Chk engine light on. failed inspection for code 0455.

Hi,
This Code can be related to a loose or bad fuel/gas cap. I'd confirm it's tight (a couple 'clicks') and not leaking - ensure you note air escaping when the cap is removed, which is normal.

It is not likely a scheduled maintenance issue. Manufacturers don't do things that way. You probably have a sensor-related issue that is affected by temperature as the engine warms up. These can be tricky little demons until and unless they become permanent and set a Check Engine light that can be decoded. Things such as the coolant temp sensor and the O2 sensors can cause such intermittent issues. If this is a repeatable condition, meaning that it occurs almost every time you drive, then a repair shop could hook the vehicle up to a diagnostic unit and monitor for the fault to occur, They can capture the data during the anomaly and try to ascertain the cause. If you are looking for a DIY solution, you may have to wait out the annoying light until it goes permanent.

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.

Hard to say. The gas cap might have been loose. That will turn the Chk Eng light on. When you filled the gas tank you made the cap tight again.

Get the codes read again if the light comes on again.

If you replaced the cap, I would say that you damaged the filler pipe, or vapor recovery line.. It is allowing air to get in the system, This system is pressurized. You may want to inspect that. Your filler pipe may be gone at the tank itself. Have a closer look and smell as you are under there. Also look for any wet spots. Good luck. Please rate solution. Cheers from Nova Scotia!!

this obd2 trouble code table can help you understand the meaning of code, for these codes, you can try,
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, or
Inspect the EVAP system for cuts/holes in tubes/hoses.

Have you Gotten Gas Lately ? A code 0455 on chrysler is usually a loose gas cap. it could be bad as well . Try taking off and putting back on.

you can try this:
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

code CODE PO455 fuel tank large leak.replace it .dont cost much.if that not it you have a evaporative leak.

P0455 - Evaporative Emission Control System Leak Detected (no purge flow or large leak)

What does that mean? 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
