SOURCE: 2 po442 codes showing up on my 2003 buick century

If there was a leak at the gas cap. EG: Left off or loose after fill up? You will need to have the codes cleared or it will clear itself after enough key cycles. EG: Started and shut back off as many as 20 to 50 or more times.

Usually the source of the leak is the gas cap (either loose or defective) but if that doesn't apply to your issue then the canister is next to the gas tank.

SOURCE: AN AUTO TECH USING A DIAGNOSTIC MACHINE GOT A CODE

This DTC (P0442) depends on what caused the code to set. Most times it's simply a loose fuel cap or the O-ring on the fuel cap is damaged OR dirt got between the O-ring and the mating surface of the fuel filler tube. There are numerous possible causes for the DTC you have -- Fuel cap, pin hole in fuel system (evap hoses, fuel tank, fuel cap), canister close valve leaking, fuel tank pressure sensor malfunction, purge control solenoid valve malfunction, etc.
BEST SOLUTION: Take the vehicle into a Hyundai Service Center (dealership), pay the diagnostic fee. They will tell you EXACTLY what the problem is and what's needed to fix it (parts, labor, tax, time-frame, etc.). If you perfer to try and fix it yourself, Go to http://www.hmaservice.com/ and register (vehicle by VIN). Afterward, you'll have access to technical information (manuals, wiring diagrams, service bulletins, etc) about your vehicle.

SOURCE: Evap leak

your caravan has a system to control fumes from the gas tank .. any evaporating fuel is absorbed into a canister .. that is connected to a evap/purge solenoid in the engine compartment that directs the fumes to be burned in the engine once its running .. .. the problem can be as simple as a damaged or leaking or wrong type gas cap .. if the gas cap doesnt seal well then air can be drawn into the evaporitive control system ... also if any of the hoses from the evap/purge solenoid to the canister (located near the gas tank) are cracked or loose, you will get the same results .. some of these hoses are rubber .. some are hard plastic .. sometimes they come loose at the canister and need a clamp added ... the evap/purge solenoid could also be bad but much more likely the gas cap is just bad, bent or wrong ..

SOURCE: Evap Emissions Leak

This can be because the Gas cap is not holding the pressure. I would start there first.

Code p0442


2005 Galant with code po442 this code is for an evap leak, a small leak, check the gas cap for any cracks in the oring and then you will need to check the evap lines, these line sometimes crack and allow vacuum to leak, this system is computer controlled to allow venting or purging.
most of the time a small evap leak may be due to a bad gas cap but other times it could be a line or rusted filler neck or other problems. the best way to find such a leak would be with an evap smoke machine, thee machine pumps smoke into fuel tank and lines for evap system and with vent valve shut the system should be air tight, then you look for smoke and where smoke is that is your leak, most repair shops have the machine, note : some leaks are so small the smoke can not be seen ,at this point soap water in a spray bottle is helpful, spray lines and other areas to see bubbles.

Never heard of the EVAP System?

It allow you to fill your fuel tank and under

Same as any other Malfunction Indicator

find solution and repair.

The leak could be a hose,valve,solenoid
or one of 15 items in the system

Engine coad po442 how do i fix it


PO442 is the data trouble code for (evaporative emission control system leak detected "small leak") it means that the OBD-II system has detected a small vacuum leak in the evaporative control system.

You will need to find the vacuum leak in the evaporative control system, check for cracked or broken vacuum lines and hoses, especially the vacuum hoses and lines around the evaporative (Evap) canister and the (Evap) solenoid. Also check the gas cap seal for damage.

Vacuum hoses and lines should be checked very well for any cracks or breaks, because they usually hide under the vacuum line or hose.
