5.2.23. Sensor of temperature of fuel (FTS)

As a basic element of the sensor of temperature of fuel the thermoresistor with negative temperature coefficient (NIC) which is a part of a contour of a divider of tension is used. As basic tension of 5 Century is used.

Power failure on the thermoresistor is transmitted to ESM through the analog-digital converter (ADC). According to the characteristic which is written down in memory, ESM determines temperature as function of tension.

Check of the sensor

You carry out an inspection of the sensor after turn of a key in the ignition lock in position of ON or START.
