Hyundai Santa Fe (TM): Automatic Transaxle Control System / Transaxle Oil Temperature Sensor. Description and operation
| Description |
| • |
Transaxle oil temperature sensor monitors the automatic transaxle fluid's
temperature and conveys the readings to TCM.
|
| • |
It is an NTC (Negative Thermal Coefficient) sensor whose resistance
has an inversely proportional relationship with the temperature level.
|
| • |
Data produced by this sensor is used to identify damper clutch activation
and deactivation zones within the low temperature and high temperature
range and to compensate hydraulic pressure levels during gear changes.
|
Inspection 1. TCM ground circuit test : Measure the resistance between TCM and chassis ground. (Inspect the terminal connected to the chassis ground with the back of harness connector as the inspection point of TCM side.
Specifications ▷ Type : Negative Thermal Coefficient Type Temp.[(°C)°F] Resistance (Ω) Min Max (-40) -40 48153 45301 51006 (-20) -4.
