Code P1705 2008 Ford Fusion Description

The P1705 diagnostic trouble code (DTC) for a 2008 Ford Fusion indicates that the Transmission Range Sensor is out of self-test range. The Transmission Range Sensor, also known as the Neutral Safety Switch, is a crucial component of the vehicle's transmission system. It is responsible for detecting the position of the gear selector and informing the engine control module (ECM) about the gear selection. When the Transmission Range Sensor is out of self-test range, it means that the sensor's signal is not within the expected parameters during the self-test conducted by the ECM.
