Question about 2011 Ford Fusion
Capless gas tank causing check engine light. Cleaned had dealer reset 1 week later back on.
1st of all never bring it to a dealer--mechanics generally don\'t have experience--they don\'t pay enough for the good guys. It probably needs a new module or sensor-running a data stream with factory tools by a good shop works. And it\'s best to use new parts with electronics.

Make sure you replaced the right one there are two sensor's for the coolant, one takes coolant temp and the other one runs the fans for the radiator. Both are located on drivers side of the block. 2 wire leads on each how ever both are different in sending readings to the computer.Both look just alike also. Just make sure you replaced the right one. Or replace both.

only way to clear is with a scanner. The scanner will also give you the codes so it can be diagnosed. If its an emission issue your warrenty should cover it.

Now, in the past year, when I fill the gas tank, I can smell gas fumes inside the car (remember, it's a wagon).
I have a lot of customers that run into this problem and get the same answers from the dealers.
Given the age of the car and that it has been in a accident, here is what I would look for first.
1. First, because of the accident I would look to see if all the work was performed properly around the gas tank. Check the filler neck to make sure that all hoses and clamps are tight and in good shape, if cracked or it has any bad spots in it, replace it. The tech. that repaired the car could have missed something by accident; this is always a good place to start with by double-checking the work that was done.
2. I've had the Fuel Pump replaced twice due to recall. Another possibility, when they installed the fuel pump they may not have put the seal in right or it could have slipped. There is usually a rubber ring that goes between the tank and the pump and it might have moved during installation. When you fill the tank to the top it may come out because the seal slipped out of position.
3. I'm not sure on this model but on a lot of the newer cars they have been mounting the charcoal canister in the quarter panel next to the fuel neck but it may be hidden behind a plastic cover. The charcoal canister may have been damaged from the accident or it could just be defective and when you fill the tank up it may be going into the canister and fumes are coming from it or gas may be leaking out of it.
4. I have found that some of my customers have been over filling the tank trying to put as much as they can squeeze into the tank, this is not a good idea. When it gets hot outside, the gas expands and has no where to go except into the canister or lines of the canister, this system is not meant to handle gas, it is only meant to handle fumes. You will smell gas if you try to over fill the tank. When you fill it at the station you should let it click off. Just try rounding it off to the fifty cent mark, (example: $10.03 only go to $10.50 not $11.00) this will help you to keep from over filling the tank and neck of the tank. Over filling the tank can clause damage to the canister and components in this emission system.
These are things that the average person with some mechanical knowledge can check out on their own. After this point, it will usually have to be looked into by a fully qualified tech. with good trouble shooting skills that can follow the flowcharts to find the problem.
