Bought my car used in AZ, moved to CA. Car doesn't pass emmissions test. There was a recall related to this issue but it's now closed. How do I know if my car was affected by this recall?

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! It sounds like your Mazda 3 is in the midst of a classic "emissions test drama," with a subplot involving a recalled part. If your car isn't passing the emissions test and there was a recall related to this, it's worth checking if your vehicle was affected. Start by contacting Mazda’s customer service or checking their recall database online. You’ll need your VIN (Vehicle Identification Number) to see if your car was part of the recall and whether it was addressed. Even though the recall might be closed, they might still offer solutions for unresolved issues. Given the CEL (Check Engine Light) has been on since the TCM replacement, it's possible that a software update is needed to align everything with the emissions system. Visiting a Mazda dealership for a diagnostic and software update would be a good step. They can also check if any issues from the recall might still be affecting your vehicle.
