Automatic transmission temperature sensor for Citroen C5
Function:
The automatic transmission temperature sensor measures the temperature of the working fluid in the gearbox. This information is sent to the automatic transmission’s electronic control unit (ECU), which regulates fluid temperature to ensure optimal transmission performance.
Location:
The sensor is usually located in the automatic transmission oil pan or directly in the transmission housing.
Type:
There are two main types of automatic transmission temperature sensors:
* Resistive sensors change resistance depending on temperature.
* Sensors with thermistors have a temperature-sensitive element that changes resistance in proportion to temperature.
Part code:
The part code for the automatic transmission temperature sensor for Citroen C5 may vary depending on the year of manufacture and model of the car. Some common part codes:
* 9676344980
* 9682106380
* 9682238780
Signs of malfunction:
Possible signs of a faulty automatic transmission temperature sensor include:
*Check Engine light comes on
* Strange behavior when shifting gears
* Transmission overheating
* Low fluid pressure in the automatic transmission
Replacement:
Replacing an automatic transmission temperature sensor requires appropriate experience and equipment. Usually you need:
* Drain the automatic transmission fluid.
* Disconnect the electrical connector from the sensor.
* Unscrew the sensor using a special tool.
* Install the new sensor and tighten it to the required torque.
* Pour fresh fluid into the automatic transmission.
* Reset fault codes in the automatic transmission ECU.
Recommendations:
* It is recommended to have a qualified mechanic replace the automatic transmission temperature sensor.
*Use only a high quality sensor from a reputable manufacturer.
* Regularly check the level and condition of the automatic transmission fluid to extend the life of the temperature sensor.
