The OBD acronym stands for OnBoard Diagnostics. A standardized way for communicating with the vehicle's computer system.
Another term that goes with this one is DTC: Diagnostic Trouble Code. These codes tell you what sensors are detecting strange readings - thus guiding you to trouble-shooting the *actual CAUSE* of the readings (don't automatically blame the sensor!!)
When the computer receives these strange sensor readings, it triggers a warning light on the dashboard. This light goes by a couple of different names: "Check Engine Light" or "Service Engine Soon" (of course some people just use the CEL or SES abbreviations creating yet more acronyms!)
This industry standard dates to the mid-90 with the second generation of the technology, so you will also see the term "OBD II".
In order to 'read' the DTCodes, you'll need a scanner. Many auto parts stores will read them for free (and then try and sell you something - like a totally unnecessary replacement sensor)
The next most critical step is to research the codes - the codes are trying to tell about some strange readings the computer received from a variety of sensors. The strange reading - for example "lean condition" bank1 - will help guide you to a true FIX.
Scanners are pretty affordable these days - I bought mine for about $40 from Harbor Freight.
Sidebar: these scanner do NOT read the ABS system codes. That's a different system and the scanners cost considerably more.

OBD Data port / data link??
Any OBD2 scanner will work.
The data link connector plug is typically located almost directly under the steering column, maybe just a bit to the left of it on the WindstarThe 2000 Ford Windstar OBD 2 port is under driver side dash below hood releaseThe 1998 Ford Windstar OBD 2 port is on bottom edge of dash; right of steering column
Trouble code P0301 means: Cylinder 1 Misfire Detected
Trouble code P0171 means:System too lean (Bank 1)
Ford Windstar was created in 1994.
Yes. The mirror on the 2001 Ford Windstar is the same mirror found on the 1999 Ford Windstar. They are interchangeable.
One that works with OBD II.
The 1994 5.0L ford Mustang and 3.8L Ford Mustang used the OBD-II connector under the drivers dash. These were the first OBD-II Ford cars. They are NOT OBD-I.
A 1995 Ford Thunderbird is OBD I , EEC IV
Do you have a 3.8 engine for a 2001 Windstar Ford Van?
The CD changer is in the center console of a 1999 Ford Windstar
