Pajero Sport automatic transmission selector sensor
The transmission shift sensor, also known as the transmission position switch, is an electronic component that tells the electronic transmission control unit (ETM) about the position of the transmission selector. This information is used by the computer to change gears correctly according to the selector lever position.
Location
On a Pajero Sport car, the automatic transmission selector sensor is usually located in the automatic transmission selector housing on the center console.
Function
When the automatic transmission selector is moved to another position, the automatic transmission selector sensor sends a corresponding electrical signal to the computer. The ECU uses this signal to:
* Determining the position of the automatic transmission selector
* Gear changes according to selector position
* Activation or deactivation of relevant automatic transmission functions, such as torque converter lock-up, sport mode or manual gear shift mode.
Possible faults
The main symptoms of a faulty automatic transmission selector sensor include:
* Incorrect or delayed gear shifting
* Errors or warning indicators related to automatic transmission
* Inability to switch the automatic transmission to a certain position
Replacement
Replacing the automatic transmission selector sensor may be necessary if it is faulty. Replacement usually involves the following steps:
1. Disconnecting the battery terminals
2. Removing the center console cover
3. Disconnecting the electrical connector of the automatic transmission selector sensor
4. Removing the automatic transmission selector sensor
5. Installation of a new automatic transmission selector sensor
6. Connecting the electrical connector of the automatic transmission selector sensor
7. Assembling the center console casing
8. Connecting battery terminals
Since replacing an automatic transmission shift sensor may require specialized tools and knowledge, it is recommended that you seek assistance from a qualified mechanic.
