Stelvio 1200 NTX ABS
Air temperature sensor - instrument panel
Function
It tells the ambient air temperature to the instru-
ment panel.
Operation / Operating principle
NTC type sensor (resistance sensor, inversely
variable with temperature).
Level in wiring diagram:Temperature sensors
Location:
•
Sensor: under the instrument panel
•
Connector: under the instrument panel
Electrical characteristics:
•
Resistance at 0°C: 32.5 kOhm +/- 5%
•
Resistance at 25°C: 10.0 kOhm +/- 5%
Pin-out:
1. Voltage 5V
2. Ground connection
Instrument panel
Air temperature sensor failure DSB 06
Error cause
•
An oil sensor failure is signalled when it is detected that the sensor circuit is open or shorted
to positive
Troubleshooting
•
Check the sensor connector and the instrument panel connector (PINS 10 and 18): If they
are not OK, restore. If OK, check continuity of the pink cable between the sensor connector
and the instrument panel connector PIN 10: if it is not OK, restore the cable harness; if OK,
check the correct sensor resistance: if it is not OK, replace the sensor; if it is OK, check
continuity of the brown cable between the sensor connector and PIN 18 of the instrument
panel connector: If not OK, restore the cable harness; if OK, with key set to ON, check if
there is voltage at the sensor connector PIN 1: if there is no voltage, replace the instrument
panel; if there is approximately 12V, restore the cable harness (there is a short circuit in the
battery). If there is 5V voltage, connect a 10 kOhm resistance to PIN 1 of the sensor con-
nector and to the vehicle ground connection: if, with key set to KEY ON, the voltage
measured upstream the resistance decreases, replace the instrument panel. If voltage con-
tinues to be approximately 5V, restore the pink cable (there is a short circuit at + 5V).
