Component Description
WARNING: This page is about a different car, the 2012 Nissan Pathfinder. However, it is still accessible from the selected car via links, so may be relevant.
When the selector lever position is P or N, park/neutral position (PNP) signal is sent to ECM from TCM via combination meter (unified meter control unit).
ECM detects the position because the continuity of the line (the ON signal) exists.
