Hyundai Kona Catalytic Converter (2017-2023)

The catalytic converter in a Hyundai Kona is part of the exhaust system that transforms harmful gases such as hydrocarbons (HC), carbon monoxide (CO), and nitrogen oxides (NOx) into less polluting substances like carbon dioxide (CO₂), nitrogen (N₂), and water (H₂O). This conversion is achieved through chemical reactions catalyzed by precious metals including platinum, palladium, and rhodium. It activates at temperatures above 200°C and works with lambda sensors before and after it to optimize the engine's air-fuel mixture for cleaner emissions.

The catalytic converter is integrated within the exhaust manifold and housed in a metal casing. Inside, it contains a ceramic or metallic substrate coated with catalytic materials. It features an inlet with a lambda sensor and temperature sensor, and an outlet with a heating sensor. Hyundai Kona gasoline models typically use a three-way catalytic converter that oxidizes CO and HC while reducing NOx, while diesel variants may include additional DPF (diesel particulate filter) and SCR systems for enhanced treatment.

Common issues include poisoning caused by fuel or lead contamination, overheating, ignition or carburetor malfunctions which can trigger the engine warning light and cause the vehicle’s ECU to enter limp mode. Symptoms may also include increased fuel consumption and failing emissions tests. Replacement is often necessary when these faults appear.

• Engine warning light activation
• Vehicle going into limp mode
• Increased fuel consumption
• Failed emissions or technical inspections

Diagnosis is typically via lambda sensors measuring emissions upstream and downstream of the catalytic converter and requires an OBD scan when warning lights are on.

Replacement usually involves removing components such as the silent blocks, exhaust manifold, heat shield, and sometimes the DPF depending on engine type. Related parts like gaskets and timing belts may also need inspection or replacement. The process follows strict safety and installation guidelines to ensure optimal function.

• Remove silent blocks
• Detach exhaust manifold
• Replace any damaged gaskets
• Install new catalytic converter and sensors
• Reassemble parts carefully

It is highly recommended to consult professional tutorials or seek expert service to perform this procedure for the Hyundai Kona.

Some tuning options for Hyundai Kona, especially the Kona N model, include upgrading to high-flow catalytic converters or installing a larger downpipe to reduce exhaust backpressure and increase turbo efficiency. These modifications can boost power output and throttle response when combined with upgraded intercoolers or air intake systems.

• High-flow catalytic converters
• Larger diameter downpipes
• High-performance intercoolers (e.g., AIRTEC)

However, complete removal or disabling of the catalytic converter is illegal as it compromises emission standards and will cause failure in technical inspections.

Catalytic converters contain precious metals like platinum, palladium, and rhodium which act as catalysts for chemical reactions to reduce harmful emissions. These metals are rare and valuable, making catalytic converters expensive components of the exhaust system. Their value is mainly due to these metals’ ability to convert toxic gases into innocuous substances, contributing significantly to engine emission control and environmental protection.

• Contain precious metals (platinum, palladium, rhodium)
• Essential for reducing vehicle emissions
• Rare and costly raw materials used inside
• Regulated component to meet emission standards

This intrinsic value also unfortunately makes catalytic converters targets for theft in some regions.

If the catalytic converter warning light appears on your Hyundai Kona dashboard, you should perform the following checks :

• Scan the vehicle’s OBD (On-Board Diagnostics) system for trouble codes
• Inspect lambda sensors before and after the catalytic converter for faults
• Check for signs of catalytic converter poisoning or overheating
• Verify engine ignition system and fuel injection operation

Early diagnosis helps prevent engine going into limp mode and avoid costly repairs. If necessary, consult a professional to confirm if catalytic converter replacement or sensor servicing is required.

Always use unleaded petrol and maintain regular vehicle servicing to prolong catalytic converter life.
