Code P1705 Description

The P1705 code indicates that the Transmission Range Sensor (TRS) is out of self-test range. The TRS is responsible for informing the vehicle's onboard computer of the gear position selected by the driver (Park, Reverse, Neutral, Drive, etc.). When the TRS is out of self-test range, it means that the signal being sent to the computer does not fall within the expected parameters. This can lead to issues with the transmission shifting correctly, causing erratic gear changes, harsh shifting, or even the transmission not shifting at all. If left unaddressed, it can potentially lead to more severe transmission problems and affect the overall drivability of the vehicle.
