CAPofMD Posted February 20, 2019 Share Posted February 20, 2019 Got a P0456 code on a CEL that came on last night on my 2015 MKZ Hybrid. Book says "Small evaporative leak". Anyone seen this before? Got a feeling it may be crud on the spring loaded fuel fill port. Haven't tried to clean it yet as weather sucks right now. Any ideas beside what I think ?

Following the instructions to clear the capless fuel system fuel port would be the first step, once the weather clears for you. After that, some other possible causes are: -Evaporative (evap) emission canister or fuel tank leaks. -Evaporative (evap) emission system hose leaking. -Fuel tank leaking. -A small leak in any of the EVAP hoses or fuel tank hoses. -A small leak in the purge valve or vent valve. Hopefully one of our tech members may weigh in and be able to offer more information. Let us know how you make out and good luck. Quote Link to comment Share on other sites More sharing options...
CAPofMD Posted February 21, 2019 Author Share Posted February 21, 2019 (edited) Went out this AM with my code reader and turned off the CEL. Open gas filler door and snapped the nozzle port door a few times. Drove the car to Docs appt and back (about 15 miles total) and no CEL ! Will wait and see ! ... OH! Found out that if a CEL is on you can not use the remote start function ! Edited February 21, 2019 by CAPofMD Quote Link to comment Share on other sites More sharing options...
CAPofMD Posted February 22, 2019 Author Share Posted February 22, 2019 After 2 days the CEL came back...looks like I'll be finding out if my 6 year CPO warranty works. It will have to wait until I get back from vacation away from winter tho. Flying to Yuma, AZ on Tuesday.... 70's - 80's much better than 30's - 50's !!

drolds1 Posted February 22, 2019 Share Posted February 22, 2019 Will that be on the 3:10 to Yuma?? I'll be heading to AZ (Gilbert) in a couple of weeks myself. Enjoy the weather. Quote Link to comment Share on other sites More sharing options...

CAPofMD Posted March 7, 2019 Author Share Posted March 7, 2019 (edited) Anyone know the location of the purge valve on the 2015 Hybrid? Edited March 7, 2019 by CAPofMD Quote Link to comment Share on other sites More sharing options...

CAPofMD Posted March 26, 2019 Author Share Posted March 26, 2019 Found the location and removed it. Couldn't blow thru the valve so put it back on.... code never came back. Canceled the appt with Lincoln dealer. Maybe it was just not tightened enough...whatever no longer a problem. Quote Link to comment Share on other sites More sharing options...
jm98 Posted April 11, 2019 Share Posted April 11, 2019 Its been about 10 years but thinking about driving I8 from Tucson AZ to San Diego CA via Yuma in my MKz Hybrid... I8 is a remote interstate and beautiful desert scenery. Robert Iggy Cerami 1 Quote Link to comment Share on other sites More sharing options...
Mcknlnknmkz Posted April 11, 2021 Share Posted April 11, 2021 I have had the same code on mine several times. On obd-codes.com it does say that this code alone is not to be alarming. I wouldn’t and haven’t conducted a pressure test bc of a very small emissions leak. Because it does keep coming on my Lincoln service shop recommended replacing the gas door first so that’s my current plan. Quote Link to comment Share on other sites More sharing options...
