Hi All
Its been a little while. My 11 non-PP SHO surprised me the other day by throwing a temper tantrum of sorts by giving me the P0442 code. I guess it wanted some attention.
It comes up as a small EVAP Canister Leak. In researching this, it doesn't look like any other issues are present (smooth idle, runs normal). You wouldn't know it has an issue unless you saw the CEL. According to the "all-knowing" interwebs, this can be caused by the gas "cap" flapper thingy so I gave that a good cleaning (like Ford TechMakuloco shows), cleared the code, and the code has returned after about a week of driving.
From what I have seen, the next likely culprit is EVAP canister valve solenoid. This is where it gets complicated. Again, according to the "all-knowing interwebs", there are conflicting part numbers.
Does anyone have the correct part number for the EVAP valve solenoid or have any experience on this particular issue.
