Dreaded P0442, P0455 on '02 TJ Sport
Okay, so warranty expired a few months back
and now I start getting the dreaded P0442 and
P0455 MIL errors (small and large leaks in the
evap emissions system). I have reset the
computer several times and they keep coming
back - no other errors though.
So I want to start by replacing the gas cap as
some have suggested elsewhere. Local dealership
(the only one for 150 miles in any direction) wants
$20 and they would have to order it! Is there
anywhere online I can get a factory gas cap for
a reasonable price?
What other things should I be checking related
to these codes?
Any ideas greatly appreciated . . . JELo

When I had those same codes last Fall, I traced all the evap lines from
the tank to the canister and found a short piece of hose had split
right at the purge solenoid. Replacing it cleared my codes shortly
after for only $2.

Good question, hadn't thought of that.
I have heard there are differences, I'll
have to see what I can find. Thanks, JELo
