P0442 TROUBLE CODE

[CHARLIE CARDONE]

Has anyone had to fix this trouble code? There are some post about it but not how they actually fixed it. It's in th EVAP control system somewhere. Any thoughts?

Thanks

P0442 Evaporative Emission Control System Leak Detected



Most of the time this it is a gas cap related issue... Remove the gas cap, clean the gasket and re tighten. It will take a couple of days to go off... OR you can disconnect the battery to reset the computer...

Hey Todd Z,



I did a rear shock replacement last week, I dropped the breather box for an easier install.

I'm not sure but If I didn't hook up all the hoses I disconnected to the breather box would that give me a P0442 code? Just wondering

Thanks

I would be willing to bet you have diagnosed the problem yourself.

Thanks Tom,



I wasn't sure because the check engine light didn't come on until 2 days after the shock install.

charlie, that's probably the problem. The computer has to run a test for the CEL to come on. The CPU doesn't always run tests of the system. It does it at cirtain intervals. May have been that long before it ran and recognized the issue.

Same thing happened to me and I knew right away what it was. One of the hoses was not pushed on tight enough and it came loose. CEL turned two days later. Pushed hose on until I heard and felt the connector snap into place. Two days later CEL turns off.

any time.

You can put a zip tie on the hoses to help hold them on..
