OBD-II code P0147 indicates a problem with the oxygen sensor circuit for Bank 1, Sensor 3, specifically relating to the voltage signal being out of range or the sensor itself being faulty. This sensor is typically located after the catalytic converter and is responsible for monitoring the efficiency of the catalytic converter. A malfunction can lead to poor fuel economy, increased emissions, and potential damage to the engine. It's advisable to check the wiring and connections, as well as the sensor, to diagnose and resolve the issue.
