VR Commodore How Many O2 Sensors?

[G_man]

Hey Guys

Just wondering how many O2 Sensors are on a VR 3.8 V6 Commodore? The gregorys manual says one near the exhaust, but from what i've been reading there could be another in the engine bay?

Cheers

Pretty sure buicks have one. Ecotec's have 2. It is on the exhaust before the cat.

Only 1 02 sensor. It's down in the y piece usually.
