Component Description
WARNING: This page is about a different car, the 2004 Nissan Sentra. However, it is still accessible from the selected car via links, so may be relevant.
When the gear position is P or N (A/T models), park/neutral position (PNP) switch is ON.
ECM detects the park/neutral position when continuity with ground exists.
For A/T models, the park/neutral position (PNP) switch assembly also indicates a transmission range switch to detect selector lever position.
