A vacuum leak from the PCV grommet vacuum leak can cause the Check Engine Light to illuminate. The molded rubber hose connections may crack and collapse, causing the vehicle to run roughly. A damaged PCV hose will require replacement.

    Small hose between PCV valve and larger intake vacuum hose collapsed. Note PCV valve was not changed at 100000 miles as per the manufactures required maintenance.

    Changed PCV and vacuum elbow from engine to pcv valve. Also cleaned the mass air flow sensor with carb cleaner and disconnected the battery for 30 minutes to clear the computer. It was a 30 minute job and fixed the service engine light.
