Code P2415 Description

The diagnostic trouble code P2415 refers to an O2 sensor exhaust sample error for Bank 2 Sensor 1. In modern vehicles, the oxygen sensor (O2 sensor) plays a crucial role in monitoring the oxygen content in the exhaust gases. The O2 sensor measures the amount of oxygen in the exhaust stream and provides feedback to the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion. Bank 2 refers to the bank of cylinders that does not contain cylinder 1, and Sensor 1 indicates the sensor located before the catalytic converter in that bank.
