2003 Nissan Altima 2.5s code 0442
I bought this used car and it has 140K miles. A few days ago I got the 0442 code and thought it was a loose gas cap. I tightened the cap and cleared the code. A few days later the code returned and I smelled gas and saw a small leak around the gas tank.
Today the code cleared but I could still smell a faint gas smell. My guess is I have a small leak in the lines somewhere.
Does anyone know how to fix this? I tired to search the forum but didn't get a clear answer.
