PO140 Question

2001 Aero w/105k, new (cat to tailpipe)exhaust about a year ago.
Recent CEL and scanned code says: âP0140 Oxygen Circuit-No Activity Detected (Bank No. 1, Sensor 2)â (Emission status light is yellow and cat, eva and o2s are flashing). Same CEL/code returns within 10 miles after cancelling with code reader.
I replaced the first (before cat)Oxygen Sensor about 20k miles ago, so that sensor is pretty new. No drivability issues present.
Double checking to see if this code is for the same sensor or could code be indicative of bad crimp connector at a J16 junction close to the ecu plug?
