Of course it can be other issue's, but this code is most likely the fuel cap, erase the code and drive it until the systems goes through a complete drive cycle test, about 30 miles of varied driving, freeway, low speed and stop and go, if the light doesn't come back on u are home free.
My background is 20 years of electronic engine and emission control field experience and a certified smog tech for both test and repair of all car and truck lines.

Codes p0455


03 VIT
no engine option stated. hard.
0455 is classic EVAP. failure.
99.9% are loose gas cap or bad gas cap.
tighten it, reset the DTC and drive, comes back, then its real.

EVAP is the fuel tanks , venting system. its a Closed system.
now.
the code means it has leak.
in the smog station the first test is the cap is removed
and a pressure test cap inserted on the filler neck. and
we do the classic, leak down rate test.
if it fails you fail.
not surprising, if the cap is tight and new, and you fail evap
we do that test too, first. omg it does leak.
i then hold a 1/2 rubber hose to my ear and find the leak.
we use pressure at 1-2 psi on the filler neck (shop air and reg)
to apply air, and test the system for leaks.
we use dry nitrogen, for safety but if frisky?, real air works too.

if not up to all that, you can inspect every inch of the system
and might find a cracked or hose that fell off the vents.
and friends.

- Fuel filler cap remains open or fails to close
- Foreign matter caught in fuel filler cap
- EVAP canister or fuel tank leaks
- EVAP system hose leaking

What does PO 455 code mean on a 2002 Chrysler Sebring?


Diagnostic Trouble Code (DTC) P0455 "EVAP LEAK MONITOR LARGE LEAK DETECTED"

This simply means that your Evaporative Emissions Leak Detector monitor has detected a large leak in your Evaporative Emissions (EVAP) system.

It is common for this code to set if you refuel your vehicle with the engine running, forget to put the fuel cap back on after refueling, or do not properly install or tighten the fuel cap after refueling. In these cases, it can be fixed by simply installing the cap properly and clearing the code. Also, make sure your engine is turned off when refueling so it dos not happen again.

If none of the above is the cause of this code, then you either have a large leak in one of the hoses, connections, or the fuel tank itself, or the EVAP leak detection pump is defective.

What does check engine code P-0455 and P-1684 mean?


P1684 - Battery Disconnected Within Last 50 Starts

P0455 - Evaporative Emission Control System Leak Detected (no purge flow or large leak)
This indicates a fuel vapor leak or lack of purge flow in the EVAP control system. It means a large leak has been detected. The (EVAP) emission control system prevents the escape of fuel vapors from a vehicle's fuel system. Fuel vapors are routed by hoses to a charcoal canister for storage. Later, when the engine is running a purge control valve opens allowing intake vacuum to siphon the fuel vapors into the engine.

Symptoms: You likely won't notice any drivability problems.

Causes: A code p0455 most likely means one or more of the following has happened:
A loose or improperly affixed gas cap
A non-conforming gas cap (i.e. not factory/original brand)
Other leak or damaged piece in EVAP system

Possible Solutions: With a p0455, the most common repair is to:
Remove and reinstall the gas cap, clear the codes, and drive for a day and see if the codes come back.
Otherwise, replace the gas cap, and/or
Inspect the EVAP system for cuts/holes in tubes/hoses (you may hear a vacuum noise or smell fuel), repair if necessary


Test and check it. Hope this helps.

What is p 0455 means?


There are a couple valves/controls in the EVAP system. The EVAP system (hoses) extend from the engine to the gas tank. If the following information doesn't help, you'll probably need to have a dealer or repair shop to diagnose and repair.
