The Bank 2 Sensor 1 O2 sensor on a Dodge Durango is typically located on the exhaust system, specifically on the driver's side, after the catalytic converter. It monitors the exhaust gases coming from the engine to help manage fuel efficiency and emissions. Depending on the engine configuration, it may be positioned near the rear of the engine or closer to the transmission. Always refer to the specific service manual for the exact location based on the model year and engine type.
