information related to your vehicle.

Yes, the 2007 Ford Fiesta is equipped with a catalytic converter. This component is part of the vehicle's exhaust system and is designed to reduce harmful emissions by converting toxic gases into less harmful substances before they are released into the atmosphere. If you're experiencing issues with your vehicle's emissions, it could be related to the catalytic converter.
A code P0455 indicates a large leak in the evaporative emissions control system, not necessarily a bad catalytic converter. While a malfunctioning catalytic converter can cause various issues, this specific code is more likely related to problems with the gas cap, fuel lines, or other components of the emissions system. It's important to diagnose and address the source of the P0455 code before concluding that the catalytic converter is at fault.
Yes, you can remove a catalytic converter, but it's illegal in many places due to environmental regulations, as it is an essential component for reducing harmful emissions. Cutting it out can also result in fines and penalties, as well as cause issues with vehicle inspections and warranties. Additionally, removing the catalytic converter can negatively impact your vehicle's performance and fuel efficiency. It's advisable to consult a professional or consider legal alternatives for any issues related to the catalytic converter.
That is the check engine light, see related question below.
Provided the catalytic converter, oxygen sensor and related components are good working order, no.
In Oklahoma, the removal of a catalytic converter can lead to fines and possible legal penalties, particularly if done unlawfully or without proper authorization. While specific fines can vary, individuals caught unlawfully removing a catalytic converter may face penalties under state statutes related to vehicle tampering and environmental regulations. Additionally, associated costs for restoring or replacing the converter may also arise. Always consult local laws for the most accurate and up-to-date information.
It can, yes. So can a bad fuel mix. Catalytic converters run hot to begin with, and dumping unburnt fuel into a converter can cause problems.It will mess with the O2 sensors causing premature failure.It can clog the converters and actually set the converter's internals on fire.See the related link for more information."An engine that is not performing properly, that is not burning all the fuel, will allow unburned or excess fuel to enter the exhaust system. When this excess or unburned fuel contacts the hot core of the converter it will ignite. This constant infusion of unburned fuel will cause temperatures to continuously rise above the designed operating temperature until the core of the catalytic converter will actually melt. Possible causes for the excess fuel entering the exhaust system are an incorrect fuel mixture, incorrect timing, corroded spark plugs, worn and cracked ignition wires, improper fuel pressure, a faulty oxygen sensor, sticking float, faulty fuel injector or a malfunctioning check valve."
Yes, the 2006 Kia Spectra typically has two catalytic converters. One is located in the exhaust manifold, and the other is situated in the exhaust system further downstream. This configuration helps to reduce harmful emissions more effectively. Always consult the vehicle's service manual or a professional mechanic for specific details related to your model.
To determine if the catalytic converter is bad or if it's just the bank 2 sensor, you can start by checking for warning lights on the dashboard, such as the check engine light. Use an OBD-II scanner to read any error codes; codes related to the catalytic converter (like P0420) indicate potential issues with it, while codes specific to the sensor (like P0138 for bank 2) suggest a sensor problem. Additionally, you can inspect the exhaust system for unusual noises or smells, and perform a visual check for physical damage or clogs in the catalytic converter. If the converter is excessively hot or glowing after driving, it may be failing.
