Mazda B2600 Catalytic Converter

Symptoms of a Faulty Mazda B2600 Catalytic Converter

Because of your catalytic converter, your vehicle's harmful exhaust emissions are reduced by an ample percentage. However, with all the heat that your catalytic converter is regularly exposed to, this vital component of your exhaust system may eventually fail. Know how to diagnose and troubleshoot your Mazda B2600 catalytic converter troubles by taking note of the following:

Increased emissions of exhaust gases

Increased emissions of carbon monoxide (CO) and hydrocarbons (HC) mean that you have a fouled catalytic converter. A fouled converter is usually caused by lead, phosphorous, or silicone contamination. Lead used to be the most common contaminant when it was used as an ingredient in gasoline, but newer types of gasoline were able to eliminate this specific issue. On the other hand, contamination from the phosphorous in your motor oil or silicone in your coolant is still a major culprit behind a fouled catalytic converter. Try looking for any leaky valves, O-rings, or gaskets to know the root of your failed catalytic converter. To narrow down the source, see if white smoke is coming out of your tailpipe; this is most probably caused by a coolant leak.

Loss of power

Rough idling, acceleration problems, and stalling issues are just some of the problems that accompany a plugged or blocked converter. Any restriction in your exhaust system can lead to excessive backpressure and a choked engine. If you notice these symptoms in your pickup, then you should measure your exhaust backpressure using a pressure gauge or a vacuum gauge.

Poor fuel economy

Another symptom of a plugged catalytic converter is a decrease in fuel mileage. If your check engine light turns on and you notice that your miles per gallon is significantly reduced, then you might have a clogged catalytic converter. Examine your pickup for misfiring spark plugs or faulty valves, since these usually plug up your catalytic converter with too much heat or unburned exhaust gases.

Odd noises and foul odors

Unusually loud noises from your exhaust system is a sign of catalytic converter failure caused by internal damage. Due to the repetitive heating and cooling of your catalytic converter, the honeycomb structure inside it can become brittle and eventually collapse. Another symptom of a bad catalytic converter is a "rotten egg" smell from your exhaust system.

  • How to Make Your Mazda B2600 Catalytic Converter Last Longer

    Your pickup doesn't just let out more harmful emissions into the atmosphere when your Mazda B2600 catalytic converter starts to fail; it also becomes a lot more difficult to drive. The catalytic converter itself doesn't require periodic tune-up, but taking care of the rest of your pickup can help it last much longer. Here are some helpful reminders to ensure that your catalytic converter stays in good condition for as long as possible:

    Act fast when your check engine light turns on.

    Find out the problem with your vehicle the instant you notice your check engine light turn on. The check engine light might throw a code that is not related to the catalytic converter or even to the rest of your exhaust system, but resolving the cause of your illuminated check engine light can still extend the lifespan of your catalytic converter.

    Keep your pickup perfectly tuned.

    Your catalytic converter might not need regular maintenance, but it will certainly benefit from a perfectly tuned engine. An engine that gets a tune-up on a regular basis produces the proper air-fuel mixture for optimum combustion. This also means that your catalytic converter has less chances of being overworked, overheated, or plugged.

    Regularly check on the major causes of catalytic converter failure.

    Check and repair the other components in your pickup that might contribute to a fouled or plugged catalytic converter. These include faulty or misfiring spark plugs, bad oxygen sensors, blown head gaskets that result to internal coolant leaks, motor oil leaks, and many more.

    Visually examine your catalytic converter for physical damage.

    Rust can also be a problem for your catalytic converter, so make sure to inspect your catalytic converter for signs of corrosion. If you see some rust spots on your cat converter, treat them immediately with some rust remover to prevent them from getting worse. Check if the honeycomb structure inside your cat converter is damaged as well. If the interior of your cat converter has collapsed, you will hear a rattling noise when you shake your cat converter.

    Lock up your catalytic converter.

    Because of the expensive components of your catalytic converter, it is also very attractive to thieves. Cat converter theft is especially common among pickups because their higher ground clearance makes their cat converter easier to access. Look for a cat converter lock to secure yours to your vehicle.
