    Q:
    How does the Coolant Temperature Sensor's resistance change with temperature for the Honda CRX? Posted by Louise D.
    A:
    First of all, note that the sensor uses a thermistor which is a temperature dependent diode that detects changes in coolant temperature. Also, the basic firing duration is calculated from these signals that are transmitted via this sensor to the ECU. Moreover, one should note that increase in coolant temperature brings down resistance of the thermistor.
