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