The PCV valve is located in the valve cover on the passenger side of the vehicle. The valve is closer to the firewall than it is to the front of the engine. It has a hose attached to it and threads into the valve cover.

Here's a screenshot from the field service manual of a 2005 Pathfinder. It shows the rocker cover on the top of the driver and passenger side of the engine. The PCV valve is connected into the back of the passenger side rocker cover. One of the PCV hoses comes out of it, up and back into the intake manifold. Hope it helps..

Where is the pcv valve located on a 2003 hyundai sonata


I have a 2003 Hyundai Sonata GLS 2.7L V6 , I'm having a problem locating the pcv valve. I was told it was on the valve cover near the fire wall. Is it located near the throttle body? i have to take off the intake to change the plugs so I'm sure I will find it then. Just thought I would ask someone that has pervious experience. Thanks for anyone's input.

PCV VALVE REPLACEMENT


The pcv valve is usually located on one of the valve covers look for the larger vacuum hose coming from the intake manifold and follow it you should find it that way. changing it is a matter of sometimes using a pair of pliers to remove a small clamp then rotate back and forth the pcv valve while holding the hose and pulling it away and off.
