A code P0420 on a 2006 Honda Pilot indicates that the vehicle's onboard diagnostics have detected an issue with the catalytic converter's efficiency. This code typically means that the converter is not functioning as effectively as it should, which can be caused by a faulty catalytic converter, oxygen sensors, or exhaust leaks. It's important to diagnose the specific cause to ensure proper repairs, as ignoring this code can lead to increased emissions and potential damage to the engine.
