The PCV valve is located behind the alternator, under the intake manifold. The best way I found to get to it is to remove the Passenger front tire, remove the splash guard, Remove the bolts on the Power Steering hose bracket (just makies it easier to get into the area),remove the oil filter. You should be able to see a hose that runs parallel to the engine block behind and above the alternator. I had to grab it with a plier to get enough leverage to pull it out. Once out, I was able to remove the hose and replace the valve. I put a little oil on the valve exterier to make it slide in easier.

I'm Trying To Change The EGR valve ON My 1999 Nissan Quest How Difficult Is It Going To Be, Please Help
On a lot of these vehicles, the PVC valve is located on top of the valve cover, or a hose leading from the valve cover to the intake. You have to remove the right front wheel. It will be in the block. It is in an awkward place and Nissan charges about a 100.00 to install it. You can do it your self though.
It's in the intake one of the bigger hoses that go in. You have to use a wrench to remove it.

The PCV valve is located on the back, drivers side of the intake manifold in a short, rubber hose. It is threaded into the intake manifold close to the last "N" in Nissan which is imprinted into the intake manifold. It requires a 3/4" wrench to remove it.
It is very important to change PCV valve. If valve is old it will plug or seize. This will cause oil pressure to rise and may cause leaks. Most likely the valve cover gaskets will leak if PCV valve is plugged.
That code is for the EGRC-BPT valve. This valve monitors exhaust pressure to activate the diaphram, controlling throttle body vacuum applied to the EGR valvel.
