Code P0153 2003 Infiniti G35 Description

The P0153 code on a 2003 Infiniti G35 indicates an issue with the O2 sensor circuit for Bank 2 Sensor 1. The O2 sensor, also known as the oxygen sensor, plays a crucial role in monitoring the oxygen levels in the exhaust gases and providing feedback to the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion. In this case, the code specifically points to a slow response from the O2 sensor in Bank 2 Sensor 1, which is typically the sensor located before the catalytic converter in the exhaust system of the vehicle.
