Hyundai Kona Catalytic Converter (2017-2023)

The catalytic converter in a Hyundai Kona is a key component of the exhaust system that reduces harmful emissions. It transforms toxic gases like hydrocarbons (HC), carbon monoxide (CO), and nitrogen oxides (NOx) into less harmful substances such as carbon dioxide (CO₂), nitrogen (N₂), and water (H₂O) through chemical reactions catalysed by precious metals including platinum, palladium, and rhodium. The converter activates at temperatures above 200°C and uses oxygen sensors before and after the converter to optimise fuel mixture via the engine control unit (ECU). A malfunction often triggers the engine warning light and puts the vehicle into a limp or reduced power mode.

The catalytic converter on Hyundai Kona vehicles typically features:

• A metal housing integrated into the exhaust manifold, containing a ceramic or metallic substrate coated with catalytic materials.
• Entrance fitted with oxygen (lambda) sensors and temperature sensors, and exit with a heating sensor to optimise operation.
• A three-way catalytic converter type primarily for petrol engines, which performs oxidation of CO and HC and reduction of NOx.
• For diesel engines, it is often combined with a Diesel Particulate Filter (DPF) and a Selective Catalytic Reduction (SCR) system using urea for NOx reduction.

The chemical process involves initial NOx reduction by rhodium and platinum, followed by oxidation of hydrocarbons and CO by platinum and palladium, using exhaust heat to maintain efficiency.

Common issues with Hyundai Kona catalytic converters include:

• Poisoning from fuel contaminants or leaded fuel.
• Overheating due to combustion or ignition problems.
• Triggered engine warning lights indicating failure and initiating emergency driving mode.
• Increased fuel consumption and potential failure of technical inspections.

Diagnosis is generally done via lambda sensor readings and OBD scans. Replacement is advised when failure occurs, involving removal of exhaust parts such as silent blocks, exhaust manifold, and associated gaskets and timing belts.

For performance tuning, especially in the Hyundai Kona N model, options include:

• Installing a high-flow catalytic converter or a wider downpipe to increase turbo efficiency and reduce backpressure.
• Combining these with upgraded intercoolers (e.g., AIRTEC) to boost power.

However, removing or heavily modifying the catalytic converter can lead to non-compliance with emissions regulations and failure to pass official inspections.

Catalytic converters contain precious metals such as platinum, palladium, and rhodium, which catalyse chemical reactions to reduce harmful emissions. These rare metals give catalytic converters intrinsic value beyond their function. Their efficient operation is crucial for meeting environmental standards and maintaining vehicle performance.

The price of a Hyundai Kona catalytic converter varies based on several factors:

• The specific model and engine variant (petrol or diesel, power output).
• Certification and manufacturing quality, with high-performance INOX 409 stainless steel and advanced coating technology generally costing more.
• Inclusion of sensors and associated components required for correct operation.
• Current market costs of precious metals contained in the converter.

Professional replacement services and diagnostics also affect the overall cost.

If your Hyundai Kona’s engine warning light indicates a catalytic converter issue, follow these steps:

• Perform an OBD diagnostic scan to read fault codes.
• Check for symptoms such as reduced engine performance or increased fuel consumption.
• Inspect related components like lambda sensors and exhaust system for faults.
• If confirmed faulty, arrange replacement of the catalytic converter with a certified part.
• Avoid ignoring the warning as this can lead to further engine damage and failed emissions testing.

Prompt professional service ensures the main pollution control system works effectively and maintains vehicle reliability.
