P1119 NISSAN Meaning

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

P111D Meaning

The Fuel Temperature Sensor 2 and Intake Air Temperature (IAT) Sensor 1 are variable resistors. The Fuel Temperature Sensor 2 is located on the fuel rail and the IAT Sensor 1 is part of the Mass Air Flow/Intake Air Temperature (MAF/IAT) sensor assembly. The Engine Control Module (ECM) provides 5V to the signal circuits and a ground for the low reference circuit of each sensor. The ECM monitors the Fuel Temperature Sensor 2 and IAT Sensor 1 circuits to calculate fuel and air temperature. The ECM monitors the Fuel Temperature Sensor 2 and IAT Sensor 1 signals for excessively high or low voltages, or for voltage that doesn’t correlate with the other sensor’s startup signal.
