A tester tool for a sensor and related method includes connecting the sensor to the tester tool, activating the tester tool to operate the sensor, and testing the sensor. The tester tool includes a power supply, a control module, a display module and a connector plug adapted for releasable connection with a sensor connector plug, the connector plug being connected to the power supply for receiving power to operate the sensor, and to the control module for providing information to the control module from the sensor. The display module provides information to a user indicative of operation of the sensor when the sensor is active and receives power to operate from the power supply.
