On a 2007 Cadillac Escalade ESV, Bank 1 Sensor 2 is located on the exhaust system, specifically after the catalytic converter on the driver's side of the vehicle. This sensor is part of the oxygen sensor system and monitors the efficiency of the catalytic converter. To access it, you may need to lift the vehicle and possibly remove some protective covers or components. Always ensure the vehicle is safely secured before attempting any maintenance.

In a 2002 Cadillac DeVille, the Bank 1 Sensor 1, which is the upstream oxygen sensor, is located on the driver's side of the engine. It is positioned in the exhaust manifold, before the catalytic converter. This sensor monitors the oxygen levels in the exhaust gases to help the engine control module optimize fuel injection and emissions.
Bank 1 (cyl. 1-3-5 passenger side) Sensor 1 (first sensor from engine) is accessible from under car. It is located just before the catalytic converter.
Facing the car it is on the passenger side under the car after the cataylic converter
Bank 1 refers to the side of the car with the number 1 cylinder, on your vehicle it is the rear side of the engine. Sensor 2 is the second sensor, the one after the catalytic convertor, in the exhaust pipe coming from the engine.
In a 2007 Cadillac CTS 2.8L, bank 1 refers to the side of the engine that contains cylinder 1. For this engine configuration, bank 1 is on the driver's side. This is important for tasks such as diagnosing issues or replacing components like ignition coils or oxygen sensors.
