A system for detecting an obstacle between a closure panel and a body of a vehicle, comprising: an actuator for moving the closure panel from a partially closed position to a closed position; a sensor for sensing a position of the closure panel between the partially closed and the closed position; and a controller for receiving position signals from the sensor and for controlling operation of the actuator; wherein the controller is adapted to inhibit moving of the closure panel when the sensor detects an improper change in the position of the closure panel during operation of the actuator.
