Circuit Description
When the shift lever is in the N or P position: 1) the Park/Neutral Position (PNP) switch turns on, and 2) ECM terminal NSW is grounded to the body ground via the starter relay and voltage becomes 0 V. When the shift lever is in the D, 2, L or R position: 1) the PNP switch turns off, and 2) ECM terminal NSW receives current and becomes the voltage of the ECM internal power source.
If the shift lever is moved from the N position to the D position, this signal is used for air-fuel ratio correction and for idle speed control (estimated control), etc.
