Code 442 is a small leak in the EVAP system. The computer vents the gas tank to the vapor canister when the engine is running. There is a leak in that venting system.
Sometimes the problem is the gas cap, sometimes it is a hose or valve.
A shop would need to check the gas tank and lines for a leak.

That is an emissions code. It means you have a small leak in one of the lines. Most likely it the line that goes from the engine to the evap canister in the drivers side rear inner fender well.

Need my Liberty to pass smog I recently had codes po445 and po442, will this be a problem for passing smog if check engine light isn't on? Not sure if problem was resolved with new gas cap.


if your check engine light isn't on, they will still hook up a diagnostic code tester to your vehicle to see if the computer has picked up any problems, if the computer has picked up a problem, and you fixed the problem, then you can have the code removed from the system, with a diagnostic code tester.
