SOURCE: code p0455 evap emission (large)

have the gas cap tested or just replace it, then disconnect the battery for 5 minutes to reset the code, then drive it for a few miles and see if problem comes back, if it does a trip to the dealer is in order, as this may be covered by your emission warranty which is good for 70,000 miles.

SOURCE: EVAP Emission Control System Leak (large)

Hi there:

DTC P0455 - Evaporative Emission (EVAP) System Large Leak Detected


When you start your truck. The computer sends a signal to the fuel tank vent valve to close off the fuel tank vapor system... Now, when the vent solenoid is commanded closed, the computer believes that the vapor system is now completely sealed up. The computer now looks at the fuel tank pressure sensor and measures the pressure inside of the tank.



Once the reading is taken, the computer will command the "purge solenoid" to open and pull a vacuum on the fuel tank.



If the computer does not see the pressure sensor reading change, it then assumes that the fuel cap was left off because it sees a fuel vapor leak.



The system will then retest itself after a period of time and if the same results are found, the assumption is that the customer would have already checked/replaced the missing fuel cap and there must be a bigger problem.



CONDITIONS FOR RUNNING THE DTC

Before the powertrain control module (PCM) can report DTC P0455 failed, DTC P0496 must run and pass.


DTCs P0106, P0107, P0108, P0112, P0113, P0116, P0117, P0118, P0120, P0121, P0122, P0123, P0125, P0131, P0132, P0133, P0134, P0135, P0136, P0137, P0138, P0140, P0141, P0151, P0152, P0153, P0154, P0155, P0156, P0157, P0158, P0160, P0161, P0220, P0442, P0443, P0449, P0451, P0452, P0453, P0454, P0464, P0496, P0502, P0503, P1111, P1112, P1114, P1115, P1121, P1122, P1125, P2135 are not set.


The engine is running.
The ignition voltage is between 10-18 volts .
The barometric pressure (BARO) is more than 75 kPa .
The fuel level is between 15-85 percent .
The engine coolant temperature (ECT) is between 4-65 degrees C (39-149 degrees F) .
The intake air temperature (IAT) is between 4-75 degrees C (39-167 degrees F) .
The start-up ECT and IAT are within 9 degrees C (16 degrees F) of each other.
DTC P0455 runs once per cold start.


CONDITIONS FOR SETTING THE DTC
The EVAP system is not able to achieve or maintain vacuum during the diagnostic test.


DIAGNOSTIC AIDS
To help locate intermittent leaks, use the J 41413-200 Evaporative Emission System Tester (EEST) to introduce smoke into the EVAP system. Move all EVAP components while observing smoke with the J 41413-SPT High Intensity White Light. Introducing smoke in 15-second intervals will allow less pressure into the EVAP system. When the system is less pressurized, the smoke will sometimes escape in a more condensed manner.


A temporary blockage in the EVAP canister purge solenoid valve, purge pipe, or EVAP canister could cause an intermittent condition. Inspect and repair any restriction in the EVAP system.


To improve the visibility of the smoke exiting the EVAP system, observe the suspected leak area from different angles with the J 41413-SPT.


Reviewing the Failure Records vehicle mileage since the diagnostic test last failed may help determine how often the condition that caused the DTC to be set occurs. This may assist in diagnosing the condition.


For intermittent conditions, refer to Testing for Intermittent Conditions and Poor Connections.


Hope this helps; also keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using Fixya, and have a nice day.

I would like to know what the code PO455 on a 2007 Mitsubishi Endeavor means.


Possible causes
- Missing or loose fuel cap
- Incorrect fuel filler cap used
- 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
- Fuel tank leaking
help.jpg What does this mean? Tech notes
The P0455 it's a very common code, because the code is set if the gas cap is loose or missing. Start by tighten the gas cap and clearing the code. In most cases the code can be clear by disconnecting the car battery for about 30 minutes.
help.jpg What does this mean? When is the code detected?
Evaporative Emission System (EVAP) control system has a very large leak such as fuel filler cap fell off, EVAP control system does not operate properly.
Possible symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Possible a noticeable fuel odor caused by the release of fuel vapors
P0455 Mitsubishi Description
This diagnosis detects leaks in the Evaporative Emission System (EVAP) purge line using engine intake manifold vacuum. If pressure does not increase, the Engine Control Module (ECM) will check for leaks in the line between the fuel tank and EVAP canister purge volume control solenoid valve under the following vacuum test condition.
The vacuum cut valve bypass valve is opened to clear the line between the fuel tank and the EVAP canister purge volume control solenoid valve. The EVAP canister vent control valve will then be closed to shut the EVAP purge line off. The EVAP canister purge volume control solenoid valve is opened to depressurize the EVAP purge line using intake manifold vacuum. After this depressurization is implemented, the EVAP canister purge volume control solenoid valve will be closed.

P0455 and p0442


p0455-- emission control system ( a large leak ) the most common cause is a bad seal on fuel cap, remove and replace cap, if light stats on. replace cap. if not the cap it could be any where in emission system. p0442 is--same as above. Code p0442 indicates a fuel vapor leak in the EVAP control system. To fix this problem, remove and reinstall the gas cap. Clear the codes and drive to see if the codes reappear. If the code appears again replace the gas cap or inspect the system for cuts or holes in the tube or hose. good-day !

My 2007 Chevy Avalanche failed the emission test with the code of P0455 what is the problem?


It is probably the evap vent valve. A new vent solenoid valve has been redesigned to correct the problem you are having. I would recommend purchasing the dealer component.
I hope this helps.

Ck engine is on Dealer found code P0455


DTC 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

Code P0455 evaporative emission system leak ( large leak) 2002 Mitsubishi diamante


Could be a number of things...rusty filler neck, or a bad "vent solenoid." These are more common. The evap system closes once you are driving it to send fuel vapors to a charcoal canister, and if it can't due to a leak, your check engine light will go on.
