Power Trunk / Liftgate Hazard Sensor: Description and Operation
Pinch Sensor - Description
DESCRIPTION
Vehicles equipped with a power liftgate system utilize two pinch sensors (1). One pinch sensor is located on each side of the liftgate. These sensors look
like weather-strips, however they consist of pieces of electrically conductive rubber (tapeswitch), wires (2), resistor, double sided tape, and a plastic
carrier. The right side pinch sensor contains a thermistor that is integral to the pinch sensor assembly. The thermistor is a temperature sensor used by the
power liftgate control module to enable proper liftgate operation in extreme climate conditions. Pinch sensors are used to provide additional protection
against vehicle damage or personal injury caused by an obstacle being "pinched" between the liftgate and the liftgate opening of the vehicle.
The pinch sensors are wired in series with the power liftgate control module. If one pinch sensor becomes defective the module will act as though both
sensors are defective. The power liftgate latch "Cinching" operation will be disabled if a problem is detected by the control module.
