  O2 Sensor Identification Guide

  AnOBD Scan Toolwill usually identify Oxygen Sensors by theBank Number(B1 = Bank 1) andSensor Number(S1 = Sensor 1). Bank 1 will always contain Cylinder 1, which is located closest to the front of the engine.

  Part manufacturers often use different terms than scan tools to identify sensor positions. Regardless of the vehicle's engine orientation, the right or left bank is determined by viewing the engine from the rear (opposite the drive belts).
