Hello & Welcome,

Can you tell us the Year, Model, and Engine you have?
If you have the VIN handy (Vehicle Identification Number), that would be good.

Thanks

Answer

Hi again,

I have a document for you that details what to look for when the code occurs. These are PDF files that you should be able to click on to view on your computer and print.

P0442
Hoses

Once you read through this, you will see that there are some special tools that are required to actually find the leak, but you can do some visual inspection of the parts. Sometimes it is just the gas cap is worn and leaking.

Please let me know if you would like me to send along diagrams of the other parts, as it will require getting all around under the vehicle just to do the inspection.

Thanks, XXXX X.
