Hyundai Santa Fe: Automatic Transaxle Control System / Transaxle Oil Temperature Sensor. Description and operation
Hyundai Santa Fe (TM) 2019-2025 Service Manual / Automatic Transaxle System (SBC) / 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.

Hyundai Santa Fe (TM) 2019-2025 Service Manual: CVVT (Continuously Variable Valve Timing) System. Description and operation
Description Continuous Variable Valve Timing (CVVT) system advances or retards the valve timing of the intake and exhaust valve in accordance with the ECM control signal which is calculated by the engine speed and load. By controlling CVVT, the valve over-lap or under-lap occurs, which makes better fuel economy and reduces exhaust gases (NOx, HC) and improves engine performance through reduction of pumping loss, internal EGR effect, improvement of combustion stability, improvement of volumetric efficiency, and increase of expansion work...

Air bag collision sensors
WARNING
To reduce the risk of an air bag deploying unexpectedly and causing serious injury or death:
Do not hit or allow any objects to impact the locations where air bags or sensors are installed. Do not perform maintenance on or around the air bag sensors. If the location or angle of the sensors is altered, the air bags may deploy when they should not or may not deploy when they should. Installing bumper guards with nongenuine Hyundai or non-equivalent parts may adversely affect the collision and airbag deployment performance. Press the Engine Start/Stop button to the OFF or ACC position and wait for 3 minutes when the vehicle is being towed to prevent inadvertent air bag deployment. Have all air bag repairs performed by an authorized HYUNDAI dealer.
