The correct statement regarding a Transmission Fluid Temperature (TFT) sensor is:

c) This sensor creates a voltage proportional to the fluid temperature.

Explanation:
1. The Transmission Fluid Temperature (TFT) sensor is designed to measure the temperature of the transmission fluid in a vehicle's transmission system.

2. The TFT sensor operates by producing a voltage signal that is directly proportional to the temperature of the transmission fluid. As the fluid temperature changes, the sensor generates a corresponding voltage output.

3. This voltage signal is then sent to the Transmission Control Module (TCM) to provide essential information about the fluid temperature, enabling the TCM to adjust transmission operation based on the current temperature conditions.

4. Therefore, the correct statement is that the TFT sensor creates a voltage that varies with the fluid temperature, making option c the accurate description of the sensor's function.
