Description And Operation: Operation

During a power liftgate "close" cycle, if either of the two conductive rubber strips (tapeswitch) of the pinch sensor come in contact with an obstacle, the pinch sensor circuit is completed. This tells the power liftgate control module that an obstruction is felt. The control module will stop the liftgate immediately and return it to the full open position.

The thermistor portion of the right pinch sensor provides the temperature signal to the power liftgate control module (temperature is provided when the pinch sensor is in an unpinched condition; when pinched, temperature is unavailable because the thermistor is shorted). As the outside temperature increases, the resistance reading decreases. As temperature decreases, the resistance reading increases.
