I've got the same question. Rather than a new post, I found this thread. Our car is also the 2002 model. Is there a diagram somewhere showing the location of various parts?

I did that search before posting yesterday, and none of the results were useful. Some even say that the 2002 engine has no PCV valve, just the oil-air separator.

I don't know why I'm getting sucked back in.....

The code you are getting is from a breather that can clog. If memory serves....and it has been years since I turned a wrench on an M111, you will see a brass looking canister the size of a small childs fist at the rear of the engine above the transmission tunnel. It gets clogged and the lack of vacuum causes the trouble code.

Feel free to critique my input, but this is how I recall clearing that trouble code after many resets.

I don't remember the code exactly, but on my scan reader it would come up as PCV Valve.
