1993 Lexus SC400 4.0L Excessive Emissions, MIL Lamp on, missing R O2 signal

Good Evening Friends (or is it Good Morning? it's 2 AM east coast time)

Above readings were in open loop. unable to achieve closed loop until code was cleared. Code will not return for 2 trips I understand. I'm pretty certain the ECU is seeing a lost signal ...
