Code P014C 2011 Nissan Rogue Description

The diagnostic trouble code P014C for a 2011 Nissan Rogue indicates that there is a slow response from the air-fuel ratio sensor located in Bank 1 Sensor 1. This sensor is responsible for measuring the oxygen content in the exhaust gas and sending this information to the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion. A slow response from the sensor can lead to the engine running too rich (too much fuel) or too lean (too little fuel), affecting performance, fuel efficiency, and emissions.
