Hi,
The upstream O2 sensor is at the rear of the engine and mounted on the exhaust manifold. I attached a pic below showing the location.
On this vehicle, there are two sensors, an upstream and a downstream. The downstream is after the catalytic converter and the upstream is before it.
Let me know if this helps or if you have other questions.
take care,
Joe
