My 2004 Mazda 6 had a similar problem. It smelled like gas inside the car and had code # P0456. I found that the PCV line was pinched. The line was not an Original Equipment. I replaced the line and the PCV valve. So far so good...

SOURCE: Diagnostic code P0456 for 2003 Dodge Ram 1500 5.7

P0456 = EVAP Emissions Control System Leak Very Small

Is the gas cap on tight or is the seal damaged? If it needs replacement, get it from the dealer.

SOURCE: Code P0456 on 2003 Town & Country

Below are the possible causes for your engine light and error code:

Possible Causes:

  • EVAP fuel tank or canister vapor hoses leaking or damaged
  • EVAP system component leaking, fuel cap loose or missing
  • Leak detection pump damaged or leaking

The fuel cap is probably the most common cause of this problem. It's considered part of the emission system and if faulty or not place on the filler tube correctly, it will throw an error. Best of luck with your engine light issue. Take care!

SOURCE: gas fumes inside and out side the car when it is hot outside

Try having the area that the hose was disconnected from steamed cleaned, or go to a car wash wash and spray the area. It might help, that is if you already haven't done so.

SOURCE: my check engine light came on 2003 dodge dakota

This code is normally caused by a loose gas cap or a bad EGR valve. It is the code for the evap system on your truck. You can go to autozone and they will clear the code for you if you can not do it yourself. You may need to replace the gas cap and or the EGR valve if the code comes back up, these are normally one time things due to the cap not being fully tightened.

Why would I get a gas fumes smell when car is sitting idle or just been shut off. Cannot find any leaks in gas tank or lines


gas is a very high evaporative liquid..fumes extremely strong..if overfull it will smell..and if emissions equipment has issues it will smell also.. when the engine gets hot, any gas present will vent off until the engine cools..thats the fuels evaporative nature..still keep an eye out for issues..

Fumes inside 1998 subaru forester


I had a 2000 with leaking fuel lines. There are a few molded rubber lines. Check the condition of the rubber and the hose clamps. If they are wet, you have a leak. When replacing use the good clamps that you can tighten with a nut driver

I smell gas fumes and I'm not sure where its coming from.


It's possible that you have a fuel line or injector leaking on the engine. With the engine OFF take a look near the front center of the top of the engine by the fuel lines and injectors for any dampness or strong odors. I have seen a few leaks in this area and usually you'll catch a whiff of raw gas inside the vehicle as you sit in traffic or when you walk by the vehicle after shutting it off. Because of the risk of fire you should have this smell checked out as soon as possible.Good luck, hope this helps!

Turns over well but is slow to fire off sometime. Can smell gas fumes inside the car as well as the outside. No black smoke from ehaust and no fuel leaks.


if you smell gas YOU DO have a fuel leak.... make sure your gas cap is good and or tight, also might want to look at your fuel pressure regulator.. the fuel system is pretty simple... let me know!

I am smelling gas but see no gas leaking


Is your check engine light on? Fumes rise, so if the leak is in the top of the tank or the filler neck, this would allow the fumes to escape, smelling of gas, and tripping your check engine light.
