Component Description
WARNING: This page is about a different car, the 2004 Infiniti I35. However, it is still accessible from the selected car via links, so may be relevant.
When the gear position is P or N, park/neutral position (PNP), switch is ON.
ECM detects the position because the continuity of the line (the ON signal) exists.
The park/neutral position (PNP) switch assembly also includes a transmission range switch to detect selector lever position.
