CHECK CURRENT DATA.
1) Turn the ignition switch to ON (engine OFF).
2) Using the Subaru Select Monitor, read the
values in «Sec. Air Piping Pressure», «Mani.
Absolute Pressure» and «Atmosphere Pres-
sure», and compare them with actual atmo-
spheric pressure.

Does the displayed value differ
from the actual atmospheric
pressure by 200 mmHg (27
kPa, 8 inHg, 3.9 psig) or more?
Even if DTC is

duce the failure,
and then perform
the diagnosis
again.
NOTE:
In this case, tem-
porary poor con-
tact of connector,
temporary open or
short circuit of har-
ness may be the
cause.
