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

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.

The 4 wire o2 sensor is the one I replaced.
