2010 Maxima - 105000 miles

Check engine light is on
Computer scan states small evap leak

Advised I need a smoke test to see where the leak is, in order for the part / issue to be fixed
Car needs to drive 100 miles, and light should come off
Inspection is due to 2 months

Any help or feedback regarding this issue, or how it can be fixed would be appreciated

Can this be resolved by myself, or a mechanic needs to be the person to fix this issue.

Many thanks

 

Could be as simple as the gas cap not making a good seal. Use some emery paper on the filler neck where it makes contact with the cap gasket. Clean the gas cap gasket and apply a thin coat of Vaseline on the filler neck. Clear the code with the battery disconnected for 15 minutes. Reconnect battery and take it for a ride, see what happens. If you decide to change out the gas cap, make sure its OEM. If this doesn't work a smoke test would be the next course of action to see where the leak is coming from.

 

Thank you, will try, much appreciated
