P0442 Code
Had to reset a P0442 code today, It has been nagging me for about a month.
I only drive it about 1K a year, so wasn't really an issue , but am selling it so wanted it off.
Will find out if it stays off, but I recall filing it up while it was running a while ago...
Must have been that hopefully, Have a 2 hour drive to my other house where I'm selling it, well see...
Funny the AutoZone guy told me what the code was and but had a smile when he told me so knew it was something stupid...
He said he wasn't allowed to clear it so Amazon shopping I went. Took longer to hook it up and RTFM than to clear them .
