Hello and welcome to justanswer.com
That code P0420 is usually a problem with the converter which may need to be replaced. Bank 1 is the passenger side. We should make sure the sensor connectors are clean and secure and we can try clearing the code and disconnect the negative battery terminal cable for 10 minutes to see if the code returns.

what about stability control fail code and the ABS light being on ?which has been on since I owned the car.
Expert:  Richard replied 1 year ago.
That is unrelated. Could be a bad wheel speed sensor or control module. There will be separate faults stored in the ABS module which will need to be read.
