Step
Check
Yes
No
1
CHECK ANY OTHER DTC ON DISPLAY.
Is any other DTC displayed?
Check DTC using
“List of Diagnostic
Trouble Code
(DTC)”. <Ref. to
EN(H4SO)(diag)-
70, List of Diag-
nostic Trouble
Code (DTC).>
NOTE:
In this case, it is
not necessary to
inspect
DTC
P0137.
Go to step

CHECK REAR OXYGEN SENSOR DATA.
1) Warm-up the engine until engine coolant
temperature is above 70°C (158°F), and keep
the engine speed at 3,000 rpm. (Max. 2 min-
utes)
2) Read the data of rear oxygen sensor signal
using Subaru Select Monitor or general scan
tool.
NOTE:
• For MT model, depress the clutch pedal.
• Subaru Select Monitor
For detailed operation procedure, refer to
“READ CURRENT DATA FOR ENGINE”. <Ref.
to EN(H4SO)(diag)-26, Subaru Select Moni-
tor.>
• General scan tool
For detailed operation procedure, refer to the
general scan tool operation manual.
Is the voltage 490 mV or
more?
Go to step

.
Go to step
3
.

CHECK REAR OXYGEN SENSOR CONNEC-
TOR AND COUPLING CONNECTOR.
Does water enter the connec-
tor?
Dry the water thor-
oughly.
Go to step
4
.
4
CHECK HARNESS BETWEEN ECM AND
REAR OXYGEN SENSOR CONNECTOR.
1) Turn the ignition switch to OFF.
2) Disconnect the connector from ECM and
rear oxygen sensor.
3) Measure the resistance of harness
between ECM and rear oxygen sensor con-
nector.
Connector & terminal
(B135) No. 4 — (E23) No. 3:
(B134) No. 29 — (E23) No. 4:
Is the resistance more than 3
Ω
?
Repair the open
circuit of harness
between ECM and
rear oxygen sen-
sor connector.
Go to step
5
.
5
CHECK HARNESS BETWEEN REAR OXY-
GEN SENSOR AND ECM CONNECTOR.
1) Turn the ignition switch to OFF.
2) Disconnect the connector from the rear
oxygen sensor.
3) Turn the ignition switch to ON.
4) Measure the voltage between rear oxygen
sensor harness connector and engine ground
or chassis ground.
Connector & terminal
(E23) No. 3 (+) — Engine ground (–):
Is the voltage 0.2 — 0.5 V?
Replace the rear
oxygen sensor.
<Ref. to
FU(H4SO)-34,
Rear Oxygen Sen-
sor.>
Repair the har-
ness and connec-
tor.
NOTE:
In this case, repair
the following item:
• Open circuit of
harness between
rear oxygen sen-
sor and ECM con-
nector
• Poor contact of
the rear oxygen
sensor connector
• Poor contact in
ECM connector
