Mitsubishi Catalytic Converter: Diagnostic Clues and Troubleshooting Tips
Without the catalytic converter, the vehicle will be a much bigger source of air pollution. Through this device, toxic exhaust gases are converted into something much safer, resulting in reduced emissions. But like other parts of the exhaust system and car devices, the catalytic converter may also fail at this job when it gets damaged or some underlying cause leads to converter failure or deficiencies. Here are some clues to help you diagnose the Mitsubishi catalytic converter problem as well as some troubleshooting tips:
Rust buildup is the common enemy for exterior panels and components. The exhaust system is more susceptible to wear and damage caused by rust and corrosion due to its location. Exhaust system parts are heavily exposed to dirt, grime, road salt, mud, and moisture. When the car is driven in humid climates or in locations that are near the sea, ocean, or water bay, they're prone to developing rust. The catalytic converter may get ruined by this. Have the exhaust system regularly inspected. Check for rust buildup on the converter and other exhaust system parts to prevent the spread of rust. Apply anti-rust products for protection.
When the engine runs rich, or there's too much fuel and less air in the mixture, this can cause the failure of the catalytic converter. Unused fuel build ups and burns within the unit. As a result, the core of the catalytic converter gets damaged because of excessive heat. You must maintain a healthy fuel system to prevent catalytic converter damage and to keep the vehicle running efficiently.
When oil or fuel gets into the unit, the catalytic converter may fail. Most failures can be attributed to contamination due to a blown head gasket and other source of leaks. The leak must be traced and must be fixed. If the catalytic converter is severely damaged, it must be replaced to prevent problems that may arise from having a faulty converter such as toxic emissions, low fuel economy, as well as poor exhaust and engine performance.
The catalytic converter doesn't just fail on its own. There are other parts that may impact the function of the converter. Faulty head gaskets, worn-out 02 sensors, and busted spark plugs and wires can lead to the failure of the converter. When the check engine light comes on, figure out the cause right away, so you can fix the problem. This can save the converter from damage or wear. When the core of the catalytic converter fails, the core can't be fixed on its own. This will require full unit replacement.
When the catalytic converter fails
The catalytic converter doesn't have moving parts, so compared to other devices, the structure and design is not as complex. When it fails, the problem may not be isolated to this unit alone. This may be caused by support components and may be attributed to clogging, contamination, rust, and failure of other parts. Trace the underlying cause before you replace the unit. Otherwise, failure will recur.
