Jeep Liberty Diesel codes P1401 and P1140
Did "blowing your nose" with the overdrive off fix a current fault code or is this suggested by some for maintenance with a properly functioning valve?
Does anyone have any pics of the service or a recommended source for a service manual? I'm mechanically inclined so I'd love to do this repair myself if possible.
If disconnecting is the real answer, again, back to the pics question to illustrate. Where is the dern thing located?
Thanks very much for any feedback. I belong to another auto forum and I appreciate peoples willingness to share and help. Much thanks ahead of time.
