Help: P0440
I've checked all the hoses and nothing is disconnected. One thing to note is when ever I refill my gas tank and crack the gas cap I never have a pressure differential. All the cars I have ever driven when I crack the gas cap you can hear air being sucked back in? This makes me think I either have a serious leak or its the after market gas cap I have on. I only get the P0440 code and nothing else. The Camry is a 2000 XLE V6 with 72,000 miles. The cars in good shape no rust so I find it hard to believe something major would be worn out.
