How do you fix an EVAP check engine light?
Tightening your gas cap (and clearing the OBD II codes) can solve the problem for many drivers. However, when the check engine light does not go off—AKA the code clears and comes back—that might indicate a more severe problem in the evaporative emission system.
Can a check engine light show an EVAP code?
Good news for consumers with vehicles not showing any signs of a fuel leak: even if your check engine light is on and you find an EVAP code via the OBD II reading, it might be a simple fix. In other cases, however, it might not be.
What does small leak code mean on EVAP system?
The small leak code tells you that the leak in your EVAP system is minor. Still, if you do not want to fail an emissions test or look at an illuminated check engine light, you must find and fix the leak. As you likely know, modern vehicles have a way to minimize emissions.
How can I tell if my EVAP system is working?
If the check engine light illuminates you won’t know if it’s the EVAP system or something else until you identify the fault code. To get that code you can go to an auto parts store or take your car into the dealer. Some of the common fault codes associated with the EVAP system are as follows:
What to do if you find an evaporative emission system leak?
If you see a P0442 evaporative emission system leak detected code, you may be able to resolve the problem without much effort. The easiest solution may be to remove and reaffix the gas cap. Once you do, clear the code on the OBD-II diagnostic scanner and drive for a few days.
