code p0420 ?
i just failed my emission test. it said fault code p0420: catalyst system efficiency below threshold (bank 14). what is that mean? is it the cat or the o2 sensor?

could also be a memory code, meaning it failed recently but the ECU hasnt checked the sensor again. it makes a note about the failure then check later.
