TEST PROCEDURE



Use a d 3-½ digit Digital Multi meter (

DMM

) for

measuring the resistance.



Immerse the sensor in a water bath such that its

terminals are facing upwards and out side the

water level. (

See fig.)



Ensure that, around 50% of the hexagonal

flange thickness should lie below the water. (

See

fig.)



Boil the water and wait for 10 minutes after boil-

ing temperature of 100 deg c is reached. This

will ensure that the temperature is stabilized.



Measure the resistance value with the DMM at

100 Deg C resistances of the sensor should be

199.6 +/- 9.3 Ohms.

REFITMENT

1. Fit the coolant temperature sensor on upper

cooling line.

2. Connect the wiring harness connector to the

coolant temperature sensor.

3. Fill the coolant.

4. Fit the engine cover.

6. FUEL TEMPERATURE SENSOR (

FTS

)

This sensor monitors the temperature of fuel enter-

ing in the HP pump. The fuel temperature sensor

measures fuel temperature on the pump hydraulic

head in the low pressure circuit, between the trans-

fer pump outlet and the inlet to the HP pumping

stage. This sensor information issued to modify rail

pressure control, injection etc. This sensor is in built

with HP Pump.

Fuel temperature signal

Fuel temperature return

INSPECTION:

1. Measure the resistance between the two Fuel

temperature sensor connector terminals; it should

be ~1814.2 ohms at 30 degrees (Consider 30 deg

as room temperature).
