it is located on the engine (passenger side) right next to the idle control valve it is a pain in the but to get there and even worse to take it out, and it is connected to a little hose that comes from the engine, but to get acces to it you need to take de idle valve out first, otherwise you will not be able to the pcv plus that you might want to take the oil filter as well that way you'll have more room to work,i spent a lot of time trying to fins it on my car and i didn't find any answer it took me a while to get it out good luck...

Contacted the dealer and the 02 does not have an egr valve The original question was "where is the PCV valve located? An EGR stands for "exhaust gas recirculation" which is different from a PCV valve "positive crank case ventilation". Each serves a unique and different function within the engine. Therefore the original question remains unanswered! daaaaa... The PCV valve is located on the back side of the valve cover. You will see the hose that the valve is connected to, running out from the back of the valve cover. The actual PCV valve is screwed into the valve cover, and the hose will have to be disconnected to access the valve.
