There a a few different ways to tell when a sensor is bad. One way on some sensors, such as temp sensors (or thermistors) is to measure resistance at difference temps to confirm that it is reading correctly, you would have to have the known values for the sensor to compare it to though. Otherwise, you would need diagnostic tools to monitor the sensors while the vehicle is running to know if they are out of range.
