No O2 Voltage

My 94 Ranger 3.0L 5 spd is setting no KOEO or KOER codes in the computer, but when I monitor the realtime data, there is no voltage output from the bank 1 O2 sensor. The bank 2 O2 sensor shows the proper voltage out. Shouldn't this condition be setting a fault code in the computer?

Welcome to FTE!

I would think that no voltage signal from an O2 sensor would throw a code, yes.

I've read that the o2 sensor will not show voltage until it has reached 600 degrees farenheight. I read that in a hanes manual for 93 to 99 rangers. I believe that is the same bank1 you discussed.
