how to reset check engine light on 1992 Mazda mpv
When the light comes on it's telling you to read the engine diagnostic codes.
It is the port, where a diagnostic machine can be hooked up. The diagnostic will read codes from your vehicles computer. For instance if your check engine light comes on, you can plug the diagnostic machine into the data port and it will tell you why the check engine light came on so that you can get it fixed.
Diagnostic codes are generated by your on-board computer. They tell you what problems the computer has identified with your engine. The codes are numbers. The code numbers are read by an instrument that plugs into a special jack under the dash. Auto parts stores often will check your diagnostic codes for free, or you can have your dealer do it.
