"DIY Knowledge", a great key to have.
My 01 Ranger gave me a "check engine light" a few weeks back. I didn't have access to an OBDII code reader at the time but nothing visual or audible was noticed. I filled it up with some fresh fuel and about a week later, just as quick as the check engine light appeared, it went away.
I just figured it was bad fuel or seeing as the tank was really low, it could have been debris or junk clogging an injector. I did have the "fuel cap" light on awhile back, and it turned out that my fuel cap wasn't on tight enough.
Well just this week the check engine light came on again. Same as last time, nothing was noticeably wrong. I picked up an OBDII code reader that was on sale at Canadian Tire today and read the code.
Turns out I have a P0442 or a "Evaporative Emission Control System Leak Detected (Small Leak)"
I have a Ford Technical Service Publication CD and I found their code charts. Much better then the code descriptions that come with the OBDII reader as the Ford ones are specific to MY vehicle.
So it turns out that it could be an issue with my fuel cap among other issues such as the canister solenoid, cuts or holes in the vent tubes, etc.
Well chances are, it's my fuel cap. It hasn't been clicking when I close it lately.
Anyway......the real point of this post is to just show others that diagnosing/troubleshooting/problem solving, whatever you want to call it, is very easy to do. Personal knowledge and experience is key to ones self being. I could have posted " I have an error code P0442...HELP". In turn filling up the site with yet another waste of space thread.
It's easy to obtain data off the net and even downloading free tools to assist you. OBDII code readers can be expensive, but just look around, you don't need anything fancy, it just needs to be able to read and clear codes.
Sorry for the long ramblings, just needed to share.
