Disconnect the intake air temperature sensor
connector. Measure the resistance across the
sensor terminals.
Make sure that the resistance matches the stated
values with respect to the temperature.

Replace the sensor.
Connect the sensor connector and repeat the resistive check across PIN 18 and PIN 22.
PIN 18 - PIN 22 = the resistance matches the value read directly by the sensor.
In case that slightly higher
resistance values are measured,
check the connectors.
In case of infinitive resistance
(>1M
Ω
), check the continuity of the
two lines with the connectors
central unit and the intake
sensor disconnected.
