Usually on the "Y" pipe just after the manifold connection points on a duel O2 sensor setup (one on each side) or just before the "y" pipe joins the flex pipe in front of the catalytic converter
The oxygen sensor on a Buick Rendezvous is located immediately before the converter on the driver's side. You will need either a special socket or a wrench to remove the sensor.
The 1990 Buick LeSabre oxygen sensor is located on the outside of the air cleaner housing. The oxygen sensor will be on the back side of the housing.
In the exhaust pipe
Somewhere on the exhaust system. LOOK

There will be 1 before and 1 after each catalytic converter.

the crankshaft position sensor is located right behind the harmonic balancer mounted on the timing cover
The sensor is locatedon the top back of the transmission. You have to remove the air filter, and housing to easily get at at.
