Check it out,
P0442 OBD Trouble Code

Technical Description
Evaporative Emission Control System Leak Detected (small leak)

What does that mean?
This indicates a fuel vapor leak in the EVAP control system. It means a very
small leak has been detected. In fact, the leak can be from a hole as small
as 0.04" in diameter. The (EVAP) emission control system prevents the escape
of fuel vapors from a vehicle's fuel system. Fuel vapors are routed by hoses
to a charcoal canister for storage. Later, when the engine is running a
purge control valve opens allowing intake vacuum to siphon the fuel vapors
into the engine.

Symptoms
You likely won't notice any drivability problems.

Causes
A code P0442 most likely means one or more of the following has happened:

A loose or improperly affixed gas cap
A non-conforming gas cap (i.e. not factory/original brand)
A small leak/hole in a fuel vapor hose/tube
Other small leak in EVAP system
Faulty vent o-ring seal

Possible Solutions
With a P0442, the most common repair is to:

Remove and reinstall the gas cap, clear the codes, and drive for a day and
see if the codes come back.
Otherwise, replace the gas cap, or
Inspect the EVAP system for cuts/holes in tubes/hoses

Re: Engine Code P 0442
 

Thanks folks. I went and re affixed the gas cap and I'll take it out for a
run later, likely tomorrow, and then recheck the codes. When I opened it
up, it made a big old sucking sound. I don't know if this is normal tho
(here in NJ we are not allowed to pump our own gas, thank the gods, the
hazardous material that it is).

The real reason that I will take it for a run later is it is now drying out
from being soaked from today's rainpour. I thought that I could get away
with just the bikini top - LOL on me. Actually, I was fine with my doors
put back on, but that gap between the roll bar and the door was the funnel
point for all of the rain from the top and I ended up with 3 inches of water
on the passenger side when I got home (mostly left turns in the beginning
dumped most of it that way). I was dry tho. Seats all wet, the way back
all soaked from shoving the soaked over-cover in there. I have come to
realize that that over-cover is water resistant, not water proof [grin].
Therefore, I want to let it sit in the sun tomorrow for a bit. ;-]
