Kia-Sedona-Catalytic-Converters

Maintain the health of your Kia Sedona exhaust system with a capable catalytic converter. Converters are designed to regulate emissions, and they perform important tasks for cars and the environment alike. By helping you travel while keeping your environmental fingerprint small, converters represent a win-win situation for you and the planet.

How do catalytic converters work?

As Kia engines go about their business, they burn a lot of fuel. When these substances combust, they break down into several gases. Catalytic converters capture noxious exhaust fumes as they make their way from motors to mufflers. Inside converters reside a maze of passages lined with special metals. As exhaust gases force their way through this internal maze, the alloys react with the gases, nullifying them along the way. Harmful gases like carbon monoxide and nitrogen oxide thus meet their match.

How many kinds of catalytic converters are there?

Common kinds of converters include two-way, three-way, and four-way.

  • Two-way converters effectively deal with up to two separate pollutants.
  • Three-way converters up the ante, reacting with up to three common pollutants that include CO, HC, and small particles.
  • Four-way designs are used on diesel motors and combat the effects of up to four separate environmental hazards.
Are there any Sedona sensors you may need to replace?

Yes. Exhaust systems keep careful tabs on the chemical composition of emitted gases to get important feedback about fuel/air mixture levels and other key performance metrics. To get these readings, Kia Sedonas use electronic control modules (ECM) to sample values from various exhaust sensors. These include:

  • O2: Your Kia motor maintains a precise ratio between the air and the fuel in the combustion chambers. If this ratio changes by even a small amount, key systems including the catalytic converter face serious damage. Oxygen sensors sample the O2 levels in the exhaust stream and feed this vital information to the ECM for processing.
  • Temperature: Catalytic converters are tough components but are also susceptible to heat damage. Emissions system temperature sensors give the ECM information about converter heat levels, allowing it to make precautionary adjustments.
  • Nitrogen oxide - Some kinds of diesel engines produce large quantities of the poisonous gas nitrogen oxide. The NO sensor keeps tabs on this gas and allows the motor to make adjustments.
How can you diagnose catalytic converter damage?

Several sensors support converter operation, and you can usually access these sensors by attaching a diagnostic tool to the OBD-II port. Any faults display as specific codes that tell you exactly where to look for problems. That said, failing catalyzers tend to cause certain symptoms that you should be aware of, including:

  • Loss of fuel efficiency.
  • Loss of power.
  • Unusual emissions.

If you notice any of these symptoms, it may be time to have your Kia Sedona catalytic converter inspected.
