Oxygen sensor part

I have 2015 JKU currently reading error code PO157, which is the rear oxygen sensor behind the catalytic convertor. When I search online I see there are four O2 sensors in total, but when I try to locate the part I can only find one, Oxygen Sensor - Mopar (05149171AB). Is the same part used for all four sensors or should there be multiple options? Any help appreciated!

Welcome to JKF.. My information source indicates 2 different numbers; 1 is 5149171AB (upstream) and 1 is 5149180AB (downstream) If all 4 are replaced then the qty would be 2 of each. These are MOPAR PNs.
