INSPECTING THE COMPONENTS
1.
INSPECTING THE SUCTION CONTROL VALVE AND THE
FUEL TEMPERATURE SENSOR
(1)
Using the HINO-DX, inspect the suction control valve and the fuel
temperature sensor. If any abnormality is found in either of the
parts, replace the supply pump. (Refer to the HINO-DX user's
manual.)
2.
INSPECTING THE RESISTANCE OF THE SUCTION CONTROL
VALVE
(1)
Using the circuit tester, measure the resistance between the ter-
minals. If the measured value is in excess of the standard value,
replace the supply pump.
3.
INSPECTING THE RESISTANCE OF THE FUEL TEMPERA-
TURE SENSOR
(1)
Using the circuit tester, measure the resistance between the ter-
minals. If the measured value is in excess of the standard value,
replace the supply pump.
