Delphi Transmission Temperature Sensors Description There are two primary types of Delphi Transmission Temperature Sensors that monitor the automatic transmission fluid—the metal stator sensor and the plastic sump sensor. As continuous function devices that change resistance inversely to temperature, these sensors measure the fluid temperature in two transmission environments: in-line near the stator and the sump tank. A signal is provided to the powertrain control module. The stator sensor consists of: Delphi Transmission Temperature Sensors Brass or stainless steel shell Thermal grease Insulating sleeve Gasket Insert-molded connector containing a negative temperature coefficient (NTC) thermistor The sump sensor consists of: High-temperature plastic shell Patented pre-mold subassembly that contains a NTC with a crimpless conductive path Simple, lightweight, and cost-effective design Design flexibility with customized packaging of: - Mounting features - Connection system - Resistance output - Customized to match calibration criteria Capable of system integration 100 percent resistance calibration verification helps ensure accuracy and reliability Crimpless conductive path (sump sensor) enhances reliability and helps assure accuracy Delphi Corporation World Headquarters 5725 Delphi Drive Troy, Michigan 48098-2815 USA © Delphi Corporation.
