I HAVE A 2001 FORD ESCAPE WHAT DOES IT MEAN WHEN THE EMISSION SYSTEM LIGHT GOES ON?
one of the O2 sensors is detecting higher than normal emissons. Check your exhaust system
You the two opened the gasoline filler cap on a working engine - ford human beings try this on a customary foundation - or some thing went south on you. It must be scanned to be certain what befell.
It's possible that one of the emission control parts on your car failed. The light tells you there is a trouble code store in the cars computer, normally called on-board diagnostic (OBD-II). Most mechanic have a OBD 2 scanner to retrieve the code or parts stores like Auto Zone does it for free. The code will tell you what parts failed, by disconnecting the battery will clear the light but it will come back on because the problem is not corrected
