CHECK PRESSURE SENSOR.
1) Measure actual atmospheric pressure.
2) Read data on Subaru Select Monitor or OBD-II general
scan tool.
Subaru Select Monitor
Designate mode using function key.
Function mode: F20
F20: Display shows pressure signal value sent from the
pressure sensor.
: Is the difference between absolute value of
Subaru Selector Monitor indication and
actual atmospheric pressure greater than 10
kPa (0.102 kg/cm
2, 1.45 psi)?
: Replace pressure sensor.
: Even if MIL lights up, the circuit has returned to a
normal condition at this time. Contact with SOA
service.
NOTE:
Inspection by DTM is required, because probable cause is
deterioration of multiple parts.

CHECK VACUUM HOSE.
: Is there a fault in vacuum hose?
NOTE:
Check the following item.
Incorrect hose connections in line between the pressure
sources switching solenoid valve and pressure sensor,
intake manifold and/or CPC solenoid valve.
: Repair or replace hoses or filter.
: Go to step10CJ4.

10CJ4CHECK PRESSURE SOURCES SWITCH-
ING SOLENOID VALVE.
1) Turn ignition switch to OFF.
2) Connect test mode connector.
3) Turn ignition switch to ON.
: Does pressure sources switching solenoid
valve produce operating sound? (ON↔
OFF each 1.5 sec.)
NOTE:
Pressure sources switching solenoid valve operation check
can also be executed using Subaru Select Monitor (Func-
tion mode: FD10). For the procedure, refer to“COMPUL-
SORY VALVE OPERATION CHECK MODE”.
[T3F0].>
: Replace pressure sensor.
: Replace pressure sources switching solenoid
valve.

CHECK DATA FOR CONTROL.
1) Turn ignition switch to OFF.
2) Connect Subaru Select Monitor or the OBD-II general
scan tool to data link connector.
3) Turn ignition switch ON and Subaru Select Monitor or
the OBD-II general scan tool switch ON.
4) Start engine.
5) Read data on Subaru Select Monitor or the OBD-II gen-
eral scan tool.

: Is the value more than 133 kPa in function
mode F20?
: Replace pressure sensor.
: Even if MIL lights up, the circuit has returned to a
normal condition at this time. Contact with SOA
service.
NOTE:
Inspection by DTM is required, because probable cause is
