Some 2013-2017 C-Max/Fusion/MKZ Hybrid/Energi vehicles may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble codes (DTCs) P1450, P0456, P0457, P04EE and/or P04EF. This may be due to the sealing capability of the canister purge valve. To correct the condition, follow the Service Procedure steps to update the PCM software and replace the canister purge valve.
