2. Signal - Pink/White colour, from VEHICLE
PIN 65 to the fall sensor, passing through
multiple connector - Section 0.5
3. Ground - Green/Pink colour, from ENGINE
PIN6/PIN17 to the fall sensor, passing
through multiple connector - Section 0.5
Air temperature sensor - instrument panel
Function
Indicates the ambient air temperature to the in-
strument panel.
Operation / Operating principle
NTC type sensor (resistance sensor, inversely
variable with temperature).

DIAGNOSTIC TOOL: PARAMETERS
Troubleshooting:
•
Check the sensor connector and the instrument panel connector (PIN 5 and 34): if not ok,
restore; if ok, check the continuity of the pink cable between the sensor connector and PIN
5 of the instrument panel connector: if not ok, restore the wiring harness; if ok, check if the
sensor resistance is correct: if not ok, replace the sensor; if ok, check the continuity of the
blue/black cable between the sensor connector and PIN 34 of the instrument panel con-
nector: if not ok, restore the wiring harness; if ok, check (with key ON) the voltage at PIN 1
of the sensor connector: if there is no voltage, replace the instrument panel; if there is ap-
