1996 Geo Prizm Question: Replaced o2 sensor,but keeps showing code PO141

Cleared code by disconnecting negative battery terminal,but after short time coe shows back up. -
Answer 1
There are 2 O2 sensors in your vehicle. P0141 refers to the number 2 sensor, which is underneath the vehicle. The sensor under the hood is the number 1 sensor. The sensor is the likely culprit for this code, but that cannot be guaranteed. -
Comment 1
The 4 wire o2 sensor is the one I replaced. -
