Which sensor is b2s1 on 1999 Ford Explorer?
I'm not a mechanic / technician but I assume that would be : Bank 2 , sensor 1 Bank 2 is the drivers side of the engine in a 1999 Ford Explorer Sensor 1 would be the oxygen sensor somewhere in the exhaust before the exhaust enters the catalytic converter ( upstream sensor )

Oxygen sensor location for 1999 Plymouth Voyager bank 1 sensor 1 needed?
There are two oxygen sensors one is called the upstream oxygen sensor located in the exhaust manifold and one downstream directly behind the catalytic converter. I think the one you are looking for is mounted in the exhaust manifold sometimes referred to as bank 1 and sensor 1 being the first in the exhaust system. Hope this helps you.
Where is the upstream oxygen sensor located on a 1999 Ford Taurus SE with a 3.0L V6 engine and how do you go about changing one if only the upstream is bad do i need to change the downstream as well?
The upstream 02 sensor is usually located shortly after the exhaust manifold, before the converter. That is the one that controls how the car runs. The downstream sensor, after the converter tells the computer if the converter is doing it's job or not. It does not affect performance, but you might have to live with a check engine light being on. There are probably 2 of each on a V6.
Where is the upstream oxygen sensor located and can you replace it yourself?
The upstream o/2 sensor is located in the exhaust system between the exhaust manifold and the catalytic converter. Some vehicles will have 2 upstream sensors (i.e. 1999 Chevy astro 4.3l engine has sensor for left exhaust manifold and another for right exhaust manifold). I am trying to find out for sure if you have to replace both when one goes bad. Bosch says both must be replaced!!!??? Oh yeah it(they)are easy enough to replace if you can see it (them).
