Automatic transmission temperature sensor Hyundai Elantra
Location:
* The automatic transmission temperature sensor is usually located on the automatic transmission pan.
* It can be installed on the side or bottom of the pallet.
Function:
* The automatic transmission temperature sensor measures the temperature of the transmission fluid in the automatic transmission.
* It sends a signal to the electronic control unit (ECU), which uses this information to control the operation of the automatic transmission.
Types:
*Negative Temperature Coefficient (NTC) Sensors: NTC sensors have a resistance that decreases as temperature increases.
*Positive Temperature Coefficient (PTC) Sensors: PTC sensors have a resistance that increases with temperature.
Diagnostics:
* A faulty automatic transmission temperature sensor can lead to problems with gear shifting, slipping and overheating of the automatic transmission.
*Usually diagnosed using an OBD-II scanner or multimeter.
Replacement:
* Replacing the automatic transmission temperature sensor is usually a simple procedure.
* Raise the car and pump out some of the transmission fluid.
* Find the sensor on the automatic transmission pan and disconnect its electrical connector.
* Unscrew the sensor and install a new one.
* Tighten the sensor and connect the electrical connector.
*Add transmission fluid to the level.
Note:
* It is recommended to replace the automatic transmission temperature sensor at the same time as the transmission fluid and filter.
