Lambda Lambda Lambda - Land Rovers Only

I am reading my obd1 display for the first time on my 95 RRC 3.9, and am getting:Code 45 - Lambda sensor B - right bank
If one of these fault codes is displayed check the wiring to that particular lambda sensor.

What in the heck is this?

othewise know as a O2 sensor, should be one just before and just after each cat converter. So right side exhaust pipe, sensor after the cat is B if I remember correctly. Someone else can chime in if I am wrong.

Thank you> I have done a little research, and have learned from a previous post by Disco Mike that suggests replacing both after 75k miles, and being that I am at 120k- I am in the market for new o2 sensors. I did get the light to re set, and drove her for a while, but I am willing to bet the light will come back on inevitably.
