Where is the oxygen sensor on 1997 ford taurus wagon 3.0

You need to find out which oxygen sensor needs to be replaced, your vehicle could have 2 or 3. They are located in the exhaust system either in the exhaust manifold or the exhaust pipe before the catylitic converter and one after the catalytic converter. http://www.rockauto.com/en/catalog/ford,2005,freestar,3.9l+v6,1430707,exhaust+&+emission,oxygen+(o2)+sensor,5132 Where is the o2 sensor on 2005 ford freestar 3 9

Try you tube !

bank 1 exhaust is the rear manifold towards the windshield side. Follow the exhaust down. There should be one oxygen sensor before the catalytic converter and a monitor after the catalytic converter. Be Careful.. they look the same.

this system has an obd2 system and the car should have 1 sensor for each bank and 1 sensor in front of the cat so 3 sensors.

mcdevito here, You"ll need a special socket to change the Oxygen Sensor, also some anti lock solution and the car cold.

And you have changed the fuse?
