CHECK FUEL CAP indication won't clear!

Last week I got the "CHECK FUEL CAP" indication on my 12 month old 2005 Honda PILOT with 10,000 miles. The manual instructions for this message are:

1) Turn the engine off
2) Confirm the fuel cap is installed. If it is, loosen the cap, then retighten it at least 3 clicks.
3) When you restart the engine, the message appears again. To clear it, press and hold the Trip/Reset button until the message is replaced by the odometer/outside temperature display.
4) If the system still detects a loose or missing fuel cap, the Malfunction Indicator Lamp (MIL) comes on. Turn the engine off and check or retighten the fuel cap at least 3 clicks.
5) The MIL goes out after 3 days of normal driving once the cap is tightened or replaced. If it does not go out, have your dealer inspect the vehicle.

I'm not an idiot, but I feel like one because I can not clear the message. I've held the Trip/Reset button for 20-30 seconds but I can not get the message to clear. The MIL has not come on yet, so I don't think there is a real problem.

Has anybody experienced this message? Does anybody know how to really clear this message? What am I doing wrong? :confused:

Loose gas caps will trip the check engine light on most cars with an OBD2 code of p0446. Since I haven't experienced the loose gas cap syndrome with the Pilot yet I haven't had your experience.

But if you go to an autozone they'll read the codes for free and clear them if you want to them to.

Why go to AutoZone? The car's covered by warranty. If you are going to have it looked at , how 'bout the dealer? Am I missing something?
Convenience! Some Pilot owners live in the suburbs or small town whereby no access to Honda dealer service center unless they drive 50+ miles or more.

I did and there is what I learned..
1. Dont do 3 clicks do more than that...
2. The check engine lite clears after some time (its in the manual after how long)

mine is now obviously reset. no more light on dash. I simply disconnected negative battery cable for at least 25 minutes--------LIght hasnt came back on. My vehicle is a 2003 taurus single OHV v6 ------- ford taurus. The make and model, however, probably has nothing to do with it----------the technique is what obviously works!!!!

I think that is just on the '06. I have an '05 and I accidentally left the gas cap off totally the other night. I had to leave the gas station quickly because there was a tractor trailer driver trying to manuver his rig around the pumps and was practically touching one of them. He didnt look like he knew what he was doing so I got the hell outta there............lol.
Anyway, no lights when the cap was off completely. Should I have seen one?

I normally do 8 clicks for luck! he he he...

My wife says I am obsessive. As I am replacing the gas pump, I will continue to turn (click) the gas cap. She says that she has counted over 25 clicks (altho I seriously doubt that).

Check Fuel Cap won't clear

I just came back from the dealer after having my SRS indicator fixed. Now I am having the exact same problem as Bluish. I followed the same procedure which is spelled out in the manual, and the message won't go out. The frustrating part of this message is that it doesn't allow me to view my odometer/trip meter or outside temp until the dealer can fix it.

I'll post the results after a visit to the dealer on Monday.

Cheers

Not necessarily. The system tests whether the gas cap is holding pressure by firing up the leak detection pump periodically. The pump fires up, pressurizes the system, and measures whether it holds x pressure for y minutes. If so, pass.

Its possible that during the whole time the cap was off, the self test hadn't occurred. Drive around all day like that, and you will see the light come on.

If the light is staying on, it would indicate that the condition that triggered the problem has not cleared. 3 good self tests in a row clears the light.

Well, my '06 Pilot had that "check fuel cap" message come on at about 2500 miles. Following the reset procedure as outlined in the manual is a waste of time and will only piss you off further. I called three different local dealers who told me to wait anywhere between 3 and 14 days for the message to clear by itself. After two weeks, it was still displaying every time the vehicle started so I made a appointment to take it in. The dealer kept the car for the day, checked everything they could think of checking (including the gas cap), found no stored codes, reset the light and called me to announce everything is wonderful. Sooooo, I asked, why did the message come on. The best they could offer is that this particular dealer sees it in Pilots more than any other and usually has no direct cause. The service manager suggested tightening the cap "only" 4 clicks after fueling; more can prevent good sealing. Sounded bogus and a big reach, but I now it has been 3 months later and almost 4,000 mi and (knock on wood) no repeat.

My "MIL" came on last year and stayed on for over a week of long distance driving. After I called the dealer and made an appointment, it went out:8:

The dealer agreed with me I probably got water somewhere in the system after "punching it" on an expressway on-ramp with a cold engine after a warm, humid night.

I have an OBD-II scanner... so, I can clear it. If you go to autozone, you can clear it with their borrowed scanner too.

My new 2006 Pilot EX with only 400 miles on it now has the check fuel cap problem! We can't get it to clear. From viewing this forum it looks like it is a common problem. It's too bad a brand new car has to go in for service after two weeks. Oh well. I'm still enjoying my new ride!

That is what the manual says.

"When you restart the engine, the message appears again. To clear it, press and hold the Trip/Reset button until the message is replaced by the odometer/outside temperature display."

You could press and hold the trip reset button until you were blue in the face :3: , but the message would not clear.

"If the system still detects a loose or missing fuel cap, the Malfunction Indicator Lamp (MIL) comes on. Turn the engine off and check or retighten the fuel cap at least 3 clicks."

My MIL never came on.

My message cleared on it's own. Didn't do a thing. Just started it up this morning and it was gone. I forgot to mention it did come on with about 7/8 tank of gas, and now the tank is half full. Now if you could all tell me where did all my gas go? I've only driven 140 miles since last fill!!

According to my mechanic, the "check fuel cap" warning message will go away when the computer runs and passes its next test. This test will only occur when there is between 1/2 - 3/4 tank of gas, and the operating temperature is b/w 70-80 degrees, which is at least 10 degrees less than the external temperature.

Basically, the advice posted in this thread is accurate. It's an annoyance more than anything else, but its nothing to worry about unless you get the dreaded "check engine light". The "check fuel cap" message should go away by itself eventually. It did for me after 2 weeks.

'Check Fuel Cap' flashed today

I have 2800 miles on my 2006. The 'check fuel cap' light flashed today and after resetting is still flashing upon starting the vehicle each time. This is the first time in nearly 100,000 miles and 2 Honda Pilots that I have ever had a problem with a Pilot. The cap has never been loose so this is a malfunction. I will not take it to a dealer as I refuse to let this people touch my truck. I'll keep an eye on things here and see if I can figure it out myself.

I was pretty anxious too when I received the CHECK FUEL CAP message - it went on for almost 2 weeks and 2 fill ups. But the message did go away, just like my mechanic advised. As soon as the conditions are optimal (and baring any true issues) your message will clear as well. It has been several months and no such message has ever returned.

This recently happed to me. I followed the directions in the owners manual to clear the message but it did not solve the problem. After about 2 weeks and 2 fillups the problem went away. Needless to say, I checked the gas cap several times, clicked it 4 clicks, and just waited for it to clear by itself. Not worth mentioning it to a dealer unless it never goes away.
