Specifications

•
Indication on Axone always Normal, even when the sensor is inverted: disconnect the con-
nector and, with sensor inverted, check if there is continuity between the two PINS of the
sensor: if there is no continuity, replace the sensor; if there is, check the connector. If not
OK, restore the cable harness; if OK, check continuity to ground of PIN 2: if there is no
continuity, restore the cable harness; if there is, with key set to KEY ON, check if there is
12V voltage at PIN 1. If there is not, check the Marelli control unit connector (PIN 35 of the
BLUE connector)
•
Indication on Axone always Tip over: disconnect the connector and check if there is con-
tinuity between the two PINS when the sensor is in vertical position: if there is continuity,
replace the sensor; if there is not, it means that, with key set to KEY ON, there is no 12V
voltage at PIN 1: restore the cable harness whose pink/yellow cable will be shorted to ground
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 (cable harness side)
