PICTORIALS OF THE DESIGNATION OF OXYGEN SENSORS






There has been some confusion relative to OBD II oxygen sensor designation. The intent of this article is to eliminate misdiagnosis of those oxygen sensors due to misidentification. This chart can help locate the appropriate bank and sensor for the diagnostic.

NOTE: For "V" engines; BANK 1 is always on the side of the engine with the number 1 cylinder (odd cylinders), and BANK 2 is always on the side of the engine where the number 2 cylinder (even cylinders) is located.
