Mitsubishi Catalytic Converter Articles

Automobiles evolved with technology; at the same time, problems on vehicle-caused pollution continuously rose up through time. However, there have been various measures introduced to prevent the scenario from getting worse. One is the use of catalytic converters, which was initiated in the 70s. The US government has likewise, passed a law requiring the use of catalytic converters for gasoline-powered vehicles. Diesel-powered vehicles do not use catalytic converters.

Catalytic converters or simply called the "cats" can also be replaced like most auto parts. If you have a gasoline-powered Mitsubishi that needs replacement catalytic converter, it is important that you replace it right away to avoid harmful emissions. As the name implies, the Mitsubishi catalytic converter "converts" the harmful exhausts into carbon dioxide and water, which are not harmful to the environment when released from the vehicle.
 

Just like your car's engine, the Mitsubishi catalytic converter gets extremely hot while it works to clean the harmful exhaust gas. Thus, when the more harmful exhaust the engine produces, the hotter the catalytic converter can be. When your Mitsubishi catalytic converter gets too hot to the point of glowing because of extreme heat, it can easily be damaged. At this point you must be extra cautious of your catalytic converter. Symptoms of damaged cats are loss of power, heat coming out from the floor of the vehicle and sulfuric smell. Rusts may also develop since moisture may react with the iron in steel and iron oxide being produced.

If you are using leaded fuel for your Mitsubishi car or SUV, the catalytic converter can be more prone to damage since lead produces coating on the platinum honeycomb inside the Mitsubishi converter. Removing your car's catalytic converter is not permissible in almost all states; thus, if your Mitsubishi catalytic converter needs replacement, get a new Mitsubishi catalytic converter as soon as possible and have it replaced by an experienced mechanic.

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

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.

Engine buildup

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.

Contamination

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.

Failing parts

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.

Bad Throttle Body Symptoms

Bad Throttle Body SymptomsThe car’s primary computer, which is often referred to as the powertrain control module (PCM), expects to see a certain amount of airflow through the throttle body. When that doesn’t happen, because the throttle body is dirty or faulty, the engine may stall. Unstable idle

May 13, 2020
P0138 Code: O2 Sensor Circuit High Voltage (Bank 1, Sensor 2)All modern cars have at least two oxygen sensors. Although both sensors detect the amount of oxygen in the exhaust stream, the PCM uses the data they provide differently. The first sensor (or Sensor 1) is the upstream oxygen sensor that aids the PCM in regulating the vehicle’s air/fuel ratio.

Can You Drive Without a Catalytic Converter?Technically, yes. Older cars ran just fine before catalytic converters became commonplace in the 1970s. So, if your question is whether your car will run without one, then it most certainly will. But the other question you should be asking is—should you risk it?
