Is there a way to disengage or reset the Check engine light on my 1997 F150 without paying $30 for the mech to do it? I am fairly certain I just did not tighten the gas cap enough.
My brother can turn the key on and off three times to reset his Dodge. Is there a remedy such as this with Fords?
Thanks in advance.

I had a loose cap recently (GM) and had to fill the tank before the light went away. My manual says it might take a while before the light goes off after having a loose gas cap.

unhook your battery for about 10 minutes and it will go off
Especially, if you own more than one vehicle; it might be a sensible idea to pick up an inexpensive OBDII scan reader.
You can find these readers which will allow you to read the engine codes and reset the errors for something less than $100.
If you fix one problem your self, like tighten a loose gas cap or correctly replace a defective spark plug wire; it will pay for the price of the scanner.

No matter how many times you reset it, the check engine light will still pop up in a matter of time. I have a 1997 and have been dealing with the problem for about a year now.

I had a '97 F150 and had the same issue. It always seemed to be on O2 sensor that went bad. If I remember right there are 4 on those trucks. Eventually the light will go out but the problem that made it come on will remain. It's better to get it fixed.

Take it to an AutoZone. They will tell you for free what is causing the light to come on. If it was the gas cap, disconnecting the battery like was mentioned will clear it and it won't come back. It's probably one of the O2 sensors gone bad. The read out will tell you which ones. Very easy to replace yourself if you can get under the truck. I had 2 go bad and it took me 10 minutes.

A piece of black electrical tape over the light works too...:-)

I disconnected the battery and the light dissapeared. It's been 120 miles since. Hopefully, it was the gas tank.
