| Intake air temperature sensor, location | Engine 104, 111 (HFM), Engine 119, 120 (ME1.0) On engine 104 ME, 111 ME, 112, 113,137 the intake air temperature sensor is integrated in the hot film mass air flow sensor. |
GF07.04-P-2100-01F | |
| Intake air temperature sensor, task | Records the inlet air temperature and sends a signal to the engine control unit. The signal is used for calculating the air mass. The amount injected and the point of ignition are influenced. | ||
| Intake air temperature sensor, design | Plastic housing with a NTC resistor, 2-pin plug connection | ||
| Intake air temperature sensor function | The NTC resistor integrated in the intake air temperature sensor, alters its electrical resistance in line with the intake air temperature. NTC means Negative Temperature Coefficient; which means that the electrical resistance drops as the temperature increases. |
