Circuit/System Description
WARNING: This page is about a different car, the 2007 Suzuki XL7. However, it is still accessible from the selected car via links, so may be relevant.
The transmission fluid temperature (TFT) sensor is installed directly in the transmission valve body (V/B). The TFT sensor input/output circuitry consists of an oil temperature sensor signal (-) (OTG), and an oil temperature sensor signal (+) (OT). The sensor converts the transmission oil temperature inside the transmission into an electrical signal and transmits it to the TCM.
