1994 Oldsmobile Cutlass Supreme 3.1L V6.
Dear KK: can you show me a diagram or picture of where the

is a 3.1

The 1995 Oldsmobile Cutlass Ciera question for a pic of the coolant temp. Sensor.  Sensor for the computer.(2-wire)

There is also a 1-wire sensor on the dr. side of the rear cylinder head for the dash gauge (if your car has gauges).It has a green wire coming off of it. Either sensor is tricky to get to. Taking off the air cleaner to throttle body duct can help.

Best way to reach rear sensor (1-wire) is with a short wrench.
