Greetings from Mikey at Just Answer!

The engine oil pressure sensor on a 4.8 Litre is at the top rear of the engine. Here is the component locator graphic.

Still can't see it, what are the steps to remove it. Do you have a step by step instructions?
Expert:  Arench replied 8 years ago.
You have to remove the intake manifold which is not something you want to tackle if you are not experienced with this type of engine.

I would remove the plasic cover or "sight shield" on top of the intake and climb up there, you should be able to see it from above without pulling the intake.
