Land Rover Discovery check engine light issue with P0062 code related to rear oxygen sensor replacement on Land Rover Discovery

Some Land Rover Discovery owners report experiencing issues related to the P0062 trouble code, which indicates a problem with the heater element circuit of the rear oxygen sensor. This code can be triggered by water entering the heated oxygen sensor connector, potentially leading to a blown fuse. Owners may need to locate and replace the rear oxygen sensor, specifically sensor 3 on bank 2, which monitors exhaust gases post-catalytic converter. If the P0062 code remains after attempts to clear it, further troubleshooting may be necessary to identify additional underlying issues with the oxygen sensor or its components. It is advisable for owners to address the root cause of this trouble code promptly to avoid further complications.
