Well I looked into it more. Some sites say that the P1443 code deals with some other stuff. One guy said that you need to replace the emissons control valve and thermistor and it solved the problem. Another guy said that the gas cap would be the first thing to replace. I have not looked around a Ranger lately. My Sable's gas cap was pretty easy to change. It had a little ring that attached the cap to the cap and went all the way around the cap as one piece with no openings so you could easily open it up to get it off the cap. I put the cap and ring in some hot water and it easily popped off. I then put it on the new cap and reinstalled it. Maybe took 10 minutes tops.

You might try disconnecting the battery and reconnecting it. If it is just a one time error, the check engine light will not show up again. You could also call the dealer and ask for a service tech to help withe the strange error code. You're probably going to be fine, unless your in California, and they are sooo picky about emissions.
