CEL at 23,000

[con_fusion]

So I went out at lunch to do some running and when I started my Fusion, the check engine light stayed on solid.

 

Car seemed to be running fine so I immediately went to my dealer and talked to the assistant service manager before turning the key off.

 

Service was booked this afternoon but they can check it tomorrow. Meanwhile, he said it's ok to drive until they can check it.

 

Turning the key off and restarting did not clear the light.

 

So 2010 Fusion ... The Adventure Continues...

 

Hope to find more tomorrow.

[con_fusion]

After having it checked at the dealer...there is some EVAP problem between the filler neck and the fuel tank.

 

They will need to lower the fuel tank to replace it, whatever it is.

 

They have to order a part which they didn't have in stock. (do they ever?)

 

I don't have paperwork on it yet since the work order is still open so I'm not sure exactly the part numbers etc.

 

They'll get the part on Monday and probably get this fixed on Wednesday.

 

I'll post later when I have more info.

Argh! I had an intermittent issue with a filler neck on my 2005 Bonneville. The filler tube was exposed in the wheel well, and I drive on gravel about once a month. Long story short...rocks would bounce up and knock it ever so loose. CEL would ensue. I learned to wiggle the tube to reseat it, and I started carrying an OBD-II scanner in my car to reset it.

 

Unfortunately, this sounds more complicated that wiggling it. Thanks for keeping us updated!

[con_fusion]

Supposed to take my Fusion in to the dealer tomorrow and now...the check light has gone OFF.

 

A friend had a bluetooth scanner and we checked to see what was there. It only has the P0456 code (small EVAP leak detected) stored but no active codes.

 

Guess I'll call them and see what they say. They were talking about dropping the fuel tank to replace something but after looking at this stuff, I'm more inclined to think the canister purge valve flaked out as per TSB 11-11-28. My build date was in 11/2009.

 

Of course I'm not a mechanic so who knows. I hate intermittent problems.

 

Text of the TSB is:

So, my Fusion is at the dealer. They said since they had done a smoke test and diagnosed it already, they would go ahead and replace the part even though the light went out. They expected it would come back in the future.

 

So hopefully the technician really did a smoke test and traced it to a vent hose near the filler neck.

 

We'll see...

[con_fusion]

So I got the Fusion back and they have replaced the fuel filler pipe and hose.

 

Part # AE5Z-9034-R. This basically runs from the filler door to the tank.

 

The part # actually has two pieces to it. The fuel tank filler pipe and the fuel tank filler pipe hose.

con_fusion, did this fix the problem for good? They did not replace the canister purge valve? My car also has P0456 code. 2011 3.0l Fusion with 45k miles.

 

Thanks.

[fusionfamily]

Not unusual for the capless filler necks to leak... Replaced a few on Escapes. It's rare for the canister to have an issue... (unless you plug it up with mud or overfill your tank)

Well...a few months later I ended up with another CEL and they replaced the canister purge valve (read the post here - http://www.fordfusionforum.com/topic/8886-another-freakin-cel-at-30k/). They said they replaced the purge valve per TSB 12-3-19. The text of the TSB is listed here - http://www.fordfusionforum.com/topic/8733-evaporative-purge-valve-and-canister/

 

So did they diagnose and fix it correctly for me the first time? Not sure. They said they did a "smoke" test and found an issue with the filler pipe.

 

Ultimately ended up needing the purge valve replaced a few months later.

I just replaced my canister purge valve and it has fixed my CEL with code P0456. Here's some details for those coming across this and having the same issue.

 

This is for a 2011 v6 3.0l Ford Fusion with 41300 miles. The purge valve is located on the engine, near the throttle body. It's a tight squeeze an you'll either need a small box wrench or a 1/4" shallow ratchet. The price paid for the part from a dealer is $52. I could have got it cheaper but I didn't want to wait. It takes under ~30 min to replace, if that.

Could you post the Ford part number for the purge valve, please?

[rejester]

The purge valve is 9U5Z-9C915-H (for my car, a 2011 v6 3.0L but may work with others.)

My check engine light has been going on since around 38,000 miles. Ford dealer replaced the canister; to no avail; they are telling me now they need to hook up a smoker and perform a leak test. This is not the right procedure for a small leak. I am getting code P0456 (very small leak). I decided to hook up my OBD2 reader and leave it connected while driving to work; monitoring Evap Pressure. Highest reading was 68.5, lowest was -576 (WTF?) How can the pressure go negative? Based on the TSB I read, it seems logical to replace the Evap Canister Purge Valve rather than go leak hunting. I have the capless fuel system as well, and I know this could be a contributor, but I am thinking the valve is sending strange readings. Any comments?

[indifferent]

Capless fuel is a hug convience but i figured it will be only amatter of time until it loses it's seal. Car's have come so far mechanically with engines and trans being for the most part rock solid, it's everyhting else that stats to fail now.

I think the purge valve was like a $50 part (don't quote me though). So it wouldn't be a huge amount if you wanted to change it to see...

If your pressure went from 68.5 to -576 in the same ignition cycle, that to me sounds like a bad fuel tank pressure sensor.

[Marvin Crompton]

Have a 2010 Fusion, that has the P0456 code come up ever so often. The first time i took it to the dealer, they said it was the capless fuel filler neck that had debris stuck around the edges causeing a small leak. The code comes back every now and then so i just clean it myself when it comes back. Its a common issue. See the video below on this matter.

 

[strangedaddy]

I just replaced mine yesterday due to having the same P0456 code. When I bought the car used last year, the CEL came on after about 30 days of driving but it would go off after a couple days. It started to happen more often but would eventually go off again. After checking the fuel canister to ensure there was no fuel in it, I ordered the part from Advance Auto online for $36. It took me a little longer (about 15 min) because the bolts on the 3.0L are tucked in between the throttle body and the intake manifold. I had to wait for the engine to cool off, and I had to keep away from the throttle body housing because it was still giving off heat but I got it in and it seems to be running great. I disconnected the battery to clear the codes so I will let you know if I get any more CELs. I also noticed that my average MPG went from 27 to around 30 but that is just from the trip computer. I will take some actual readings at the pump to confirm.

[strangedaddy]

OK, so I am back again, 6 months later. Last week the "check fuel door" warning came on when I started the car. Nope, fuel door is not open, so I reset it. Then 15 minutes down the road and the CEL comes on for the first time since I replaced the vapor purge solenoid. Sure enough, the code is reading P0455 again. I find it hard to believe that the purge valve has gone bad AGAIN! Haven't had a problem since October. I've put about 12,000 miles on it in the last 6 months but it is just frustrating to try and replace the same part over and over.

[thefoeyouknow]

The purge valve is a common failure, but you've hobbled yourself with laughtermarket parts, so I'm not at all surprised you've got the same problem again (if that was ever the problem in the first place). Keep in mind that P0455 only signifies a leak in the evap system, not necessarily any specific part. P0455 is evap system large leak, or sometimes labeled as gross leak. 0456, like further above is a small leak (usually a capless filler seal). A gross evap leak, on the other hand is usually a broken or disconnected tube, a blocked open vent valve (an electrically faulted vent valve solenoid would set it's own code). In order for the system to detect a leak in the first place, the purge valve has to be working, as it supplies vacuum to the system, which is measured vs time. If the CNP isn't working, you'll get a code specifically for the purge valve. The purge valve usually sets a P0441, 0465, or 0466. Driveability diag by unskilled and/or untrained individuals usually ends in frustration, poverty, anger, and not actually ever fixing the problem. Especially with evap systems.
