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

The solution isn't just delete the code, need to check the sensor and fix the problem, if not, the code pop-up again.

Hope this helps.

Code po455 2004 chrysler sebring 2.4l sohc G vin code


The code is for a large leak in the fuel tank or evap system.

Some possible cause are - a leaking fuel tank, gas cap, hoses to and from the vapor canister and engine, and a faulty canister.
It's possible a valve is stuck open and allowing the engine to pull fumes in when the system is supposed to be closed, but if this were the case the computer should also set a code for that valve.

Here is the definition.

P0455 CHRYSLER 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.

Error codes p0442 & P0455


Those are both Evaporative Emission Control System related.
442 is a small leak has been detected.
455 is a bigger leak has been detected.
Check all your connections, (electrical & vacuum lines) as well as check for any cracked, loose vacuum hoses in the system, as well as clean "O" ring on your gas cap well and threads in filler pipe & make sure gas cap is tight. Do the gas cap first & see if codes dissappear, but it may take a new gas cap. These codes commonly appear shortly after getting gas, due to cap not back on tight.

I have a 2001 dodge ram with a 5.2 liter 318 engine. i checked my code & it came up as #P 0455. the problem i am having is when you first touch the gas, it has just a little bit of hesitation &...


P0455=EVAP Emission Control System Leak (Large Leak)

Possible gas cap fix, cheapest try first.

Check the gas cap thoroughly, the P0455 code your getting for the large leak isusually a bad gas cap.

Also check the lines on the canister tank,right underthe passengers side of the cab, there are two lines on top that will rotand fall off or get loose enough that they will cause that problem.

You can also check on the passengers side fender well under the hood andlook at the elbows on the EVAP valve that has the hoses that run downto the canister tank, chances are one of them is loose or bad.

Best to get a factory service manual to have handy through all of this. Promanuals.net has complete factory ones for around 20 bucks. Here is a link 2001 Dodge Ram Service Manual.

I am looking for the location of the plugs on a 2000 mitsubhi mirage with a 1.8 litre engine


Are you referring to the SPARK plugs? The Mirage's 1.8 engine does not use standard spark plugs, because it is fuel injected. It uses 4 fuel injectors that has gas hookups & electrical hookups. They are located on the head in the back.

P0455 is a EVAP system leak detected code check to make sure your gas cap is tight or if you put gas in it while it was running and can set it . First tighten the gas cap then clear the code and drive and see if the code comes back.
