If you can not find a fuel leak under hood, then check for a bad fuel pressure regulator. if it goes bad it will emit gas fumes under hood. is the check engine light on!! if so it may be the regulator or another leak. also check the evap system, could be a bad or broken hose ( underhood ). check all fuel lines from front to back.

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...:)

I have a 2006 GMC Canyon, 5 cylinder I am having issues with fuel it smells awful there are no leaks underneath. If you have any advice that would be great!


If you are smelling fuel in the engine compartment, and there are no leaks, it could be the vapor canister.

2002 expedition gas smell


When filling up do you top off the take or stop when the pump shuts off ? Over filling to the point the vapor canister is full of fuel ? Gas tank filler tube is rusted an leaking , Hose for evaporative emissions leaking ? Look under the vehicle at the fuel for a crack vapor canister etc... Your vehicle is a 2002 an these parts don't last for ever . Any warning light's lit on the instrument cluster ? Check engine light etc.... Do you know what a evaporative emissions system is ? It stores fuel vapors instead of venting to the atmosphere .

2002 ford taurus smell gas when the outside temperature is over 80 degrees


Fuel tanks have a vent tube and a charcoal cannister to capture the gas fumes from the tank. It's possible there is a cracked or loose hose, faulty fuel cap, bad canister or a fuel leak and any one of many connections. Investigate for sign of raw fuel along the underside of te vehicle, and in the engine compartment. Attempt to follow the smell to isolate the location of a leak.

Service engine light on, p0455,


Hi,

Improve the Fixya.com experience for everyone by voting!

P0455 = Evaporative Emission Control System Leak Detected (gross 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
All the best

2000 ford taurus gas tank has what appears to be a fitting on the top right rear that has hoses attached. there are stains and gas smell coming from this area. my repair manual mentions a plastic push...


The Evaporative Emission Control System monitors the fuel vapor flow between the engine intake manifold and the EVAP canister. The system failure occurs when a leak or blockage between the intake manifold, the EVAP canister purge valve and the EVAP canister is detected by the PCM.

Code P1443 Possible Causes:

- Pinched, blocked or plugged fuel vapor tubes/hoses (except between fuel tank and EVAP canister)

- Damaged EVAP canister

- Disconnected, cracked or cut fuel vapor tubes/hoses (except between fuel tank and EVAP canister)

- Damaged EVAP canister purge valve

Notes: Check for audible vacuum noise in the engine compartment or significant fuel odor in the engine compartment or near the EVAP canister.

On my '98 4x4, the cannister purge valve is located under the hood, mounted on the driver's side fender.

The EVAP cannister itself is located underneath the truck, in back, between the spare tire and the truck bed (have to remove the spare to get at it).

If it were me I would hold off on replacing parts...I'd drive around some more first, making sure that I don't overfill the gas tank or run it dry and making sure I replace the gas cap properly, etc. If the code returns, then its time to think repairs.

Strong odor of gasoline vapors


do u have a check engine light on? do u overfill the tank? which is to say when the filler nozzle clicks off do u still try to put more fuel in? in any event u most likely have a overloaded carbon canister, pull the canister out and check it for gasoline saturation, the carbon canister is located under the car in a tray near the fuel tank.

My taurus failed due to code p0442 ecap emiss ctl sys leak detected (small leak)


    Continuous Memory Diagnostic Trouble Code (DTC) P0442 indicates that a fuel vapor leak has been detected [as small as 0.10 cm (0.04 inch)] in the Evaporative Emission (EVAP) system.
    Note: Prior to performing the following diagnosis inspect the Canister Vent Solenoid (CV) for contamination. A situation may exist where contamination holds open the Canister Vent (CV) solenoid enough to set DTC P0442 and also plugs the port to atmosphere enough to keep system from being vented quickly.
    • After market parts and accessories nonconforming to the EVAP system specifications.
    • Damaged, cross threaded or loosely installed fuel filler cap.
    • Small holes or cuts in fuel vapor hoses/tubes (EVAP canister tube, EVAP canister outlet tube or EVAP return tube) in the EVAP system.
    • Loose fuel vapor hose/tube connections to EVAP system components.
    • EVAP system component [EVAP canister purge valve, fuel tank pressure (FTP) sensor, canister vent (CV) solenoid, fuel vapor control valve tube assembly or fuel vapor vent valve assembly] seals leaking.
    • CV solenoid partially open when commanded closed.
    • EVAP canister leaking.
  • Check for presence of fuel filler cap.
  • Verify that the CV solenoid is properly seated on the EVAP canister (if possible).
  • Visually inspect for cut or loose connections to fuel vapor hoses/tubes in following locations:
    • EVAP canister to EVAP canister purge valve.
    • EVAP canister to fuel vapor vent valve assembly.
    • fuel vapor control valve tube assembly to fuel tank (if applicable).
