Oxygen 02 sensor

Hello,

This depends on what engine you have and which sensor you need.

You noted that this was a v8 so I will assume that you have a 5.4L.

There are three oxygen sensors on this vehicle, located on the exhaust system. I've attached diagrams showing their location and also a step-by-step guide for replacing the oxygen sensors.

However, I will also attach the info for the other engines as well so please note which one you are looking at by the engine callout on each page.

These repair guides help explain how oxygen sensors work, and provide an overview of what to expect when replacing them:
