Code P0420 on a Nissan Armada indicates a problem with the catalytic converter's efficiency. To fix it, start by inspecting the exhaust system for leaks, ensuring that all connections are secure. Next, check the oxygen sensors for proper operation, as faulty sensors can trigger this code. If both the exhaust and sensors are in good condition, the catalytic converter may need to be replaced.
