Neutral Safety Switch: Description and Operation
PNP SWITCH
Component Description
When the selector lever position is P or N (A/T), Neutral (M/T), park/neutral position (PNP) switch is ON.
ECM detects the position because the continuity of the line (the ON signal) exists.
Then the TCM sends the PNP switch signal to the ECM via combination meter. (A/T models)
