Oxygen sensors are located in the exhaust manifolds & in the exhaust pipes on most vehicles
In a 2003 Pontiac Montana, the oxygen sensors are located in two main areas: the upstream (pre-cat) sensor is situated in the exhaust manifold or just before the catalytic converter, while the downstream (post-cat) sensor is located after the catalytic converter in the exhaust system. These sensors monitor the oxygen levels in the exhaust gases to help optimize engine performance and emissions. Accessing them may require lifting the vehicle for easier reach.

where are the oxygen sensors on a 2000 Pontiac grand am and how do you change them?
In a 2004 Pontiac Sunfire, there are two oxygen sensors. One would be located in the exhaust before the catalytic converter. The other is located in the exhaust after the catalytic converter.
The oxygen sensor is located in the exhaust manifold near the firewall. It is easier to get to the sensor from under the vehicle.
The 2004 Pontiac Vibe typically has two oxygen sensors: one located before the catalytic converter (upstream) and another located after it (downstream). These sensors help monitor the air-fuel mixture and the efficiency of the catalytic converter. However, the exact number can vary based on the specific engine configuration.
There are two oxygen sensors, there is one located in the exhaust system before the catalytic converter and one after the catalytic converter.
