02 Sensor Voltage via Scan When Sensor is Unplugged

Hi All,

I have an 1987 R10 5.0 with THM400 trans. The ECM appears to be working OK. I can get code 12 and I can disconnect the coolant sensor and it throws the code. My question is (when using Win ALDL) should the scan tool (more properly the ECM) be reporting/seeing any voltage if the 02 sensor is disconnected? IF the O2 sensor is unplugged, should it throw a code? Thanks in advance
