I have a 2003 dodge durango. My check engine light came on & the following codes came up: P0442, P0455, & P0456. My truck now takes too long to start and shuts off immediately or runs for about 5 seconds and shuts off. Can anyone help please? Thank you.

ok code po455 is a code for the evaporative control monitor,for this i would suggest you check the dealer because its a very large leak in the evap system,and for the po456 which is a very small leak in the evap system
Usually this P0456 code is caused by an incorrect or faulty gas cap. Filling
the fuel tank with the engine running could conceivable cause this code as well
or if the cap wasn't properly tightened. Any of the following could also be
A small leak in any of the EVAP hoses or fuel tank hoses
I suggest check the lines and flow it down to the ldp (leak detection pump) that is just behind the steering gear under the van It has a wire connector and 2 large EVAP hoses. look for any split or crack then follow the lines back to the tank. Even a small crack is a leak.
Hope helped with this. Remember rated this help. Good luck.
