NOTE: The illustration shows 2000-2003 models.
At idle, make sure there is a clicking sound from the PCV valve when the hose between the PCV valve and intake manifold is lightly pinched (A) with your fingers or pliers.
If there is no clicking sound, check the PCV valve grommet for cracks or damage. If the grommet is OK, replace the PCV valve (2005 model) (see PCV VALVE REPLACEMENT ) and recheck.
