I just went to autozone and bought both replacement oxygen sensors. I'm trying to save money by replacing them myself, but have no idea how to do it or where they are located.
HelloCustomerand Thank you for choosing Just Answer.
There are 4 oxygen sensors ion your 4.0L There are two upstream sensors and two down stream sensors. If you look in the engine compartment at the exhaust manifolds, Right after the manifolds end and the downpipes start, You will see the oxygen sensors. These are the two upstream, One on each side. Then after the catalytic convertors on each side you will see both the down stream sensors. The sensors ahve either a blue or green connector.

Is there any way that I could get a diagram of all this?
This picture describes the two upstream sensors. To replace the downstream you will need to get under the truck.
