Code P0160 Infiniti Description

The P0160 Infiniti code indicates that there is no activity detected in the O2 sensor circuit of Bank 2 Sensor 2. This sensor is responsible for monitoring the oxygen levels in the exhaust gases after they have passed through the catalytic converter. The data collected by this sensor is crucial for the engine control module (ECM) to adjust the air-fuel mixture for optimal performance and emissions control. When no activity is detected in this sensor circuit, it means that the sensor is not sending any signals to the ECM, which can lead to various issues with the vehicle's performance.
