    How do hazardous compounds such as carbon monoxide, nitrogen oxide, and hydrocarbons turn into less harmful gases? Easy. Once these gases exit your car engine, they head on to your exhaust where an expanded tube awaits them and breaks them down into less toxic gases. This ceramic tube is the Toyota 4Runner catalytic converter. It consists of enzymes that hasten its chemical reaction with these compound gases to eliminate or reduce harmful emissions. It is important to always keep the catalytic converter in good condition. A bad converter can lead to poor engine performance and high exhaust emissions.

    Frequently Asked Questions

    Ask APW
    • How can a damaged oxygen sensor affect a Toyota 4Runner catalytic converter?
      Answer: Oxygen sensors and catalytic converters work closely with each other, but they have separate functions. The sensor evaluates the amount of oxygen in the exhaust and acts as an indicator if the air-fuel mixture is just right or inadequate. So when an oxygen sensor is broken, it does not necessarily follow that it will have a direct effect on the converter's performance. But failure to replace the sensor may eventually cause damage to the converter.
    • How much would the repair cost be for a damaged Toyota 4Runner catalytic converter?
      Answer: It depends if you are going to do the repair yourself or hire a mechanic to do the job. Of course, it's cheaper if you do it yourself. The price of Toyota 4Runner cats ranges from $50 to $400. But if you opt to go to a repair shop, you would have to factor in the expense of labor fees.
    • What are the causes of a poisoned Toyota 4Runner catalytic converter?
      Answer: One of the reasons for a catalytic converter failure is when it has become poisoned. The usage of leaded fuel or fuel additives that have lead is one of the causes of this poisoning. Defective engine sensors, failure in the engine system, and an out-of-tune engine can also contribute to the poisoning of a Toyota 4Runner catalytic converter. As a result, the converter loses its ability to efficiently manage emissions.
    • What are the ways of diagnosing a broken Toyota 4Runner catalytic converter?
      Answer: One way of testing the catalytic converter for defects is by removing the oxygen sensor and noting if there have been changes in the car's performance. If the performance seems to have become poor, the cats already need replacement. Another way is to measure the exhaust backpressure with a vacuum gauge or a pressure gauge. Simply connect the gauge to the converter through the emission test port or an adapter in the opening of the oxygen sensor. For the vacuum gauge, the engine vacuum should be measured at curb idle and at 1600 RPM. If the vacuum is gauged at 21 inches at curb idle and 15 inches at 1600 RPM, the converter is definitely defective and needs to be replaced.
