CEL after clutch replacement (P0141)
This past weekend I put a new clutch/flywheel in my car, no issues at all. As soon as I started it up the CEL came on, I expected this because I had my test pipe removed to make sure it would actually run right before buttoning it all back together. The first code I saw was a Secondary Air code, after clearing the code it never came back. The second code keeps coming back immediately after start up, a P0141 (O2 Sensor Heater Circuit Malfunction, Bank 1 Sensor 2). I replaced the O2 sensor that goes in to the catalyst, however the code popped up again immediately. Is it possible this code is meant for Sensor 1, before the catalyst? I had crimped one of the harnesses that goes to the transmission area of the car when I went to pull the transmission off, but I quickly realized it and moved the harness. Is it possible that the wires in the loom for the O2 sensor got crimped and are damaged? The car runs great as you would imagine, but I am not a fan of CEL's by any means (I mean who really is).
Any help is appreciated. Thank you guys in advanced.

The o2 sensors can be mixed up, only if they are completely unscrewed from the cat and header. The cable lengths are adequate.
If the sensors themselves were never unscrewed, then the wires cannot be mixed up. However, In this same scenario, the o2 sensors can be plugged into each other.
The ECU connectors can also be plugged into each other. Even a momentary mis-connection with the key on can fry the heater circuit in the ECU.
