Electrical system
Engine temperature sensor
Function
It is used to indicate to the control unit the engine
temperature, to optimise it behaviour and to cal-
culate the engine friction for a better estimation of
the to the delivered torque.
Operation / Operating principle
NTC type sensor (resistance sensor, inversely
variable with temperature).
Level in electrical circuit diagram:
Temperature sensors
Position:
•
on the vehicle: on the right side, next to
the two big ends.
•
connector: on the sensor.
Electrical specifications:
•
Resistance at 25°: 2.05 kΩ ± 100/Ω
•
Resistance at 60°: 575 Ω ± 15 /Ω
•
Resistance at 90°: 230 Ω ± 5 /Ω

DIAGNOSTIC TOOL: PARAMETERS
Engine temperature:
•
Example value with key ON: 25° C
•
Example value with engine on: 75° C
•
This is one of the values set by the ECU in the event of recovery mode: if there is a mal-
function after the engine start-up, the temperature is raised up to approximately 75°.
Engine temperature before Recovery:
•
Example value with key ON: -40° C
•
Example value with engine on: -40° C
•
Value determined from the signal read without taking into consideration the recovery mode:
the illustrative value refers to an open circuit.
Engine temperature at start-up:
