Transmission Position Switch/Sensor: Description and Operation
Operation
Park/Neutral Contact
PARK/NEUTRAL CONTACT
In selector lever positions "P" and "N" the park/neutral contact (4) is actuated by a cam track which is located on the detent plate. The permanent magnet
(3) is moved away from the dry-reed contact (4). The dry-reed contact (4) is opened. The TCM receives an electric signal. The circuit to the starter in the
selector lever positions "P" and "N" is closed.
Transmission Temperature Sensor
TRANSMISSION TEMPERATURE SENSOR
The temperature of the transmission oil has a considerable effect on the shifting time and therefore the shift quality. By measuring the oil temperature,
shift operations can be optimized in all temperature ranges. The transmission oil temperature sensor (1) is switched in series with the park/neutral
contact. The temperature signal is transferred to the TCM only when the dry-reed contact of the park/neutral contact is closed in REVERSE or a forward
gear position.
