5000S Wagon L5-2309cc 2.3L SOHC (NF) (1988)
The coolant temperature sensor consists of two NTC resistors within one housing. One resistor provides information on engine coolant
temperature to the ignition control unit. The second resistor provides the same information to the fuel injection control unit.
The signals from these sensors are used to provide corrections to the fuel mixture and ignition timing based on engine temperature.
Both resistors in the temperature sensor have the same resistance values. The sensor is located in the cylinder head coolant outlet flange.
