Nissan Juke Catalytic Converter (2010-2019)

The catalytic converter in the Nissan Juke is a three-way catalytic converter integrated into the exhaust system. Its primary role is to chemically transform toxic exhaust gases into carbon dioxide and water by these chemical reactions. It reduces nitrogen oxides (NOx), unburned hydrocarbons, and carbon monoxide emissions to help the vehicle meet Euro 5 emission standards.

The catalytic converter uses two main chemical processes:

• Oxidation catalysis that burns hydrocarbons and carbon monoxide using platinum and palladium catalysts.
• Reduction catalysis that reduces nitrogen oxides (NOx) using rhodium or platinum catalysts.

Inside, it contains a honeycomb structure of micropores that help retain, filter, and convert harmful particles at an optimal combustion temperature of around 420°C, which is why it is located close to the engine.

The catalytic converter typically weighs between 1 to 10 kilograms and can be positioned in different ways:

• Placed directly under the vehicle
• Adapted to the exhaust manifold, where gases are hottest
• Integrated into the manifold itself for maximum temperature efficiency
• Close-coupled catalytic converter, which is a recent design directly attached to the manifold connection

The Nissan Juke is equipped with these types depending on the engine configuration and model variant, including the Nismo version with additional performance exhaust sections.

Catalytic converters contain precious metals such as platinum, palladium, and rhodium, which enable the chemical reactions needed to reduce emissions. These rare metals give the converter significant scrap value, typically ranging from $200 to $340 for used Nissan Juke diesel converters, based on market rates as of early 2026.

• Precious metal coatings enable high catalytic efficiency
• Valuable for recycling due to contained metals

This explains why the catalytic converter is an important and valuable component of the vehicle’s exhaust system.

Signs of a faulty catalytic converter include:

• Opaque smoke from the exhaust
• Metallic noises or strong vibrations beneath the vehicle
• Reduced engine power or sluggish acceleration
• Engine stalling frequently

Common causes of failure include melting of the internal monolith due to excess fuel, soot clogging the catalyst, and incorrect upstream sealing or gasket use.

Comprehensive illustrated manuals and step-by-step video tutorials are available to guide users through replacing the catalytic converter on Nissan Juke vehicles. Replacement parts meet all standard regulations including Euro 5 emission compliance.

• Installation manuals and expert technical support are offered
• Quality-assured replacement catalytic converters are available, including direct fit options
• Professional installation is recommended along with replacing associated gaskets and sensors

Regular engine checks and proper fuel use (no leaded petrol) are essential to prolong catalytic converter lifespan.

The Nissan Juke catalytic converter must be used with unleaded petrol only, as leaded fuel can damage the converter. Also, the vehicle’s engine and exhaust system are designed to meet Euro 5 standards for emissions.

• Use only unleaded petrol fuel to avoid converter damage
• Replace Lambda sensors when changing the catalytic converter, typically every 80,000 to 100,000 km
• Ensure proper sealing with copper gaskets in exhaust connections

Following these requirements helps ensure optimal emissions control and converter longevity.
