EQUIPMENTS REQUIRED

•

3 ½ Digital Multi-meter (

DMM

)

•

Water Bath

•

Heating arrangement for boiling the water

Measurement Set-up showing the water level up to

which the sensor should be dipped.

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 wa-

ter 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 cool-

ing 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 entering

in the HP pump. The fuel temperature sensor

measures fuel temperature on the pump hydraulic

head in the low pressure circuit, between the transfer

pump outlet and the inlet to the HP pumping stage.

This sensor information issued to modify rail pres-

sure control, injection etc. This sensor is in built with

HP Pump.

DESCRIPTION

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).
