Transmission Position Switch/Sensor: Description and Operation
This signal is sent from transmission control module as a battery voltage signal only when A/T is in "R", "D", "2" or "L" range. Thus, ECM judges
whether A/T is in one of the above range or otherwise (i.e. in "P" or "N" range) and uses it as one of the signals to control the fuel injector, idle speed
control valve and ignition control.
