There is a raised blob on the sensor and then the wiring harness connector has a flexible clip that goes over that blob. To remove put your finger at the end of the clip and raise it and pull the connector or push it off with the finger raising the clip. It is just a simple clip going over the blob. In the picture my finger is on the nut of the sensor and the clip you raise is just to the right.
