Transmission Position Sensor/Switch: Description and Operation

PURPOSE/OPERATION
When the ignition switch is set ST position, the battery voltage is applied through the ignition switch and transaxle range switch to the ECM. If the selector lever is not P or N position, the battery voltage will not reach to the ECM. Based on this signal, the ECM determines the automatic transaxle load and drives the ISO motor to maintain optimum idle speed.
