It is screwed into the exhaust pipe between the catalytic converter and the muffler with the pigtail wires going into a heat shield under the passenger seat.

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.
The P0336 fault code on 1997 Buick Lesabre is a fault in the crankshaft position sensor circuit.

After consulting several sources, someone finally called a local Buick dealer who informed me that a 1990 LeSabre does NOT have a map sensor, it was the Mass Air Flow sensor that needs replacing.
The 1997 Buick LeSabre mass airflow sensor is located on the outside of the air intake housing. The sensor can be found on the right hand side of the air intake housing.
In the rear, of the engine, right in the center, on top of the exhaust manifold. Right where the exhaust meets the engine block.
