Where is the P0420 OBD2 trouble code stored?

The front O2 sensor measures the mixture, and it tells the engine control unit if the engine is running with a rich or lean mixture and adjusts it. The rear O2 sensor is just a diagnostic O2 sensor for this trouble code. If the rear O2 sensor is getting faulty values, the p0420 code will get stored in the engine control unit.
