2006 Honda Pilot EX, 3.5 YF2, J35Z1SECTION PCV Valve Inspection and Test
- Remove intake manifold cover (see step 1 IGNITION COIL REMOVAL/INSTALLATION ).
- Check the PCV valve (A), hoses (B), and 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 and recheck.
