Coolant thermistor (15)
Location: on head "2" (16) (rear cylinder).
The temperature sensor detects the coolant tempera-
ture and is required to correct the injection time. The in-
jection time is increased if the coolant has not yet
reached the working temperature.
Atmospheric pressure sensor
Location: inside the engine control unit (5).
The intake pressure measured by the sensor is con-
verted into a voltage signal and is required by the en-
gine control unit to correct the injection time.
Air thermistor
Location: in the intake pipe of the left-hand air convey-
or.
The resistance measured by the thermistor is convert-
ed into a voltage signal and is required by the engine
control unit to correct the injection time.
