Coolant Temperature Sensor/Switch (For Computer): Description and Operation

    The coolant temperature sensor is a thermistor which relays engine coolant temperature information to the ECM micro processor. This temperature
information is used to determine when the system is ready to enter the closed loop mode of operation. The information from this sensor is also used to
modify the open loop duty cycle.
