Engine temperature sensor
Function
indicates the engine temperature to the control unit
so as to optimise carburetion and idle control
Operation / Operating principle
NTC type sensor (resistance sensor, inversely
variable with temperature).

NAVIGATOR: PARAMETERS
Engine temperature
In case of failure, the value read on Navigator (20°C - 68°F) is set by the control unit, so it is not a real
value.
NAVIGATOR: ELECTRICAL ERRORS
