FUEL INJECTION (FUEL SYSTEMS)(H4DOTC DIESEL) > Commonrail Assembly

INSPECTION

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

2. PRESSURE LIMITER

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.

3. OTHER INSPECTIONS

1. Check the common rail assembly for deformation, cracks and damage.

2. Check there is no fuel leakage from the connection of fuel pipe.
