mike33 Posted April 8, 2015 Report Share Posted April 8, 2015 Hi Guys, haven't posted in a while. Hope everybody is doing well. My 2008 DTS just started throwing these codes. Any suggestions on where to start with a repair? Thanks! Mike Quote Link to comment Share on other sites More sharing options...

barczy01 Posted April 8, 2015 Report Share Posted April 8, 2015 Check for a bad vent solenoid. Check for a 10 amp fuse in the trunk that might be blown. Sorry I'm unsure what its labeled. Quote Link to comment Share on other sites More sharing options...
mike33 Posted April 14, 2015 Author Report Share Posted April 14, 2015 ok, thanks. Do you have any pictures or more specific locations, so I can find these things? Thanks! Quote Link to comment Share on other sites More sharing options...
Logan Posted April 15, 2015 Report Share Posted April 15, 2015 The EVAP solenoid is going to be part of the canister....under the car...about where the rear drivers side seat butt position would be....the fuse block will be under the rear seat cushion.

mike33 Posted April 25, 2015 Author Report Share Posted April 25, 2015 Team, thanks for your help on this. I replaced the vent solenoid, and no check engine light for a week now. Quite a few ignition cycles. I used BWD part# CPV48 from O'reily. Hope this info helps someone again sometime. Best Wishes, Mike Texas Jim 1 Quote Link to comment Share on other sites More sharing options...
