Operation and Emissions Compliance
The Walker CalCat Carb 83692 catalytic converter functions by converting harmful pollutants in the exhaust gas into less toxic substances. It utilizes an optimal high-technology washcoat formulated to deliver superior performance in emissions reduction.
- CARB Compliant: This converter is designed to meet the stringent emissions standards set by the California Air Resources Board (CARB). It is legal for sale and use in California, Colorado, New York, and other states requiring CARB-compliant replacement converters.
- EPA Compliant: It is also EPA compliant for OBDII vehicles, ensuring it meets federal emissions requirements.
- Check Engine Light: The advanced design and precise OE-style coating process help prevent the illumination of the "Check Engine Light" due to emissions-related codes, ensuring consistent performance and compliance.

Maintenance
The Walker CalCat Carb 83692 catalytic converter is designed to be a maintenance-free component of your vehicle's exhaust system. Its robust construction and advanced internal components are built for long-term durability and performance without requiring regular servicing.
To ensure the longevity and optimal performance of your catalytic converter, it is recommended to:
- Adhere to your vehicle manufacturer's recommended maintenance schedule for engine tune-ups and fuel system checks.
- Address any engine performance issues (e.g., misfires, excessive oil consumption) promptly, as these can negatively impact the converter's efficiency and lifespan.
- Avoid using leaded fuels, as lead can contaminate and damage the catalytic converter.
Troubleshooting
While the Walker CalCat Carb 83692 is designed for reliable performance, certain issues may arise that could be related to the exhaust system or emissions control.
Common Issues and Potential Causes:
- Check Engine Light (CEL) Illumination:
- While the converter is designed to prevent CELs for emissions, other vehicle issues (e.g., oxygen sensor malfunction, engine misfire, fuel system problems) can trigger it.
- A diagnostic scan tool can retrieve trouble codes to identify the specific cause.
- Failed Emissions Test:
- If the vehicle fails an emissions test, it could indicate an issue with the catalytic converter or other components of the emissions system.
- Factors like engine condition, oxygen sensor performance, and exhaust leaks can affect emissions.
- Reduced Engine Performance or Unusual Exhaust Noise:
- A severely clogged or damaged catalytic converter can restrict exhaust flow, leading to reduced engine power.
- Rattling noises from the exhaust system might indicate internal damage to the converter's substrate.
Recommended Action:
If you experience any of these issues, it is highly recommended to have your vehicle inspected by a certified automotive technician. They can perform a thorough diagnosis to accurately identify the problem and recommend appropriate repairs.
