P1709 MERCURY Description
The Park/Neutral Position (PNP) Switch completes the start circuit in PARK and NEUTRAL, the back-up lamp circuit in REVERSE, and a neutral sense circuit. The sensor also opens/closes a set of four switches that are monitored by the Powertrain Control Module (PCM) to determine the position of the manual lever (P, R, N, (D), 2, 1). The Diagnostic Trouble Code (DTC) indicates that the voltage is high from the Park/Neutral Position Switch when it should be low.
