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.

Evap emmission,control sys leak


Do not top off your gas tank. The gas is going into carbon canister which is only for fuel vapors to go into (carbon canister opening near the top of fuel neck near the gas cap). Your flooding the fuel vapor canister with liquid fuel; of course you are going to get a sensor message... 'Evap emmission,control sys leak

P0443 The fuel vapor canister reduces that gas smell on hot days outside/inside of car. The fuel vapor canister fillers bad smells from gas tank on hot days when the gas expands and burps fumes through carbon canister filter. From the canister (gas vapor fumes) goes back into the engine to be burned again...it's a closed loop for vapors to be recycled though engine. Don't worry, once the carbon canister dries out and no longer flooded with raw fuel the code should go away...just don't let the top off fuel tank back flow into the 'Evap emission control' carbon filter near the top and close to the gas cap...:)

Codigo p1440


EVAP System Vent Circuit Malfunction

This diagnosis detects leaks in the Evaporative Emission (EVAP) purge line using of vapor pressure in the fuel tank. The EVAP canister vent control valve is closed to shut the EVAP purge line. The vacuum cut valve bypass valve will then be opened to clear the line between the fuel tank and the EVAP canister purge volume control solenoid valve. The EVAP control system pressure sensor can now monitor the pressure inside the fuel tank. If pressure increases, the Engine Control Module (ECM) will check for leaks in the line between the vacuum cut valve and EVAP canister purge volume control solenoid valve.

Possible causes
- Incorrect fuel tank vacuum relief valve
- Incorrect fuel filler cap used
- Fuel filler cap remains open or fails to close
- Foreign matter caught in fuel filler cap
- Leak is in line between intake manifold and EVAP canister purge volume control solenoid valve
- Foreign matter caught in EVAP canister vent control valve
- EVAP canister or fuel tank leaks
- EVAP purge line (pipe and rubber tube) leaks
- EVAP purge line rubber tube bent
- Blocked or bent rubber tube to EVAP control system pressure sensor
- Loose or disconnected rubber tube
- EVAP canister vent control valve and the circuit
- O-ring of EVAP canister vent control valve is missing or damaged
- EVAP canister is saturated with water
- EVAP control system pressure sensor
- Absolute pressure sensor

Possible solution
- Loose fuel filler cap
- Leaking fuel filler cap


Hope helps (remember to rate this answer).

Obd-2 code p1455


DTC P1455 - Substantial Leak or Blockage in Evaporative Emission Control System

The PCM monitors the complete EVAP control system for no purge flow, the presence of a large fuel vapor leak or multiple small fuel vapor leaks. The system failure occurs when no purge flow (attributed to fuel vapor blockages or restrictions), a large fuel vapor leak or multiple fuel vapor leaks are detected by the EVAP running loss monitor test with the engine running (but not at idle).

Check this possible causes:
After-market EVAP hardware (such as fuel filler cap) non-conforming to required specifications
Disconnected or cracked fuel EVAP canister tube, EVAP canister purge outlet tube or EVAP return tube
EVAP canister purge valve stuck closed
Damaged EVAP canister
Damaged or missing fuel filler cap
Insufficient fuel filler cap installation
Loose fuel vapor hose/tube connections to EVAP system components
Blockages or restrictions in fuel vapor hoses/tubes (items also listed under disconnections or cracks)
Fuel vapor control valve tube assembly or fuel vapor vent valve assembly blocked
Canister vent (CV) solenoid stuck open
Mechanically inoperative fuel tank pressure (FTP) sensor


Check for audible vacuum noise or significant fuel odor in the engine compartment or near the EVAP canister and fuel tank

Why does my 96 Tacoma shuts off shortly after starting


Are you one of those people who TOP OFF the tank when filling up?

When the EVAP recovery system soak with few ounce of gasoline......the trap vapor will take few days escape.

EVAP system is design to handle fuel vapor. Few ounce of gasoline can damage the fuel vapor recovery relay and decrease the service live of the recovery lines.

=========

You can accelerate the process by locating the charcoal canister (near the nose of the car and same side as your gas filler door)

MOVE the car to outdoor.

Disconnect the EVAP line and let it air out by itself.

DO NOT introduce any heat source or fan to speed up the process.

Reconnect this EVAP hose and use a small amount of starting fluid at the intake manifold.


Please post more information by Clicking on the comment link.

I will follow up.

Check engine light code PO442


You likely won't notice any drivability problems. P0442 indicates a fuel vapor leak in the EVAP control system. It means a very small leak has been detected. In fact, the leak can be from a hole as small as 0.04" in diameter. 
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.

With a P0442, 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, or Inspect the EVAP system for cuts/holes in tubes/hoses.

Good luck and hope this helps
