Neutral Safety Switch: Description and Operation

PNP SWITCH

Component Description
When the shift position is P or N (A/T models), Neutral (M/T models), park/neutral position (PNP) switch is turned ON.

ECM detects the position because the continuity of the line (the ON signal) exists.

For A/T models, the park/neutral position (PNP) switch assembly also indicates a transmission range switch to detect selector lever position.
