probably on dash
The Crank sensor in my 91 LeSarre Limited is behind the Harmonic balancer pulley....there are fins on the back of the pulley that line up with the sensor.
I can't speak for the Gen I Solara but suspect the location is the same or similar to the Gen II. On the '04 and later car the auto headlight sensor is on the top of the dash, driver's side. There are two dark 'bumps.' The headlight sensor is the one nearest the center of the car. The other is for the auto climate control. BTW, the name "twilight sentinel" is a General Motors label. Toyota just calls it an "Automatic Light Control Sensor." Cheers

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.
Oil level sensor is on side of oil pan.
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.

The P0336 fault code on 1997 Buick Lesabre is a fault in the crankshaft position sensor circuit.
Don't think yours will have a MAP sensor. It will have a MAF sensor, and it is attached to the air filter housing.
The IAT sensor is located on the intake manifold air cleaning housing or air duct.
