SENSORS

Neutral sensor
To check this sensor, the circuit should be checked between the terminal and earth.
With the gearbox in neutral, it should register 0
Ω
∞
On selecting a gear the meter should register (Infinity).
Checking the diode
VI VI BLK
6. Ambient temperature sensor.
7. Carburettor thermal resistance.
Checking the ambient temperature sensor
Check the resistance with the meter between the ends of the sensor - under
11° C +/- 3 the resistance value is 0
Ω.
When the temperature rises, it should switch off at 16° C, and the Ω value should
be infinity.
Checking the thermal resistance
To check whether the thermal resistance works properly, it should be connected to
a 12V battery and should warm up within a few seconds.
