2011 Crosstour O2 Sensors
How many O2 sensors? One in front and one behind converter? Have conflicting responses from part stores. Dealer says converter needs replacement. $800. Where can I find good how-to for replacing?

The V6 has 3 converter (2 are primary converters). The two primary converters each have a separate air-fuel ratio sensor and a secondary heated oxygen sensor. So, 4 sensors in total.
Front primary converter sensors:
front air-fuel ratio sensor
front secondary heated oxygen sensor
Rear primary converter sensors:
rear air-fuel ratio sensor
rear secondary heated oxygen sensor
Air-fuel ratio sensors are a wide-band type of oxygen sensor.
