P0455 DODGE Description
The Evaporative emissions (EVAP) system is design to prevent the
escape of fuel vapors from the fuel system. Leaks in the system, ca
allow vapors to escape into the atmosphere. The leak detection system
tests for EVAP system leaks and blockage.
During the
self-diagnostics, the Powertrain Control Module (PCM) first checks the
Leak Detection Pump (LDP) for electrical and mechanical faults. If the
first checks pass, the PCM then uses the LDP to seal the vent valve and
pump air into the system to pressurize it. If a leak is present, the PCM
will continue pumping the LDP to replace the air that leaks out. The
PCM determines the size of the leak based on how fast/long it must pump
the LDP as it tries to maintain pressure in the system.

The problem is most likely to be with your vacuum line they put cheap rubber hose for this purpose. You should find a diagram at the front of the vehicle trace the hoses by this diagram. You most likely will find a bad piece of hose.

A code 455 most likely one or more of the following has happened
a loose or bad gas cap
a non-conforming gas cap
other leaks or damage pieces in the evap system
Inspect the evap system for cracks or breaks in lines listen for vacume leaks or strong gas fume smell and fix all lines you find that are damaged ..I know you say you put a new gas cap but make sure it a conforming cap..Hope this helps
