Discover the Power Bank 2 Sensor 1 and Its Impact on Engine Dynamics

Bank 1 is the side with the #1 cylinder (Cylinders 1 – 3 – 5 – 7 etc) Bank 2 is the side with the #2 cylinder (Cylinders 2 – 4 – 6 – 8 etc) Oxygen Bank 2 Sensor 1 replacement · Unplug the old sensor · Unscrew the old sensor · Apply a small amount of anti-seize to threads of new ... First, find the connector, squeeze it and disconnect it. Then, use the Oxygen Sensor Removal tool and engage the sensor from under the car. The driver side bank reads way differently than the passenger side, and the verdict that it's Bank 1 that's the anomaly is, fuel table values match the sensor ... In all cars, Bank 1 is the side closest to cylinder 1 (which on the VR6 is passenger side for LHD cars). Sensor 1 is always upstream of the cat. Our cars don't have 'bank one' or 'bank two'. We have upstream and downstream. They are different sensors. The upstream one is the important one. The O2 sensors are located on the exhaust system (easy to spot as they stick out). You can get them from most any auto parts store. Bank 1 Sensor 2 is the passenger side downstream (post-cat sensor). A Bosch downstream sensor is $53 and replacing it shouldn't take a ... Where is the bank 2 oxygen sensor 1 located? I know it is a downstream sensor and I located both directly after the cat, but I dont know which one it is. The o2 sensor of bank2 is stuck at 1.27 volt in first start when engine is cold and it is starting to drop after engine is fully warmed.
