How many miles are on your truck? Might be time to replace the O2 sensor.

Thanks for the info.

BTW, my neighbor, the Ford mechanic, calls the check engine light the "Check Money Light". It usually means there is a sensor failure, as previous posts mentioned, but its easy money for the mechanics if the owner has no clue on how to check it and fix it themselves. I personally had a nagging Check Money Light due to an O2 sensor that kept failing, but the car still ran great. Fortunately, after about two years, the damn light finally burned out!

NYS inspection would fail it and have to get it fixed within 30 days so you can drive legally again after that if you get caught you get a $80 ticket and still have to fix the problem!

Hey, I've got a 2001 I don't know how many miles, I'm Female who hasn't gotta clue, filled up yesterday, light turned on today, check the seal on the gas cap, and re tightened it. Light stayed on. Took to Autozone to read code, checked gas cap, then tech said there was not power, so no code could be read. He asked if the cigarette lighter worked, there's 2 and only 1 works. He suggested the bad fuse for the lighter could be sending this service engine light.

According to this diagram the lighter is fuse 3. Am I looking in the right place? or should I look at the DTR, Fuse 5?

After reseating the gas cap it may take a few times driving and shutting off for it to turn off. Since it happened right after a full up, probably was just loose or seated incorrectly.
