Maintenance/Repairs

Our check engine light is on permanently in our 2000 toyota tacoma. This car was purchased in California and has the CA smog equipmtn, but we now live in Oregon.

Diagnostics have been run multiple times. The code it gives is for the catalytic converter. We?ve replaced the catalytic converter twice and had the mass airflow repaired. The check engine light always comes back on. We?re wondering if this is possibly due to the fact that the truck is set up for California smog and the cats have all been replaced in Oregon. After we put the 2nd cat in the light stayed off for the first 250 miles, but then came right back on. We had the diagnostic run again and it still came up with the cat error.

We?re not sure if the California cat is different than the ones we?ve had installed in Oregon or, if the computer needs to be reset differently because of California?s smog standards.

Thanks
