Hyundai Santa Fe 2003 2.7 V6 O2 sensor issue

Question

Getting PO152 and PO154 which says "Bank2 Sensor 1". Can you help me find where that sensor is located and (if possible) the Hyundai part number. Sourcing the sensor gives wildly different prices so I need to be sure

Thanks

David

Answer 1

P0152 H02S circuit high input Bank 2 Sensor 1

P0154 H02S circuit no activity detected Bank 2 Sensor 1

Bank 2 is located where cylinder 2 is located and the other would be Bank 1, Sensor 1 are the upstream 02 sensor this is before the catalytic convertor.. P0152 and P0154 somehow there is bad connection either at the harness or along the harness to even internal of the 02 sensor.

Standing in the front of the vehicle the 02 sensor  before the catalytic convertor is Sensr 1 or the upstream 02 sensor
