Transmission Fluid Temperature (TFT) Sensor Construction/Operation
WARNING: This page is about a different car, the 2008 Mazda RX-8, 2007 Mazda RX-8, 2006 Mazda RX-8, 2005 Mazda RX-8, and 2004 Mazda RX-8. However, it is still accessible from the selected car via links, so may be relevant.
- The TFT sensor is a thermistor type and the resistance changes according to the ATF temperature.
- The characteristic of the resistance is as shown in the Fig 1 below: when the ATF temperature increases, the resistance decreases, and when the ATF temperature decreases, the resistance increases.
- The TFT sensor is integrated with the wiring harness component.
