P1119 Infiniti Description

The radiator coolant temperature sensor is installed on the radiator lower tank and used to detect the radiator coolant temperature. The sensor modifies a voltage signal from the Engine Control Module (ECM) and returns the modified signal to the ECM as the radiator coolant temperature input. The sensor uses a thermistor which is sensitive to the change in temperature. The electrical resistance of thermistor decreases as temperature increase. The ECM uses this signal to control the cooling fan speed control solenoid valve.
