Transmission Position Switch/Sensor: Description and Operation
Park/Neutral Position Signal (A/T Model Only)
Park/Neutral Position Signal (A/T model only)
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 air
control valve and ignition timing.
