Pin-out:
•
PIN 1: Ground connection
•
PIN 2: 0-5 V signal
AXONE: PARAMETERS
Air temperature
In case of failure, 25°C is set as 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
the sensor; if it is not OK, replace the sensor; if it is OK, check continuity between PIN 14
of the BROWN connector and PIN 2 of sensor: restore cable harness if there is not continuity;
if it is OK, reconnect the control unit connector and, with key set to key ON, check the
continuity between the sensor connector PIN 1 and the vehicle ground connection: if there
is not continuity, restore the cable harness; if there is continuity, it means that the cause of
the error is that the cable is shorted to positive and now the cable harness between the
BROWN PIN 14 and PIN 2 of the sensor should be restored. If the engine temperature
sensor error is displayed at the same time, this means that the grey cable common for both
sensors is shorted to positive.
•
If shorted to negative, check sensor correct resistance: if resistance = 0, replace the sensor;
if resistance is correct, it means that the pink/black cable has ground connection: restore
the cable harness
NOTES No error is detected if the sensor does not work correctly or the control unit connector
or sensor terminals are rusty: then check through Axone if the temperature indicated is plausible
in relation to the ambient temperature. Check also that the sensor electrical characteristics are
observed: replace the sensor if not OK; if it is OK, check the sensor connector and the Marelli
control unit connector
