To change the oxygen sensors on a 2002 Ford Windstar SE, first, ensure the vehicle is cool and disconnect the negative battery cable. Locate the oxygen sensors; there are usually two, one before the catalytic converter and one after. Use a wrench or oxygen sensor socket to unscrew the old sensors, then install the new ones by threading them in and tightening them securely. Finally, reconnect the battery cable and start the engine to check for any warning lights.
