Air temperature sensor

Air temperature sensor (1310)

The air temperature sensor informs the ECU about the temperature of the air taken in .

Role of the injection ECU according to the data received :

To calculate the density of the ambient air

To work out the amount of fuel to inject


The air temperature probe is incorporated into the air flow meter (1310) .

The sensor consists of a Negative Temperature Coefficient (NTC) resistor .

The more the temperature increases, the more its resistance value is reduced .

Electrical specifications :

Resistance at 20 °C = 6250 ohms

Resistance at 80 °C = 600 ohms
