SomeoneElse24 Posted August 4, 2022 Report Share Posted August 4, 2022 I have a 2015 ford edge 2.0 fwd and at about 58 thousand miles on the clock it started having rough idling after filling up the tank to full. I don't overfill and tried multiple gas stations. A way around it was not to fill it up all the way but now it seems to have slowly gotten worse into a rough idle. The computer refuses to throw a code so I changed the front evap purge solenoid as a first shot but that did not remedy it. I'm looking to do the rear, thinking the vent solenoid by the canister is giving the computer the wrong info because it doesn't like a vacuum leak. I've had plenty of cars with vacuum leaks, this seems more electronic but could be wrong. Anyone have experience on getting to the rear? I can't seem to find a good diagram or video showing this, but I've heard from a few dealerships/shops that this is a somewhat common problem on these engines evap systems.

1004ron Posted August 4, 2022 Report Share Posted August 4, 2022 Probably a bad evap solenoid. What code reader are you using? Quote Link to comment Share on other sites More sharing options...

SomeoneElse24 Posted August 5, 2022 Author Report Share Posted August 5, 2022 (edited) Not sure the brand, was highly reviewed but it has no engine light or standing codes in the system when I scan. Thx for that workshop manual, I'm guessing I'll see it pretty easily once it's in the air. If it isn't that by chance, could I be looking at a vacuum leak? Car's had plugs and air filters replaced once it hit 60k just for maintenance. Could it be evap canister? Didn't think that would wear out so quick but they don't make em like they used to.

SomeoneElse24 Posted October 1, 2023 Author Report Share Posted October 1, 2023 (edited) Not sure if threads can be revived on this sight or not, but sorry for the drop. The car was in use as a daily up until now and it's finally time to rectify this issue for good. My updates for the issues are what follows. Replaced both evap solenoid and purge valve Tried different gas/stations We do not 'overfill' when it clicks it's done. Sometimes I'll cut it early but if it's above 3 quarter tank the issue presents. Is worse with ac/load on the engine go figure. still no codes, however the longft is stuck at 13.3% idle and only goes down if I step on the gas. Not sure why this is permanently stuck, it could be a software issue with the car to my scanner, but no other vehicle has ever had an issue like that. Not sure why the car would be giving so much fuel unless there's a vacuum leak in the evap somewhere, however I feel like the number would be bouncing around like the shortft instead of being stuck at 13.3% at idle. This is the only real time data % that seems off. Like last time, car has had a recent tuneup and is otherwise healthy.

SomeoneElse24 Posted October 2, 2023 Author Report Share Posted October 2, 2023 (edited) I'm not sure actually for this car, but will give it a try. I did notice I never changed out the rear evap solenoid filter? I removed the small box again and checked, but the filter seems to be in good shape inside. I only twisted the solenoid out and replaced that, so I'm unsure if maybe I should've replaced the filter along with it. Will give the maf sensor a try, I did clean the throttlebody/intake before, but I will again to be sure. Oh btw, scan tool is a ancel AD310 obd II. I could probably still hook up my computer to forscan if that will give any more information to me, as the scan tool doesn't see as much in this car as my other vehicles.

1004ron Posted October 2, 2023 Report Share Posted October 2, 2023 Thanks Haz Its around this time that most manufactures switched from MAF to MAP. The MAF is a much more fragile device and often damaged when owners attempt cleaning - if an inspection confirms its clean, I don't touch it.

SomeoneElse24 Posted October 2, 2023 Author Report Share Posted October 2, 2023 (edited) Cleaning unfortunately showed no change. I'm still trying to research more and am hitting a wall here. I tested the purge valve up front and it is working as normal. I don't have a way to test the rear solenoid if possibly it's stuck open but I did remove it to check and everything looks perfect. I have a smoke machine but this doesn't seem like a vacuum leak. Is it possible the pcm is not commanding the rear solenoid to close? I don’t smell fuel while the car is running, but still? Or bad canister? Edit- This may or may not be useful but the car was filled up normally and then sat for a week or so before I got in it again and it still had the idle issue until the tank drained to a little over 3/4.

Haz Posted October 2, 2023 Report Share Posted October 2, 2023 (edited) @1004ron: Your skepticism is well-placed and the MAF terminology in the Workshop Manual description is not correct. The 2015 Edge Workshop Manual provides no 2.0L EcoBoost depiction of Mass Air Flow Sensor location, nor any procedures related to it. Additional research on Ford's online parts-selling site yielded no Mass Air Flow Sensor shown as fitting 2015 2.0L EcoBoost, but FordParts does show an Air Charge Temperature Sensor for 2015 & later 2.0L EcoBoost in Edge and many other models... Link to this FordParts web page I have edited the previously posted Workshop Manual section to reflect this newly determined information. Good luck!

Good luck! Derp I cleaned a temp sensor?. If that's the case I don't see any other sensors to clean.

1004ron Posted October 2, 2023 Report Share Posted October 2, 2023 In that case it will have an MAP (Manifold Absolute Pressure) sensor which the ECU uses to determine load instead of the Mass Air Flow sensor. Search for a small device mounted on the intake manifold. The temperature sensor (AIT) is used by the ECU to calculate air density. I don't believe that the AIT or MAP have anything to do with the symptoms you describe - it will take more in-depth diagnostics, and possible temporarily blanking off the Evap System.

SomeoneElse24 Posted October 2, 2023 Author Report Share Posted October 2, 2023 (edited) I'm also not thinking it's the map considering it's symptoms. I may try re-ordering the rear solenoid with the whole filter box and try that since I only replaced the solenoid last time. Maybe I got a defective solenoid. If not that I guess I'm taking out evap parts until I find a broken one. Are there any other tests I could do to narrow the issue down? I've read the tanks can become warped with these kinds of issues if pressure is not released properly but my tank looks fine and fills up correctly. Gauge is accurate too. Makes me convinced something is being left open. rather than clogged. Edited October 2, 2023 by SomeoneElse24 Quote Link to comment Share on other sites More sharing options...

1004ron Posted October 2, 2023 Report Share Posted October 2, 2023 When mine had the exact same symptoms it was it was solved with a new evap purge valve on top of the engine - the error code can be either of the two valves. Have you been using OEM Motocraft parts? What error codes ? Quote Link to comment Share on other sites More sharing options...

SomeoneElse24 Posted March 26 Author Report Share Posted March 26 Re-doing a new post with new info. Problem has been there for a few years. Idle surges between 1k and 500 after fillup anywhere past 3 quarters of a tank. Goes away after a few minutes of driving normally. Sometimes lingers for a few driving sessions if not enough gas is burned off. Rear purge and filter box changed with motorcraft part, and front solenoid changed with motorcraft part. No check engine lights ever thrown. Just got forscan back on my laptop and can use that to check, but at current idle shows nothing relevant. Have not yet put gas in it again with forscan up. Any suggestions? About to replace boost solenoid due to full throttle or highway speed throttle surges as well, but seems unrelated. Car's now at 69 thousand miles, all stock otherwise. Clean air filter. This car is no longer a daily driver, and I'm thinking about getting it in the air and dropping the tank to take a look inside. Not sure where else to look. Vacuum lines all seem good. Spark plugs are 8k miles old, give or take. I changed the front solenoid after they came out with just the single part. Should I instead buy the whole octopus as they call it and change lines and all instead? It seems unnecessary as all my lines looked good, but I'm not sure anymore.

STBEAST Posted March 27 Report Share Posted March 27 I'm going to be so far of base, only because I am guessing. But if at any time the Evap Canister got saturated by fuel, (topping off, stuck solenoid, failure etc) it could cause the symptoms you mentioned. Being that it only happens when you fill up, could the canister be an issue???? Quote Link to comment Share on other sites More sharing options...
