If you see a P0442 DTC, you know there is a fuel vapor leak somewhere in the EVAP system. The small leak code tells you that the leak is probably minor. If your OBD-II diagnostic scanner registers a P0442 DTC, you must find and repair an EVAP system leak.

How to repair a p0442 EVAP system leak?
With a P0442, the most common DIY repair is to: 1 Remove and reinstall the gas cap, clear the codes, and drive for a day and see if the codes come back. 2 Otherwise, replace the gas cap (we recommend an OEM original part, not aftermarket part), or 3 Visually inspect the EVAP system for cuts/holes in tubes/hoses
Why is my EVAP code not coming back?
Once you do, clear the code on the OBD-II scanner and drive for a few days. If the code does not return, your gas cap probably was the culprit. Of course, there is a chance your gas cap either has worn out or is not compatible with your EVAP system. To troubleshoot this, replace the cap using an OEM component.

What does the p0455 code on EVAP mean?
This code is very similar to the P0455 code, expect this code means that there is a small leak. The p0455 code means that there is a big leak. You will most likely not experience any symptoms of a P0442 code other than the check engine light.
