Hello,
I’ve been dealing with a P0442 for a while now. My Expedition has a 3.5 Ecoboost with the capless gas filler.
I tried to clean the gas filler and replaced both the purge valve and vent valve with no luck. Now in addition to the P0442 it’s showing a P1450.
Has anyone dealt with this before or have any recommendations? I have a smoke machine coming from Amazon this week and plan on doing a smoke test as my next step.
Any help would be greatly appreciated.
