1) Start the engine.
2) Read the data of intake manifold absolute

EN(H6DO)(diag)-137
Diagnostic Procedure with Diagnostic Trouble Code (DTC)
ENGINE (DIAGNOSTICS)
Step Check Yes No
1CHECK CURRENT DATA.
1) Start the engine.
2) Read the data of intake manifold absolute
pressure signal using Subaru Select Monitor or
general scan tool.
NOTE:
•Subaru Select Monitor
For detailed operation procedures, refer to
“READ CURRENT DATA FOR ENGINE”. to EN(H6DO)(diag)-26, Subaru Select Moni-
tor.>
•General scan tool
For detailed operation procedure, refer to the
general scan tool operation manual.
Is the measured value less
than 13.3 kPa (100 mmHg,
3.94 inHg) ?
Go to step 3.Go to step 2.
2CHECK POOR CONTACT.
Check the poor contact in ECM and manifold
absolute pressure sensor connector.
Is there poor contact in ECM or
manifold absolute pressure
sensor connector?
Repair the poor
contact in ECM or
manifold absolute
pressure sensor
connector.
Even if the mal-
function indicator
light illuminates,
the circuit has
returned to a nor-
mal condition at
this time.
3CHECK OUTPUT SIGNAL OF ECM.
Measure the voltage between ECM connector
and chassis ground.
Connector & terminal
(B134) No. 19 (+) — Chassis ground (–):
Is the voltage more than 4.5 V? Go to step 5.Go to step 4.
4CHECK OUTPUT SIGNAL OF ECM.
Measure the voltage between ECM connector
and chassis ground.
Connector & terminal
(B134) No. 19 (+) — Chassis ground (–):
Does the voltage change by
shaking the ECM harness and
connector?
Repair poor con-
tact in ECM con-
nector.
Replace the ECM.
FU(H6DO)-32,
Engine Control
Module (ECM).>
5CHECK INPUT SIGNAL OF ECM.
Measure the voltage between ECM and chas-
sis ground.
Connector & terminal
(B134) No. 6 (+) — Chassis ground (–):
Is the voltage less than 0.2 V? Go to step 7.Go to step 6.
6CHECK INPUT SIGNAL FOR ECM (USING
SUBARU SELECT MONITOR).
Read the data of atmospheric absolute pres-
sure signal using Subaru Select Monitor.
NOTE:For detailed operation procedures, refer to
“READ CURRENT DATA FOR ENGINE”. to EN(H6DO)(diag)-26, Subaru Select Moni-
tor.>
Is the measured value more
than 13.3 kPa (100 mmHg,
3.94 inHg) when shaking the
ECM harness and connector?
Repair poor con-
tact in ECM con-
nector.
Go to step 7.
7CHECK HARNESS BETWEEN ECM AND
MANIFOLD ABSOLUTE PRESSURE SEN-
SOR CONNECTOR.
1) Turn the ignition switch to OFF.
2) Disconnect the connector from manifold
absolute pressure sensor.
3) Turn the ignition switch to ON.
4) Measure the voltage between manifold
absolute pressure sensor connector and
engine ground.
Connector & terminal
(E28) No. 3 (+) — Engine ground (–):
Is the voltage more than 4.5 V? Go to step 8.Repair the open
circuit of harness
between ECM and
manifold absolute
pressure sensor
connector.
