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.

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

P0440-evaporative emission evap system faultthese codes can appear if you forget to put the gas cap back on or if the gas cap isn't sealing properly/seal is bad. Next is to double check the vacuum line from the throttle body to the purge solenoid for leaks. Next possibilities are a problem with purge solenoid or some other electrical connection dealing with it.
First thing I would do is make sure your gas cap is on all the way and then try replacing it then go from there.
Thanks,
Lee

    You can even try and tighten the gas cap and clear the code and go from there. Basically if its not the gas cap you may want to have a professional perform a "smoke test". They have special machines designed to diagnose this problem. Hopefully it is just a gas cap problem. Please let me know if you need any further assistance.
    thank you,

    Also to answer your other questions. the price will vary on what the problem ends up being at this point it could cost nothing and you just need to tighten your gas cap. or about 5-10$ for a gas cap. If its something more serious then obviously the cost will be more then 10$. Also you should be fine waiting a week. You've already made it this long.
    Thanks,

PO440 code is Evaporative Emission System, probably an oxygen sensor needs replacement

According to Ford Techs, check Engine code P0440, smell of Gas, High fuel intake of 1 P0440 is a small leak in the fuel system. Not necessarily fuel, but more probably the system isn't sealed. You can attempt the cap, but if you have high fuel intake I doubt its the cap. Check where cap seats for damage or rust. Check the fuel filler neck real good, they rust at the bottom and leak. Check the lines to the charcoal canister which is at the back passenger side of car. Make sure they're all on secure and check the canister itself for cracks or damage.
Do you live in farm aria? You may be able to check the fuel lines at the engine and vacuum lines. If you smell fuel in the car you may be able to check the fuel senders, but this takes a little work and mechanic capability. Under the rear cargo area, just behind rear seat is two access doors, remove the screws and lift the doors off. Look around and see if there are signs of mice, they like to chew wires and hoses, look for fuel leakage around the top of the tank. They are the common things w/o to get into the electrical switches that go with that system. you may knocked vacuum line off by air cleaner or passenger front strut area. one vacuum line in specific goes to the Canisters purge solenoid, that could because the P0440.I don't see how the plug gap or wires could because that code. They could because a P0301 P0304 misfire codes. How is the car running? Please let me know how this worked for you and please do not forget to grade my assistance so I am able to continue to provide you with better service. I will be working with you to conclusion of the issues.

Hi,

Answer to P0400 EGR FLOW MALFUNCTION P0400 EGR FLOW MALFUNCTION is a blockage code, not a compenent failure. What the computer is letting you know is that something is preventing the EGR valve from opening and closing. A sensor mounted just above or near the EGR valve checks pressure to veryify that the EGR valve is indeed doing it's job. When the EGR failes to do it's job, that's when P0400 code surfaces. The typical cause of this code is cracked vacuum hoses or clogged hoses and or components with nasty carbon buildup inside of them. Each and every vacuum line to the EGR system needs to be checked! Carbon clogging also occurs inside the throttle body where the maze of vacuum lines originate. The task of unclogging those holes on the throttle body can become tideous, but needs to be performed in order to open up the vacuum flow. Rarely does a component failue throw a P0400 code, but when it does, it's one of three things. 1) EGR valve diaphragm is cracked and leaking vacuum, 2) The EGR plenumn sensor has failed 3)The amount of voltage getting to the sensor is not enough with a certain window, and will throw a P0400 code.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

03 dodge durando w 4.7l w a p0440 engine code


first thing, disconnect your battery and clear the code. before restarting check and make sure the gas cap is tight, should click at the least 3 times. if the light comes back on check the rubber lines that connect to the filler tube and make sure they aren't dry rotted and cracking. if their are no visible issues with the lines then it is a possibility the evap canister is bad. best bet is to take it to a shop or dealer and let them run a smoke test on the system, only after you check the gas cap.

I have a 2003 dodge neon and the engine light came on but no codes accompanied it.


Hi,
Your services engine light comes on when the computer detects a fault within the engine drive ability, transmission or emission system.
Check for your loose gas cap if its not showing any code.
Do let me know if it helped. Positive feedback is always appreciated.
Thanks Kanu

Servie indication looks like transmitian code.


You need to have the car scanned and see what the codes are for the light for proper diagnosis.You can buy a code reader at almost any auto parts store for starting around $40 if you don't want to take it to a repair facility.
