Intake air temperature sensor (IAT) Hyundai Getz is built into the MAP absolute pressure sensor and is a thermistor whose resistance changes with temperature. The ECM takes into account the sensor signal and adjusts the pulse width applied to the injectors, resulting in a change in the amount of fuel supplied to the engine cylinders.
Sensor test
1. Measure the resistance between terminals 3 and 4 of the sensor connector.
Temperature | Resistance |
0°C | 4.5-7.5 kΩ |
20°C | 2.0-3.0 kΩ |
40°С | 0.7-1.6 kΩ |
80°С | 0.2–0.4 kΩ |
2. If the sensor resistance is out of specification, replace the sensor.
