Selector lever position sensor, automatic transmission Kia Sorento
Target
The transmission selector position sensor (PRNDL) detects the position of the transmission selector and transmits this information to the transmission control module (TCM). This information is used to control starter interlock, transmission operation, and other shift-related functions.
Location
The automatic transmission selector position sensor is usually located on the gear selector housing or directly below it.
Operating principle
The automatic transmission selector position sensor works as follows:
1. Mechanical contact: When the gear selector is moved, it moves a mechanical lever or pin connected to the sensor.
2. Electrical Contact: A mechanical lever or pin moves in a manner that changes the electrical contact within the sensor.
3. Signal: Changing the electrical contact generates an electrical signal corresponding to a specific gear selector position.
Signals
Typically, the automatic transmission selector position sensor produces several signals to indicate different gear selector positions. Typical signals include:
*Parking (P)
* Neutral (N)
* Reverse (R)
* Drive (D)
*Manual mode (M)
Troubleshooting
If you have problems shifting gears or starting the engine, the automatic transmission selector position sensor may be faulty. Some common symptoms include:
* Difficulty shifting gears
* Inability to start the engine in park position
* Errors on the dashboard related to the position of the gear selector
Replacement
Replacing the automatic transmission selector position sensor is best done by a qualified mechanic. The replacement procedure may vary depending on the specific Kia Sorento model, but usually includes the following steps:
1. Removing the gear selector
2. Disconnecting electrical connectors from the sensor
3. Disconnecting the sensor from the gear selector housing
4. Installation of a new sensor
5. Assembling the gear selector and electrical connectors
