Mitsubishi automatic transmission shift sensor
The Mitsubishi automatic transmission shift sensor is used to detect the position of the gear selector and transmit this information to the electronic transmission control unit (TCU). The TCU uses this information to control torque converter lock-up, gear shifting, and other transmission-related systems.
Placement and operating principle
The gear shift sensor is usually located near the gear selector. It consists of an electrical connector, a wiring harness and an internal switch.
As the driver moves the gear selector to different positions, a switch inside the sensor switches contacts that correspond to the specific gear position. The gear position information is then transmitted to the TCU via the wiring harness.
Types of Gear Shift Sensors
Mitsubishi automatic transmissions use various types of shift sensors, including:
*Linear Variable Differential Transformer (LVDT) sensors: These sensors use an electromagnet to measure the position of a sliding rod that is connected to the gear selector.
* Hall Effect Sensors: These sensors use magnets and the Hall effect to detect the position of the gear selector.
*Microswitch sensors: These sensors use a series of microswitches to detect the position of the gear selector.
Common problems
Common problems associated with Mitsubishi automatic transmission shift sensors include:
* Incorrect gear position detection
* Difficulty shifting gears
*Transmission errors
* Damage to wiring harness
Diagnostics and replacement
Diagnosis of a faulty gear shift sensor can be done using a diagnostic scanner. If the sensor is faulty, it must be replaced. Replacing the shift sensor is a relatively simple procedure that can be performed by a qualified mechanic.
Prevention measures
To prevent problems with the Mitsubishi automatic transmission gear shift sensor, it is recommended:
* Regularly check the level and condition of the transmission fluid.
* Avoid sudden gear changes.
* Replace transmission fluid and filter at intervals specified by the manufacturer.
