One way to promote a sustainable environment is through the reduction of harmful emissions from a growing number of vehicles. Your Mazda Protege's catalytic converter is the one responsible for turning the hazardous gases produced by your car into less toxic gases. When your vehicle's catcon gets worn or damaged, you'll notice dark, harmful gases emitted by your Protege. Aside from adding to the pollution, a broken catcon may also damage the car's exhaust system. In order to pass a smog test, which is a must in some states, and an emission test, installing a high-quality catalytic converter is highly recommended.

Frequently Asked Questions

Ask APW
  • Can a Mazda Protege still be driven even with a broken catalytic converter?

    Answer: Yes, the catalytic converter doesn't affect the engine's operation, making the Protege functional even with the catcon broken. However, running on a damaged cat or driving a vehicle without a cat converter is against the law in many states.
  • How can the catalytic converter in a Mazda Protege be cleaned?

    Answer: The catalytic converter in a Mazda Protege can become dirty or worse, clogged, when carbon has built up inside it. Removing the accumulated carbon inside the catcon can be done by retarding the injection timing to the bottom of the graph. This heats up the catcon and burns off the carbon buildup inside it. Keep in mind that the timing should never be set below the red line’s bottom in VAG-Com. This will melt turbine wheels because of the too retarded timing.  
  • What are some care and maintenance tips in for a Mazda Protege catalytic converter?

    Answer: Though catalytic converters don’t require maintenance of their own, their long-term service depends on proper care and maintenance of the vehicle. One way to prolong a catcon’s lifespan is to inspect it immediately once a Service Engine Soon or a Check Engine light appears. This prevents expensive damage to the cats and eliminates premature cats replacement.
  • What are the symptoms of a Mazda Protege’s broken catalytic converter?

    Answer: Some signs that a Protege’s cat converter is damaged include a sudden drop in fuel efficiency and failure in accelerating when the gas pedal is stepped on. Another indicator of a broken car is the vehicle’s refusal to start. But the most obvious symptoms are failed results in an emission test and appearance of the MIL or Check engine light. These problems are most often caused by a clogged catalytic converter in older cars, making it impossible for the gases to pass through the muffler and out of the car. In some cases, a malfunctioning cat is a result of a damaged cylinder head gasket, allowing oil or coolant to get into the combustion chamber and be burned in the cylinders. When the signs mentioned start showing up, it’s best that the catalytic converter be replaced immediately. Doing so prevents further damage and helps reduce air pollution in the environment.
