AIR TEMPERATURE SENSOR

To check the working state of the air temperature

sensor, proceed as follows:

• Disconnect the two-way connector (1).

• Check the sensor in an environment with a con-

trolled temperature of 68 °F (20 °C).

• Use an ohmmeter (scale 0-20 kΩ) to measure

electrical resistance between the terminals of the

connector (1).

Correct value: 12.200 k

Ω Ω

Ω - 12.700 k

If the air temperature sensor is operating correctly,

check the dashboard:

• Apply a resistance of 12.4 kΩ between the sensor

terminals (cabling side).

• If the dashboard is operating correctly, it should

show a temperature of 68 ± 3 °F (20 ± 1 °C).
