On a 2001 Buick LeSabre, there are typically two oxygen (O2) sensors. The upstream O2 sensor is located before the catalytic converter, attached to the exhaust manifold, while the downstream O2 sensor is positioned after the catalytic converter in the exhaust system. These sensors monitor the exhaust gases to help optimize fuel efficiency and emissions. To access them, you'll need to lift the vehicle and may require special tools due to their location.

where is the o2 sensor located on a 1992 Chevy s-10 4.3 ?
To install O2 sensors on a 1996 Buick Roadmaster, first, ensure the vehicle is cool and safely elevated on jack stands. Locate the O2 sensors, which are typically found on the exhaust manifold and the catalytic converter; disconnect the electrical connectors and unscrew the sensors using an O2 sensor socket or wrench. Install the new sensors by threading them in and tightening securely, then reconnect the electrical connectors. Finally, clear any diagnostic trouble codes (DTCs) from the vehicle's computer, if necessary.
