Service bulletin 02-170-17R

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's 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.
