For a high-performance minivan like a Toyota Sienna, only good things are expected to come from it. Thus, a Sienna that emits toxic gases could be an absolute turn-off. If your minivan has been producing bad gases lately, then it could be due to a poorly maintained Toyota Sienna catalytic converter assembly. A well-functioning catalytic converter saves the environment more than reducing plastic waste. This component is responsible for transforming your minivan's gases into less harmful chemicals, before they are released to the air. Once it wears out due to age or other factors, finding a high quality Toyota Sienna catalytic converter replacement is your next best move.

Frequently Asked Questions Ask APW

How many miles are covered by an emissions warranty for a Toyota Sienna catalytic converter? Answer: The catalytic converter (or cat) of a Toyota Sienna is covered by an eight-year or 80,000 miles emission warranty. Until then the dealer can replace the cat if it wears out within the warranty coverage. But if the cat breaks down after the warranty has expired, replacing it with a high quality yet affordable aftermarket catalytic converter is the next move. Take note, however, that if the cat is replaced with an aftermarket part while the warranty still covers it and it wears out, the manufacturer of the aftermarket part should be held accountable for the product's replacement or repair, and not Toyota.

How would anyone know if the Toyota Sienna's catalytic converter assembly has failed and has to be replaced? Answer: If the catalytic converter becomes clogged or poisoned, then it should be replaced immediately. Clogging and poisoning are usually caused by using leaded gasoline or overusing certain fuel additives. Fouled plugs may also cause unburned fuel to enter the catalytic converter and overheat it. In this case, replacing the catalytic converter of the Toyota Sienna can prevent the problems from worsening.

The "check engine" light is on, and the Toyota Sienna's catalytic converter shows a P0420 code on its oxygen sensor. What does this code mean? Answer: The code P0420 indicates that the catalytic converter of the vehicle is operating below its threshold. This is often due to a bad O2 sensor, but it does not mean it needs to be replaced immediately. Checking the exhaust for leaks--specifically in the manifold and the pipes--is advised. If the O2 sensors are perfectly fine, but the "check engine" light won't turn off still, have it checked by an auto mechanic to have the engine and the catalytic converter decarbonized. This is a process to remove the carbon build-up that may be causing the catalytic converter to fail.
