They all have to do with evaporative emission system leaks. You probably have cracked vaccuum hoses under the air cleaner box, and possibly under the van at the charcoal canister.

2002 dodge stratus replaced spark plugs now car wont start showing codes p0442 followed by p0456?
I'm sure the evap. codes you mentioned aren't why it's not starting. My codes (1684, p0456, p0455, p0442) were all caused by a 3/8 by 3" long hose connecting the tube running to the front of the engine to the ldp. The ldp is located on the passenger side behind and above the gas tank. The tubing is 3/8 but it's connrcted to a 7/16 nipple. Great design huh!
How do you check the codes on a Dodge Durango?
To check the code on the 2004 Dodge Durango you can also KEY from the on to start position 4 times (eg. Off to start, off to start, off to start, off) and the code should show up in the odometer reading. For example I just had the MIL come on and I did the KEY thing and found the code was P 0456. If you don't see something try turn the key again three times and then on the fourth turn leave it in the start position. It should show up. the durango need to be pluged into a type of computer that can communicate with the powertrain control module (pcm) if you have an engine malfunction light on. the drb will give you a code, the code will give you an area of the vehicle to inspect ie p0456 (large evaporitive emidssion leak detected) then you will have to inspect that system to find the cause of the code
