AIR TEMPERATURE SENSOR

To verify that the air temperature sensor works:

• Disconnect the two-way connector (1).

• Carry out the sensor check in an environment with

controlled temperature of 20 °C (68 °F).

• Measure the electrical resistance with an ohm

meter (scale 0-20 kΩ) between the connector

terminals (1).

Correct value: 12.200 k

Ω Ω

Ω - 12.700 k

If the air temperature sensor works correctly check the

dashboard:

• Apply a resistance equal to 12.4 kΩ between the

sensor terminals (cabling side).

• If the dashboard works correctly it should indicate

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