1995 Toyota pickup with aftermarket catalytic converter.

I have a 1995 Toyota Pickup. My truck passed the smog test except the CARB (Executive Order) numbers on the catalyic converter were unreadable. I tried to make them show up and nothing works. Is this really a law? Does the smog technician need to see the EO numbers before passing my Toyota pickup? And if so what can I do about it without spending more money?
Answer:

CATs which are sold legally in California must possess an EO number, (EO stands for Executive Order). This is the number given to the product by the California Air Resources Board certifying that it is emissions legal. Without a eligible EO/CARB number a smog check technician can not verify the catalytic converter is California legal and must fail the vehicle. Most manufactures of aftermarket exhaust or emission components will stamp this number on the actual unit or they will print in the units manual, catalog or some other paperwork which pertains directly to the component in question. You will have to present this number to the smog station where the car is being tested. Local auto parts stores are required by law to sell only California legal CATs. If you can show documentation to the smog technician indicating the EO number the technician should be able to pass your 1995 Toyota Pickup truck. posted by SmogTips Support
