The left front O2 sensor would be B2S1 and is mounted in the exhaust just before the front catalytic converter. If you crawl under the vehicle and know what an O2 sensor looks like, you should be able to find it pretty quickly.

O2 Location
For clarification as some vehicles have driver on Bank #1 side and others on Bank # 2 side, RH + LH drives
- Bank 1 is always the side with #1 cylinder
- Upstream O2 sensors (sensor #1) are always between engine and CAT
- Downstream O2 (sensor #2) is always after the CAT, and before the muffler
