The Coolant Temperature Sensor on a 1993 & 1994 Buick LeSabre is located on driver's side of the car under the throttle body, It is screwed into the lower intake manifold. You cannot see it without first removing the throttle body since it is hidden under it. An electronic plug is clipped to the the end of the CTS.
