Question about 2000 Pontiac Sunfire
Went to get car inspected today in NC. It failed this code came up P0440 Evaporative Emission Control System Malfunction. What does this mean and how do I fix this???
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.
