Do you have a photograph showing the location of pcv valve for this vehicle?
Locationof pcv valve on 2003 Honda Civic Hybrid
The PCV valve is threaded in to the intake manifold. it is goldish in color with the PCV hose coming out of it. Look at your under hood emissions label with the vacuum diagram and find the vacuum line that goes to the PCV system( it should be labeled as such ) and trace that to the valve. Good Luck!
