Default code P0155 - a Oxygen Sensor - options?

2000 Volvo S80 regular engine, 130k miles. Check engine light illuminates, and a scanner shows the code P0155 - a Oxygen Sensor. Clear the code and light - comes back within a few miles of operation. Car runs fine - no stumbling, stalling, etc.

What are my options?

If replacement of the sensor, I was told that there are 4 of them on the car - how do I determine which one and where it physically is located?

Does it screw in and have a plug for the wiring, or is there more to changing it?

And is there a perticular replacement brand I should use or stay away from?

That code is for the drivers side front sensor.
I would replace with OEM brand sensor.(Bosch)
The sensor screws in and had a wiring harness off of it that gets unplugged.

Thanks for the fast responce!

Please excuse my ignorance about this - but how does one gain access to the sensor? From the top, or below? Anything have to be removed to get to it?

Thanks!
Vince

Below.
Sometimes the exhaust has to be dropped some other times you can reach it easy.
