Electrical system
Air temperature sensor
Function
indicates to the control unit the temperature of the
intake air, used to calculate the oxygen, to opti-
mise the required fuel quantity for the correct com-
bustion
Operation / Operating principle
NTC type sensor (resistance sensor, inversely
variable with temperature)
Level in the electrical circuit diagram:
Temperature sensors
Position:
•
sensor: on the rear side of the filter
housing
•
connector: on the sensor
Electrical specifications:Resistance
•
at 0 °C (32 °F): 32.5 kΩ ± 5%
•
at 25 °C (77 °F): 10.0 kΩ ± 5%
Pin out:
1. 0-5 V signal
2. Ground
DIAGNOSTIC TOOL:PARAMETERS
Air temperature
Example value with key ON: 26 °C (78.8 °F):
This is one of the values set by the ECU in the
event of recovery mode
Air temperature before Recovery
Example value with key ON: -40 °C (-40.0 °F):
Value determined from the signal read without tak-
ing into consideration the recovery mode: the il-
lustrative value refers to an open circuit
