There is a slight possibility there maybe a leak in one of the fuel lines or in the top of the tank itself. Do you ever smell fuel? If you can get the car into a clean garage, lay some newspaper or cardboard under the car and with the garage door open WIDE run the car for about 5 minutes, then check the paper for any fluid drips. Try to whiff the scent of the fluid to your nose (try not to inhale it directly) and see if it smells like gasoline. Remember the location in which you found the leak and take it to a mechanic to have them look into it thoroughly, especially in the area that you found the leak. That's just one idea you can try. It'll also help you see if your car is leaking any other fluids also. I hope this helps and don't forget to rate!

One easy thing to do that might fix this problem is to go and buy a new gas cap for the car. If the gas cap seal is worn it will set the P0440 code. When you start the car, the evaporative system will pressurize itself and if it can't hold pressure it will set the P0440 code. The gas cap seal is part of the evaporative system.

Good luck!

It is coming up with p440 code


P0440 - Evaporative Emission Control System Malfunction

This indicates that a part of the EVAP control system is no longer fuctioning correctly. The EVAP system consists of many parts, including (but not limited to) the gas cap, fuel lines, carbon canister, purge valve, and other hoses. 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 P0440 could mean one or more of the following has happened:
* The gas cap is not installed or working properly
* The purge solenoid has failed
* The canister is plugged and not working properly

Possible Solutions: With a P0440 OBD-II trouble code, diagnosis can be tricky at times. Here are some things to try:
* Remove and reinstall the gas cap, clear the code, and drive for a day and see if the codes come back.
* Inspect the EVAP system for cuts/holes in tubes/hoses
* Inspect for damaged or disconnected hoses around the Evap purge solenoid
* Check and/or replace the sensor
* Check and/or replace the purge valve
* Have a professional use a smoke machine to detect leaks

Other EVAP DTCs: P0440 - P0441 - P0442 - P0443 - P0446 - P0453 - P0455 - P0456
