PCV Valve Inspection

WARNING: This page is about a different car, the 2011 Honda Pilot, 2010 Honda Pilot, and 2009 Honda Pilot. However, it is still accessible from the selected car via links, so may be relevant.

Remove the engine cover (see step 1 on IGNITION COIL REMOVAL/INSTALLATION ).
Check the PCV valve (A), the hoses (B), and the connections for leaks or restrictions.

At idle, listen to the PCV valve (A) with a stethoscope as you lightly pinch the PCV hose (B) with your fingers or pliers several times. Each time the hose is pinched, the valve should click.
If there is no clicking sound, check the PCV valve grommet for cracks or damage. If the grommet is OK, replace the PCV valve (see PCV VALVE INSPECTION ) then recheck.
