03 Durango OBD II codes

Son-in-law has a '03 Durango wijth a 4.6 liter V8 and she is coding P0456 and P0513, where can I find a list of OBD II codes for this vehicle (I did tighten the gas cap and reset the computer)?

p0456 is a small evap leak most likely you have a cracked hose in engine compartment look for the evap service port should have a green cap on it there there are a couple of small hoses on either side the are known to get cracks in them or split trace the line the rest of the way to make sure no other cracks or splits. under car in abaout the middle on drivers side your evap canister is located there and ldp pump check those hoses also. the p0513 is a incorrect immobilizer key i would not worry about that yet it may not come back since you cleared the code but if it does just let us know and we will help out the best that we can

by the way its a 4.7
