Default 02 Sensor Voltage Questions

***UPDATE***
I guess I was being somewhat impatient? I figured that I had put at least 100 miles on since I installed new oxygen sensors. Was about 3-4 weeks ago. OBD reader confirmed on the last 3 trips I took today that all O2 sensors passed, and evap system and cats all reported normal. Guess the ECU was just doing its thing...

Hey All,

Quick question about sensor voltage. Replaced my front OBD2 Sensors awhile back and managed to get rid of the CEL codes my Disco was throwing. I was running a test this morning everything seems normal from what I can tell. However every check that was run on the sensors turned up: TID $08 Maximum sensor voltage with a reading of 0.

Here's the voltage for the Sensors- I've included fuel trim info if that helps at all...as you guessed, I'm completely new to this.
B1-1 0.14V STFT 1.56%
B1-2 0.58V. STFT 99.22%
B2-1 0.12V. STFT 2.34%
B2-2 0.64V. STFT 99.22%

Other Report about fuel trims
B1 -STFT 8.59%
B1 -LTFT 0%
B2 -STFT 13.28%
B2 -LTFT 1.56%

Batt Voltage is 13.3V
I used a second OBD2 reader that I've got on hand, and the O2 sensor check passed clean not showing any issues...

What exactly does that mean? Everything else was green and good to go...TIA!
