Navigating the regulations for aftermarket catalytic converters can be complex, especially when ensuring your vehicle is OBD2 compliant. The California Air Resources Board (CARB) has taken a significant step to simplify this process by developing a comprehensive database. This resource is designed to help you determine which aftermarket catalytic converters are approved for use in California, specifically for OBD II vehicles and beyond.
This database is an invaluable tool for vehicle owners, auto repair professionals, and parts distributors who need to verify compliance with California’s stringent emissions standards. Initially focused on aftermarket catalytic converters approved for OBD II vehicles under regulations effective January 1, 2009, the database is continuously expanding. The ultimate goal is to include listings for non-OBD II vehicles as well, making it a truly comprehensive resource.
While the database is searchable online, you may also be looking for a downloadable Obd2 Compliant Vehicles List Pdf for offline access or easier sharing. CARB provides several resources that function as lists, although they may not be in a single, directly labeled “OBD2 compliant vehicles list PDF” format.
Here’s how to effectively utilize the resources provided by CARB to find the information you need regarding OBD2 compliance and aftermarket catalytic converters:
-
Aftermarket Catalytic Converter Database: Aftermarket Catalytic Converter Database – This is your primary online resource. You can search by vehicle information or ARB Executive Order number to check specific catalytic converter approvals.
-
Executive Orders (EOs) for Approved Catalytic Converters: The database references Executive Orders, which are official approvals from CARB. For a complete listing of approved catalytic converters under the new regulations, you can view the comprehensive list in PDF format here: Complete List of Approved Catalytic Converters. While not explicitly titled “OBD2 compliant vehicles list PDF,” this document contains extensive information and can be considered your master list.
-
Pre-OBD II Vehicle List: If you are working with older vehicles, CARB also provides a specific listing for pre-OBD II vehicles: Pre-OBD II EO Listing. This is a separate resource from the OBD II database and list.
Important Alerts and Notes:
-
Rescinded Executive Orders: Always be aware of Executive Orders that have been rescinded or withdrawn. Catalytic converters under these EOs are no longer legal for installation or sale in California. Review the list of rescinded EOs here: Rescinded Executive Orders.
-
Toyota Specific Alert: For owners of 2001-2004 4.7 liter Toyota Sequoia and 2003-2004 4.7 liter Toyota Tundra models, there is a specific alert regarding legal catalytic converters. Refer to this document for approved options: Toyota Sequoia and Tundra Catalytic Converter Alert.
-
Compatibility View for Internet Explorer Users: If you are using Internet Explorer and encounter display issues with the database, CARB recommends checking the Compatibility View settings as outlined here: IE Compatibility View Instructions.
-
Medium and Heavy-Duty Vehicles & Motorcycles: The database and linked lists are specifically for passenger cars, light-duty trucks, and medium-duty vehicles only. For motorcycle aftermarket catalytic converters, please refer to the Motorcycle Aftermarket Parts Page.
By utilizing these CARB resources, particularly the comprehensive PDF list of approved catalytic converters and the online database, you can effectively find the information needed to ensure OBD2 compliance for aftermarket catalytic converter installations in California.
