Question about 2007 Ford Explorer Sport Trac
First a question for you? Intake side or exhaust?. Most cars are just a bolt-on type of o2 sensor. If you know which one then simply unbolt it after disconnecting car battery ground and disconnecting o2 sensor. Some sensors from autoparts stores Dont have original plug/jack. You will have to splice the wires/jack to the new one. But if just trying to pass smogcheck I recommend a full tune-up including fitlers for motor and a fuel system treatment. If diagnostic computer says replace probly just replace. Too many things can fail a smog check but no reason stated so this is all I can really say without more info. Good luck.

Reach up there with a 22mm oxygen sensor
wrench & unscrew it
If it is a rear one, it is in the open in the converter
