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)
Level in wiring diagram:
Temperature sensors
Location:
•
sensor: on rear side of the filter box
•
connector: on the sensor
Electrical characteristics: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 connection
DIAGNOSIS INSTRUMENT: PARAMETERS
Air temperature
Example value with key ON: 26 °C (78.8 °F)
In case of recovery, this value is set by the control
unit
Air temperature pre Recovery
Example value with key ON: -40 °C (-40.0 °F)
Value drawn from the signal read without taking
into account any recovery: the value in the exam-
ple refers to an open circuit
