CEL after over filling tank, anyone else?

[Charlie Daubitz]

Yawn 🥱

This was the cause of my CEL wouldn't reset. A broken line fitting on the charcoal cannister on a line to the tank. I repaired it with JB Superweld light activated the picture. 2800 psi light activated clear glue that you can buildup as thick as you want and sets instantly with the supplied UV light.

I kept this one for a spare, just in case

I have a Bosch like this

, Autozone and O'Reilly won't reset any codes, my Bosch won't reset this CEL. I only overfilled it once.

Absolutely stop at 1st click. I made the mistake of "continue filling" on my 2016 F-150. That code is Permanent, meaning consumer code testers can't clear. Tank had to be dropped, new part installed, then code professionally cleared.. A $750 No No. My new Mav will NEVER be filled past the 1st click. Lessons learned.

Topping off fuel is A common cause of EVAP system damage tho

Yep, I’m with you, stop first click, fill up at half tank and never care about the clubs, EV coach thing etc. IMO life is too short for that boring grandma stuff, I’ll take the FUN route with the time I have left and make use of that sweet turbo!

I keep at least 120 miles to E as when in Dallas I don't want to be in the ran out of gas while on the longest "parking lot in Texas" (AKA LOOP 635) club!

Clear the code and see what happens. I'm one who overfills often and never had a problem with any vehicle. But some do. Anyway, if the code comes back, get it checked out. If it doesn't. Great. I find a good practice is to add fuel once after the first click. After the second click let it go. Most people who have problems actually try to stuff the tank to get every possible drop inside

It surprises me that an experienced Ford Tech would ignore Ford’s recommendation of stopping at first click. So many cases of costly EVAP related repairs would be avoided by stopping there. Why risk it? Or worse yet - encourage it?

I can grudgingly accept your “oil is oil as long as it meets Ford’s spec” argument. Although Ford’s spec keeps the optimal additive package undefined….

Note to self…our Maverick’s are designed to leave empty air vapor in our gas tanks. Maybe 1-2 gallons of potential gasoline fill.

This vapor space is to allow for fuel expansion - and to ensure liquid gas does not “slosh” up into the EVAP system lines that suck from the top of the gas tanks. Liquid gas in the EVAP system lines can damage the charcoal canister & will throw codes.

Darryl suggesting to go to a second click will NOT overfill tank to a damaging level I’m guessing - or he would not have suggested it.

But remember - Darryl has a “mechanic’s touch” or “mechanic’s feel” that many of us lack. That is why I stop at the first click

I DO have a bike mechanic’s touch though. Or used to before all the damn electronics

I stop at first click if filling at slowest pump speed. If I seldom use a higher fuel fill rate I will go at slow speed to verify the pump did not prematurely shut off which will happen if nozzle is not quite in the optimum position. The gas tank on the hybrid is pressurized to help keep the evaporation rate lower and the gas blend within spec's.

I'm simply saying that the ones that we see that have problems aren't the ones that click twice. They're the ones where the driver packs it full. As for why I've been guilty of packing a tank in spite of knowing better? 1. I haven't had any issues. 2. If I do, I know what to do. And it won't be a big deal. But again, I don't advise an owner to do it because if they have a. Issue, they're going to have to spend a lot more money.

I think you answered your own question. Why would someone who earns money repairing the fuel system say "go ahead, fill it beyond the first click" . My dad always would top off to the next dollar. So when gas was 35 cents a gallon and it would stop at 3.01 he would attempt to add almost 3 more gallons. Many times I watched as gas ran out on the ground. I learned from watching him to just STOP.

I don't suggest stuff to tear up cars . Besides, Evap concerns are not our favorite type of repair to diagnose. But I've noticed a couple of things in my years as a mechanic. You have drivers who totally ignore maintenance and common sense. I wouldn't buy a used vehicle from them unless it was at a greatly reduced price. But there are others who simply stress TOO MUCH. They are paranoid and think maintenance intervals and oil recommendations are a conspiracy to make a car break down right after the warranty. And there are those who simply maintain their vehicle per manufacturer recommendations and enjoy their vehicle. On average the ones who maintain per factory recommendations and those who OVER maintain, and freak out over 1 click vs 2 usually end up with virtually the same results long term.

As for oil meeting Spec. Labels on the oil often specifically list that it meets WSS-M2C962-A1 standard. If not, you can often research it on the oil manufacturers sight. The specific additive package need not be listed. But if the Ford standard is listed it's fine

Old habit for me - from the days of way too many pumps gushing even on the slow setting - and tripping very early.
I always stand right there - and could hear it very frequently.
Prior Rav4 was prone to it. Tank almost empty, got 10 gal - there was 3 more available minimum.
So habit was 3rd click - at least the QT pumps would do the 2nd press at slow speed - but I could still hear the problem bend in the neck.
2 click was frequently the almost one. 3rd was just to make sure I didn't mishear things.
And on that vehicle - no where near topping off to have fuel overflow. Never an issue.

Now - I've backed off to 2nd click, and still hear some pumps being a tad fast and gushy even on the slowest speed. I'm not holding it, but on the auto-hold slowest speed. I can hear the sound is still down the neck on the 2nd click when it's going slower, on those pumps that do that.
We don't have those vapor covers muffling the whole thing - can hear it very well.

The pump’s shut off sensor (click) is near the bottom of pump spout. Not much space in the fuel tank’s filler neck to take more than a few ounces more. The gas left in the pump hose will go into the next vehicle’s tank. Hope they appreciate the bit of free 91 octane upgrade
