Air temperature sensor
Function
It tells the control unit the intake air temperature in
order to calculate oxygen presence so as to opti-
mise the petrol quantity necessary for correct com-
bustion.
Operation / Operating principle
NTC type sensor (resistance sensor, inversely
variable with temperature).

AXONE: ELECTRICAL ERRORS
Air temperature sensor P0110
- Open circuit, shorted to positive / shorted to negative
Error cause
•
If the circuit is open, shorted to positive: excessive voltage has been detected at PIN 14 of
the BROWN connector.
•
If shorted to negative: voltage equal to zero has been detected at PIN 14 of the BROWN
connector
Troubleshooting
•
If the circuit is open, shorted to positive: check the sensor connector and the Marelli control
unit connector. If they are not OK, restore the cable harness; if OK, check the continuity of
