Inspection
-
Inspect the fuel pressure sensor.
-
Measure the resistance of the sensor.
HINT:
Perform the inspection with no fuel pressure applied.
Standard resistance:
If the result is not as specified, replace the common rail assembly.Tester Connection Specified Condition 5 (PR) - 4 (E2) 16.4 k? or less 2 (PR2) - 3 (E2S) 16.4 k? or less 6 (VC) - 5 (PR) 3 k? or less 1 (VCS) - 2 (PR2) 3 k? or less
-
-
Inspect the pressure discharge valve.
-
Measure the resistance of the valve.
Standard resistance:
Tester Connection Condition Specified Condition 1 - 2 20°C (68°F) 0.85 to 1.05 ? HINT:
The temperature indicated in "Condition" is the temperature of the pressure discharge valve.
If the result is not as specified, replace the common rail assembly.

Installation
-
Install the intake manifold insulator and common rail with the 2 bolts.
Torque:
20.5 N*m{ 209 kgf*cm , 15 ft.*lbf }
-
Using pliers, grip the claws of the clip and slide the clip to connect the fuel hose as shown in the illustration.
NOTICE:
In a case where the common rail is replaced, the injection pipes must also be replaced.
-
Temporarily install the 4 injection pipes.
-
Using SST, tighten the 4 nuts at the common rail end of the injection pipes.
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 injection 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.
