2007 Hyundai Sante Fe P0157 O2 Sensor Replacement Bank 2 Sensor 2

In this video I show the location of Bank 2 Sensor 1 and Bank 2 Sensor 2 O2 sensors on a 2007 Hyundai Sante Fe 2.7l engine. This is a friends car and she had a P0157, which indicates Bank 2 Sensor 2 Low Voltage. Not always, but this generally is a sign the o2 sensor has gone bad. Hope the video helps!
