Application Guide
Oxygen Sensors Mounting Locations
The illustrations below show several of the most common mounting configurations
for oxygen sensors, depending on engine type and alignment. The terms used for
each sensor location match the terms used in the Application Guide of our catalog.
Check carefully to ensure that you are using the correct sensor for each location.
Please note that the left side is the driver side, the right is the passenger side.
