5. Operating Principles and Emissions Compliance

The Walker Ultra 16491 Catalytic Converter is a critical component of your vehicle's emission control system. It converts harmful pollutants in the exhaust gases into less toxic substances through chemical reactions.

5.1 Emissions Reduction Technology

This converter utilizes an OE-style high-technology washcoat and an optimal precious metal load to achieve the required reduction in tailpipe emissions. This precision engineering ensures your vehicle meets environmental standards.

5.2 Konfòmite Regilasyon

• Konfòm ak EPA: This converter is compliant for use on OBDII vehicles manufactured in 1996 and newer. It meets federal Environmental Protection Agency standards for emissions.
• CARB Compliant: For states requiring California Air Resources Board (CARB) compliant replacement converters (e.g., California, Colorado, New York), please ensure you purchase the specific CARB-compliant model if required for your region and vehicle year. This specific model (16491) is EPA compliant.

6. Antretyen

Catalytic converters are generally maintenance-free components. However, their longevity and efficiency are directly linked to the overall health of your vehicle's engine and exhaust system.

• Antretyen motè regilye: Ensure your engine is properly tuned, and perform regular oil changes and spark plug replacements as recommended by your vehicle manufacturer. A well-maintained engine prevents unburnt fuel from reaching and damaging the converter.
• Repare pwoblèm motè yo rapidman: Any issues causing misfires, excessive oil consumption, or rich fuel mixtures can severely damage the catalytic converter. Address check engine light warnings immediately.
• Enspekte sistèm echapman an: Periodically check the entire exhaust system for leaks, corrosion, or damage that could affect the converter's performance.

NAN. Depanaj

If you experience issues after installing your new catalytic converter, consider the following common problems and solutions:

7.1 Check Engine Light (CEL) Illumination

• Kòz: Often triggered by an oxygen sensor reading outside normal parameters, or a persistent engine issue.
• Solisyon:
  1. Ensure O2 sensors are correctly installed and functioning.
  2. Scan the vehicle's onboard diagnostics (OBD-II) system for specific trouble codes.
  3. Address any underlying engine problems (e.g., misfires, fuel system issues) that could be causing the CEL. A new converter will not fix pre-existing engine problems.

Figure 6: The check engine light indicates a potential issue with the vehicle's emissions system or engine.

7.2 Exhaust Leaks

• Kòz: Improperly seated gaskets, loose bolts, or damaged flanges.
• Solisyon: Re-check all connections, ensure gaskets are correctly installed, and tighten bolts to specification.

7.3 Rattling Noise

• Kòz: Can indicate a loose heat shield or internal damage to the converter's ceramic substrate.
• Solisyon: Inspect heat shields for proper attachment. If the noise persists and is internal to the converter, it may require replacement.
