Toyota Camry automatic transmission selector position sensor
The automatic transmission selector position sensor is an electronic component that detects the position of the automatic transmission selector and transmits the corresponding signal to the electronic control unit (ECU). This allows the ECU to control the operation of the transmission, preventing the vehicle from accidentally shifting gears or moving when it is in park.

Functions:
* Determines the position of the automatic transmission selector (P, R, N, D, etc.).
* Transmits a signal to the ECU to control the operation of the transmission.
* Prevents the vehicle from moving when it is in the parking position.
Symptoms of malfunction:
* Difficulty shifting gears.
*Transmission does not shift to desired mode.
* The automatic transmission selector position indicator on the dashboard flashes or does not show the correct position.
* The car can move even when it is in park position.
