Inspection
-
Inspect the suction control valve.
-
Measure the resistance of the valve.
Standard resistance:
Tester Connection Condition Specified Condition 1 - 2 20°C (68°F) 1.9 to 2.3 ? HINT:
The temperature indicated in "Condition" is the temperature of the suction control valve.
If the result is not as specified, replace the supply pump assembly. -
-
Inspect the fuel temperature sensor.
-
Measure the resistance of the sensor.
-
Standard resistance:
Tester Connection | Condition | Specified Condition |
1 - 2 | 20°C (68 °F) | 2.32 to 2.59 ? |
1 - 2 | 80°C (176 °F) | 0.310 to 0.326 ? |
If the result is not as specified, replace the supply pump assembly.

Installation
-
Install a new O-ring to the supply pump.
-
Install the supply pump drive coupling.
NOTICE:
When reusing the coupling, it must be installed in the same orientation (top/bottom, front/back) as when it was removed,
HINT:
Line up the coupling with the groove in the camshaft end.
-
Install the supply pump with the 2 bolts.
Torque:
20.5 N*m{ 209 kgf*cm , 15 ft.*lbf }
NOTICE:
Apply engine oil on the O-ring of the supply pump.
HINT:
Line up the end of the supply pump drive shaft with the supply pump drive coupling.
-
Connect the suction control valve connector.
-
Connect the fuel temperature sensor connector.
NOTICE:
In a case where the supply pump is replaced, the fuel inlet pipe must also be replaced.
-
Temporarily install the fuel inlet pipe with the 2 clamps and nut.
-
Using SST, first tighten the nut at the common rail end of the fuel inlet pipe.
SST:
09023-38401
Torque:
27 N*m{ 275 kgf*cm , 20 ft.*lbf }
HINT:
- Use of the proper SST is required to ensure that the correct torque is applied to the inlet pipe nut.
- Use a torque wrench with a fulcrum length of 30 cm (11.81 in.).
- Make sure that the pipe is not deformed or twisted during installation.
- If the pipe is deformed or twisted, or if it cannot be installed properly, replace the pipe with a new pipe.
-
