DTC DETECTING CONDITION:
•Detected when two consecutive driving cycles with fault occur.
•GENERAL DESCRIPTION
TROUBLE SYMPTOM:
•Engine stalls.
•Erroneous idling
CAUTION:
After repair or replacement of faulty parts, perform Clear Memory Mode
Step Check Yes No

2CHECK CURRENT DATA.
1) Start the engine and let it idle.
2) Measure the AVCS system operating angle
and oil flow control solenoid valve duty output
using Subaru Select Monitor or general scan
tool.
NOTE:•Subaru Select Monitor
For detailed operation procedures, refer to
“READ CURRENT DATA FOR ENGINE”.

•General scan tool
For detailed operation procedure, refer to the
general scan tool operation manual.
Is the AVCS system operating
angle approx. 0 deg., and oil
flow control solenoid valve duty
output approx. 10%?
Check the follow-
ing item and repair
or replace if nec-
essary.
•Oil pipe (clog)
•Oil flow con-
trol solenoid
valve (clog or
dirt of oil rout-
ing, setting of
spring, clog of
valve)

Fuel System Trouble in General
FUEL INJECTION (FUEL SYSTEMS)
29.Fuel System Trouble in General
A: INSPECTION
NOTE:
•When the vehicle is left unattended for an extended period of time, water may accumulate in the fuel tank.
Fill fuel fully to prevent those problem. And also drain water from fuel filter.
•In snow-covered areas, mountainous areas, skiing areas, etc. where ambient temperatures drop below
0°C (32°F) throughout the winter season, use a water removing agent in the fuel system to prevent freezing
fuel system and accumulating water. Fill the water removing agent at the time when the fuel reduced at half
to maintain the advantage.
•When water is accumulated in fuel filter, drain water from both the fuel filter and fuel tank or use water re-
moving agent in the fuel tank.
•Before using water removing agent, follow the cautions noted on the bottle.
