Lincoln Evaporate Emission Issue
Some 2013-2014 Lincoln MKZ vehicles built on or before July 14, 2014, might exhibit an illuminated MIL with DTC P0456. P0457, P04EE and/or P04EF. Reprogram the PCM to the latest calibration using IDS release 92.03 or higher. Make sure you are connected to the Internet when entering module programming to obtain the latest updates. Also, replace the evaporative emission canister purge valve. Refer to workshop manual 303-13.
