check engine light code po440A
 

I have a 00" monte carlo ss and i have had this check enigne light po440A which is evap system code. now im starting to smell a strong fuel odor. i have been checking all the fuel lines and i cant find anything. any1 run into the same problem before.. thanks..

I throw the P0455 code, evap canister leaking. What is the P0440A code mean, do you know yet?

ya the po440a is evap system code.i found a crack in the fuel pressure hareness so i replaced it, only 25 bucks, then turned off the light. but i really didnt find anyelse on the fuel lines ..yet..

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
• A Leak in fuel system (Fuel lines ect.)

In my car I replaced the gas cap then worked from there since that was the least expensive. Came to find out it was the purge solenoid which you have to drop the gas tank to fix. That problem is a pretty common issue with our cars. If you take it to a shop it will still be in the $200 or $300 more cause of labor. Hope that helps

ya the light has not came back on ,so we'll see. but before replacing the purge solenoid were you smelling a odor of gas inside your car.because the other day i was smelling a odor of gas in my car, do you think that could be it...thanks

I did but my main symptom was that when I went to the gas pump the auto shut off on the pump would go off when I only had like a 1/4 of a tank in there. It wasn't just one gas station either it was at every one I went to. I could still pump gas just had to do it slow and stop every once and a while to let it settle in the tank. What was causing it to do that was the solenoid not venting the tank.

oh okay...well like 5 months ago i had to replace my fuel pump..dunno if that has anything to do with it..but im not getting that symptom that your talking bout of the auto shut off on the pump..but im getting tried of that the po440a code popping up ...next im gonna change my fuel cap..so well see..thanks....

that would prolly b the cause of ur fuel smell
