Question about Cars & Trucks
Had it checked at Ford. They said there is a small air leak, somewhere. Not big enough to fix ( also don't know where it is from) So, I guess I just live with that light on or go get it turned off every once in a while? Also have a capless fuel tank. Wondered about getting a cap for it?
An air leak
Well--- let me tell you,you wasted your time at that dealer
You sound like you have EVAP System issues
You can have no vacuum leaks
The evap monitor won't run & complete
You can't go thru inspection
Motor won't run right
Fuel Trim will be effected
Gas mileage will suffer
Shall I continue
Now you see why I have issues with all dealers,that is
keeping my feelings under control
We'll continue--pure nonsense & you got the dog & pony show
If they put an Evap Smoke Machine on the vehicle & used the scan tool to command the system solenoids on & off--you would have an
answer in 15 min. --yes 15 min with you standing under the vehicle
Dealers total waste
You can not clear all data or dash light because it will come back
until evap monitor runs clean,so the dealer doesn't care,sells you the vehicle & forget it

You need to check the purge and vent solenoids for proper operation. You need to check the pressure sensor for out of range ( defective ). You need to check the filler neck for cracks and make sure the clamps are tight. You need to check the vapor lines for loose fit. I've seen at the charcoal cannister where the lines connect it may not be on strait. A smok test will reveal this if its not sealing. You may have a leaking rollover valve or fuel pump seal on top of the tank. You may just have a vacuum leak under the hood, These trucks have an Evap management valve also that can be leaking or out of specs. Look on the emmisions lable or vacuum chart under the hood. This will show you the underhood components.

It will not go off by itself,you will need to reset it by connecting to a diagnostic tool.Once cleared if there is any other problem then it will trigger the check engine light again.Hope this helps..

Try taking the gas cap off, and put it back on securely. Then have the check engine light reset. Drive on it for about 50 miles, and if does come back on continue onto other emissions related problems that link to that code (exhaust manifold perhaps).
answering this question with a vague "probably sensor has gone bad" will just have you running around in circles like a decapitated chicken. Take your time, don't rush, and don't throw parts into your car thinking it will solve the problem...sometimes the smallest mistake can turn this like on.
