Needs to be in the PUSHROD section.

Crank position sensor is located on the rear of the engine (the side facing the firewall). It is a PITA to do. There is also the risk that when you try to remove it, it will break off, and have a big hassel to get it out.

I will try to get a pic of where it is for you when I get my scanner reloaded.

Ugh. I just went though that with my 2.8. When you try to pull it out, I'd suggest spin it and spin it some more as you pull on it. I went with a screwdriver to try and pry it out and broke it up. Ended up having to drop the oil pan to push it out.

The problem is the end swells up a bit and the usual crud on it prevents it from coming out. Try to spin it to wear all the crud off, otherwise there's a good chance you'll need to drop the pan.

I thought I had a better pic, but this one will have to do for now.

This is the BACK of the engine. This is actually on a 3.4 DOHC (that is why the alternator is on the back), but the Crank Position Sensor is located in the same spot on the 2 engines.
