Transmission Position Switch/Sensor: Description and Operation
Neutral Gear Switch (NGS)
Neutral Gear Switch (NGS)
PURPOSE
The Neutral Gear Switch (NGS) detects when the manual transaxle is in the in-gear or neutral position and sends an input signal to the ECA. This
is an engine load input used by the ECA in calculations for adjusting idle speed, air/fuel mixture, fuel pressure, and purge flow.
OPERATION
NGS is an ON/OFF switch that receives a 5 Volts reference from the ECA. When the switch is OPEN (transmission in GEAR), the ECA senses
voltage. When the switch is CLOSED (vehicle in NEUTRAL), the ECA senses no voltage.
