: "ECM?" What does this mean?

Hello,

My 92 Seville STS gives me this message ("ECM?") when performing diagnostic test. What does this mean? Maybe a bad ECM? Will check for a blown fuse.

I'm also getting a "E044" (O2 Sensor Lean) code. I'm sure they are related and the ECM is supposed to adjust fuel mixture if needed. However, not sure if the O2 sensor needs replacing or the ECM is bad and not responding to the O2 sensor.

Any help would be greatly appreciated.

Thanks in advance,
