| Intake air temperature sensor, location | 
On engine 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. |
