- Summary
- This bulletin announces part information for new Active Valve Control System (AVCS) oil control solenoid valves (OCV) which contain a redesigned internal oil seal. The new seal will eliminate potential oil seepage into the wire harness connector portion of the valve. If oil seeps into the connector, over time, the Check Engine lamp may illuminate and set various AVCS-related DTCs.
