Code P1709 2007 Ford Fusion Description

The P1709 diagnostic trouble code (DTC) for a 2007 Ford Fusion indicates that the Park/Neutral Position (PNP) switch is out of the self-test range. The PNP switch, also known as the transmission range sensor, is responsible for detecting the gear position of the transmission, specifically whether the vehicle is in Park or Neutral. When the PNP switch is out of the self-test range, it means that the signal being sent by the switch does not match the expected values during the self-test conducted by the vehicle's onboard computer.
