I have a 2008 Nissan armada. the check engine light came on. the code reader showed code P0442 and P0455. How do you fix this problem?

p0442 small EVAP leak detected , p0455 Large Evap leak detected . could be as simple as a loose or bad fuel cap, see a lot of aftermarket caps that fail a leak test.

I am having the same issue. Code read large evap leak. This was after I spent $38.00 for a Nissan gas cap as I was told by the Nissan dealership that after market caps cause this problem. I am not a happy camper. I drove about 10 miles and the light came back on. Now, after they hsve have my $38, they tell me that the cap won't always fix the problem. They want $118 to run a smoke test.

Quisiera saber cual es el problema de mi troca le prendio el tablero y le salio el codigo p1494 quisiera si me pueden ayudar se los agradeceria que tan dificil sera y tan caro es gracias
