Question about 1997 Jeep Grand Cherokee
It is after the converter ,make sure you check the wiring to the sensor and make sure the connectors are free of corrosion and none of the pins are backed out. And if the converter was punched you would diffinetely fail an emissions test

First of all if it is a 6 cylinder its an inline engine (4.0L). The reason I bring this up is it changes your O2 sensor configuration. Bank 1 sensor 1 ( there is only one bank because only 1 manifold) is the primary O2 sensor controlling the air/fuel ratio dependant on other sensors. Bank 1 sensor 2 is After the cataylistic converter. Depending on the code if low input or high input could be wiring and not a sensor at all. Also a low flow or high flow could indicate somebody previously "punched" the converter out or it is getting clogged due to age and mileage. Hope this helps.
