2000 Jeep Cherokee Sport 4.0L Misfire, MIL Lamp on
Posted to Chrysler Driveability on 5/4/2010 8 Replies

Modis troubleshooter and Alldata do not list the P1685 code. Does anyone have any idea what that means or what may be causing it? Two members have that listed in the knowledge database, but neither show a fix for it. Thanks for any and all help!
