Turbo 2.3 No Oxygen sensor cell.

So if I unplug any other sensor it will set a flashing cell(Like it's supposed to). But if I unplug the HEGO it doesn't trip a cell or even set a code(Checked codes). Just wondering if any one has had this issue.

unplugging the O2 sensor won't trip the ECU for a code. It will still idle, too. It will likely run pig rich in the off idle range, to almost WOT.

It didn't even show up when I pulled engine codes, that's normal? I figured there would be some kind of way to the computer to see if it's disconnected.
