I'm getting error codes 442 and 456 on my 2003 Chrysler Town and Country. I can see no bad hose connections or cracks in the EVAP system. I've heard that the gas cap can be a problem.
Ideas?
Could be the gas cap. Do you fill the tank with the engine running?
Otherwise, check the hoses near the Evap canister. I have 2003 T&C and had the small leak and large leak codes. I looked at the evap cansiter and the hose coming from the fuel tank vapor line had a huge crack in it, to the point it had fallen off the evap caniser. I trimmed the end of the hose and reconnected and voila, no codes.
The evap canister is on the driver's side of the van, underneath, slightly behind the drivers seat.
BTW, to clear the codes without an OBDII reader, remove the negative cable for 5-10 minutes (15 to be safe). The computer resets and clears the codes, except for one that it sets saying loss of power to the memory.

Same error codes. Just found out, say I need a smoke test.
My 2002 Town and Country is showing same codes. Was wondering what does gross leak no flow mean? and could this cause my RPM's to bounce sometimes after starting the van? I have replaced the fuel pump, fuel filter and spark plugs. Ran injection cleaner thru a tank of gas and it still wants to surge every now and then doesn't matter what time of day.
