My 2006 Liberty CRD gave me a code P1140
It runs fine but I have noticed 2 problems
First thing is temp gauge now runs dead in middle as straight up but normally it would be below that mark even in summer.
Second thing I noticed now is she starts good cold but when warm takes few extra revolutions before firing up
Any thoughts.

P1140 EGR Throttle Control Circuit Open
Possible Causes
EGR Airflow control valve connector is damaged (check pins for damage)
EGR Airflow control valve control circuit is open or shorted to ground
EGR Airflow control valve supply circuit is open (check power from ASD relay)
EGR Airflow control valve has failed
