I was filling up with the car running and noticed in teh screen that it mentioned something about "filler cap open..." and then once replaced the emissions problem in screen and check engine light. I went and had it reset and the diagnosed "small leak" on the testing unit. Light was out and now back on. I had no issue before this and refuse to believe this is a coincidence. I went ot get inspected and it came out with a ODB System-Trouble code present of ; P0442. Called Volvo and they are waiving me in with the big $Green$ light that they use for airplanes. The timing of this just floors me.
That was the code that came up. I took it to my mechanic and he replaced my canister shut off valve (CSOV). It was good for @ 100 miles and then the Emissions screen popped up again (and has been on ever since). Oddly enough the "check engine" light is off now and I also lost the screen (that show clock and gear) since I got it back. I believe that he replaced the CSOV and rigged the check engine to get me through inspection (I was up against the wall for time for inspection). Since these lights came on with the filling of my tank (which I still believe there is a sensor tripped somewhere), is there any harm that can come from driving with the Emissions light still on? Even worse now, I have had a light come on recently telling me to "Service Engine - Urgent". I put a qt. of oil in and it went away. Concerned about bearings not holding pressure? Any thoughts on this light? It had come on again and it seems to be if I put the car in park and idle (after a while it comes on). Poor pressure? Thanks in advance

Yes, the flap must seal the hole or the Vapor system will generate an error code. The Flap may be damaged or the spring has broken or as you mentioned, if it's really cold, could be frozen open. Use a flashlight to examine the filler hole and see if the flap is still there. How to fix ford fuel fill inlet problem
P0496 is not alisted code.
P0455 - Evaporative Emission Control System Leak Detected Gross Leak (fuel vapors)
- Engine Light ON (or Service Engine Soon Warning Light) - Possible a noticeable fuel odor caused by the release of fuel vapors
- Missing or loose fuel cap - Incorrect fuel filler cap used - Fuel filler cap remains open or fails to close - Foreign matter caught in fuel filler cap - EVAP canister or fuel tank leaks - EVAP system hose leaking - Fuel tank leaking
There are a number of things that casue this fault code, here is some info on what the problem might be.
440 - Evaporative Emission Control System Malfunction
- Engine Light ON (or Service Engine Soon Warning Light) - Possible a noticeable fuel odor caused by the release of fuel vapors.
- Missing or loose fuel cap (most common) - Incorrect fuel filler cap used - Fuel filler cap remains open or fails to close - Foreign matter caught in fuel filler cap - EVAP canister or fuel tank leaks - EVAP system hose leaking - Fuel tank leaking
There is a check valve in the filler hose to stop fuel from coming out seems yours might be stuck , run a metal coat hangers inside the filler neck while prying open the little fill flap. see if that helps OR you are not or have no VENT to AIR in your evap system causing excessive tank pressure.
Hi, yes there is. To release the trunk - look on the centre console, just rearward of the front seats and you will notice a separate rectangular section in the plastic, if you lift this out you will find a cable release for the trunk underneath. To open the fuel filler cap manually, look inside the car just behind the rear light on the same side as the fuel filler and you will notice a flap in the interior trim, which is to allow access to the rear lamp. Open this and then looking towards the top you should see a loop of orange plastic - pull this towards the rear of the car to release the fuel filler.
Hope that helps Matt..
first make sure theirs enough gas in the car now, about 5 gallons. next open the gas door, then the cap. next put your ear to the open fule filler neck. then have someone put the key in the "on" position so teh dash lights up and all, but dont start. this should trigger the pump to start, if you can hear a buzz then the pumps on and working, if not the pump is dead.if this is the case just be sure by checking the fuses to confirm. only way to get to the pump is drop the tank. also dropping the rear exhaust helps too.
you may need to call a lock smith. if you attempt to remove the cap by force you will damage the filler neck adn cause an evap system leak. if you cut the cap off i would be concerned with debris falling into the fuel tank and causing drivability problems not to mention the possibility of making a spark at the top of you fuel filler neck,.... well you see where that is going. maybe there is a number stamped on teh cap near teh key hole that would be helpful to teh locksmith.
