Further understanding your check engine light

https://www.motorcraftservice.com/vdirs/retail/default.asp?pageid=diag_theory_retail&gutsid=diagsheet&menuIndex1=18

If the link does not bring you directly to where it should (doesn't work for me),

Click on OBDII Theory & Operation
That will bring up a page with a bunch of links divided by model year (MY).
Click the appropriate one for your year and download it.

The guides are very handy in understanding why check engine light come on, what triggers them and such. It's an invaluable resource for everyone/anyone.
