Automatic transmission selector position sensor Ford Focus 2
The automatic transmission selector position sensor in the Ford Focus 2 is an electromechanical device that determines the current position of the gearshift lever and transmits this information to the electronic control unit (ECU) of the transmission.
Location
The automatic transmission selector position sensor is located in the compartment with the gear shift lever, under the plastic panel.
Design
The sensor is a small cylindrical component with several terminals for connection to electrical wiring. Inside the sensor is a mechanical switch that is connected to the gear lever. The switch has several positions corresponding to different positions of the gear lever (P, R, N, D, S).
Function
The main function of the automatic transmission selector position sensor is to transmit information about the current position of the gearshift lever to the automatic transmission ECU. This information is used to control the operation of the transmission, including locking gears, engaging drive mode, etc.
Consequences of a malfunction
A malfunction of the automatic transmission selector position sensor can lead to the following problems:
* Inability to change gears
* Incorrect gear shifting
* Enabling drive-away mode in incorrect conditions
* Dashboard errors related to transmission
Replacement
If the automatic transmission selector position sensor is faulty, it must be replaced. Replacement usually requires removing the center console and disconnecting the sensor connectors. The sensor can then be removed and replaced with a new one. After replacing the sensor, it is necessary to adapt the automatic transmission to ensure proper operation of the transmission.
