Research on Catalytic Converter for Toyota Sienna

One of the leading minivans in today´s market, the Toyota Sienna delivers a safe, reliable ride with good fuel economy. In designing the Sienna, which was introduced in 1997, Toyota borrowed a modified front-wheel-drive platform from the Camry, giving passengers the feeling of riding in a car rather than a van. The Sienna was initially praised for its handling, but it lacked many of the features the best-selling minivans offered. Subsequent Sienna's were better equipped, offering advanced features like traction control and Bluetooth connectivity. When the third-generation Sienna went on sale in 2010 for the 2011 model year, it was named a Top Safety Pick by the IIHS. The third generation also brought an extensive makeover, which closed the gap between the Sienna and its competitors. The Sienna now ranks as one of the best-selling minivans in the U.S.

The catalytic converter was a 1970´s innovation that helped cut down on pollution from automobile exhaust. A properly functioning one has been mandatory in cars since 1975.

What should I do if my catalytic converter fails?

A catalytic converter should never fail. If it does, then there is a problem that will not be fixed by simply replacing the converter. Its failure is the result of a less apparent problem under the hood.

What are some catalytic converter problems?

Whenever an engine is operating outside of proper specifications, your converter suffers unnecessary wear and damage. The wrong fuel/air mixture, incorrect timing, or misfiring plugs can lead to catalytic converter failure.

What is a catalytic converter meltdown?

Fuel that leaves the combustion chamber unburned will enter the exhaust system. When it reaches the converter, this excess fuel can overheat the converter, causing a converter meltdown, which happens when the converter overheats due to a raw fuel condition in the exhaust flow. The unburned fuel ignites when it hits the hot ceramic catalyst and drives the temperature far above normal. The ceramic catalyst cannot withstand this extreme heat and begins to melt until the ceramic collapses and the converter is destroyed. The overly rich condition that led to the meltdown could be the result of a faulty oxygen sensor, an incorrect fuel mixture, worn spark plugs or wires, a faulty check valve, incorrect ignition timing, or faulty fuel injectors.

What else can cause a meltdown?

Faulty spark plugs cause unburned fuel to enter the exhaust system. The unburned fuel ignites inside the converter and can result in a partial or complete meltdown of the ceramic catalyst. Spark plugs and spark plug wires should be checked regularly and replaced if damaged or if wires are worn or cracked.

Can a catalytic converter break?

Road debris striking the converter can cause a catalyst fracture. Once the catalyst is fractured, the broken pieces become loose and rattle around and break up into smaller pieces. Flow is interrupted and back pressure in the exhaust system increases, leading to heat buildup and loss of power

What is a catalytic converter's replacement cost?

Repairing or replacing your Toyota Sienna catalytic converter can cost close to $2,000, but PartsGeek may have a better deal. PartsGeek has Bosal catalytic converters for the Toyota Sienna ranging from $197-$302 for models that are legal in all states except New York and California, and from $62-$115 for those that are legal in all states.
