MIL is on, code shows 456

Small leak in the evaporative system has been detected.



Evaporative system extends beyond the gas tank I am assuming.



Any help is appreciated.



Was MIL is on, possible causes.



The MIL or check engine light on 2002 Voyager 4 cylinder came on three weeks ago. I took the car (mother in law's car) to local shop. They read the code and it said the gas tank sensor was reading loss of pressure. I bought her a new gas cap and cleared the reading. Three days ago, the light came back on. My mechanic friend said he was not very familiar with Voyagers (Chrysler).



Any clues beside taking it to dealer. Nearest dealer is 75 miles away.



Thanks

Done with new gas cap. Light stayed off for 300 miles and came back on.

The correct way to locate the leak now is by doing a smoke test, its a special machine that injects smoke into the system and any leaks will be found. But before you have someone do that remove the air cleaner assembly including the bottom piece, there is an evaporative hose that comes up from the frame (steel) and connects to a plastic hose by a one inch piece of rubber hose. Take a good look at that rubber hose for a crack, if it is replace it.
