1. Check the common rail assembly for deformation, cracks and damage.
2. Check that there is no fuel leakage from pipe joints.
1. COMMON RAIL PRESSURE SENSOR
Measure the resistance between all common rail pressure sensor terminals.
Standard:
|
Terminals |
Resistance |
|
1 — 2 |
Approx. 13.7 kΩ |
|
2 — 3 |
Approx. 2.5 kΩ |
1. Turn the ignition switch to OFF.
2. Connect the Subaru Select Monitor to the vehicle.
3. Start the engine and let it idle.
4. Perform “High Pressure Fuel Inspection” using “System Operation Check Mode”. 
If fuel pressure does not increase, check if the fuel pump has any fault, and if there is no fault, replace the common rail assembly.
