    I've had a Bank 1 O2 sensor code (0420) since purchasing my car used in 2010. The check engine light came on within the first week of owning it. It has been an ongoing issue every year trying to get it inspected. I'm told it's more that the converter is shot. It would be great to find out if my car fits said recall. Especially since replacing the converter would be ridiculously expensive for me!
