Code P2272 2017 Chevrolet Silverado Description

The P2272 diagnostic trouble code (DTC) for a 2017 Chevrolet Silverado indicates that the oxygen sensor (O2) signal for Bank 2 Sensor 2 is stuck lean. This means that the O2 sensor located after the catalytic converter on the side of the engine that houses cylinder number 2 is consistently reading a lean air-fuel mixture. The O2 sensor is responsible for monitoring the amount of oxygen in the exhaust gases and sending this data to the engine control module (ECM) for proper fuel delivery. When the O2 sensor signal is stuck lean, it can lead to a variety of performance issues in the vehicle.
