6CHECK HARNESS BETWEEN ECM AND
MASS AIR FLOW SENSOR CONNECTOR.
Measure the resistance of harness between
ECM and chassis ground.
Connector & terminal
(B135) No. 26 — Chassis ground:
(B135) No. 34 — Chassis ground:
(B135) No. 30 — Chassis ground:
Is the resistance more than 1
MΩ?
Go to step 7.Repair the ground
short circuit
between ECM and
mass air flow sen-
sor connector.
7CHECK POOR CONTACT.
Check poor contact of mass air flow sensor
connector.
Is there poor contact in mass
air flow sensor connector?
Repair the poor
contact of mass air
flow sensor con-
nector.
Replace the mass
air flow and intake
air temperature
sensor.

Step Check Yes No
1CONNECT SUBARU SELECT MONITOR OR
THE GENERAL SCAN TOOL, AND READ
DATA.
1) Turn the ignition switch to OFF.
2) Connect the Subaru Select Monitor or gen-
eral scan tool to data link connector.
3) Turn the ignition switch to ON, and the Sub-
aru Select Monitor power switch to ON.
4) Start the engine.
5) Read the voltage of mass air flow sensor
using Subaru Select Monitor or general scan
tool.
NOTE:•Subaru Select Monitor
For detailed operation procedures, refer to
“READ CURRENT DATA FOR ENGINE”.
tor.>
•General scan tool
For detailed operation procedure, refer to the
general scan tool operation manual.
Is the voltage 0.2 — 4.7 V? Even if the mal-
function indicator
light illuminates,
the circuit has
returned to a nor-
mal condition at
this time.
Go to step 2.
2CHECK HARNESS BETWEEN ECM AND
MASS AIR FLOW SENSOR CONNECTOR.
1) Turn the ignition switch to OFF.
2) Disconnect the connector from mass air-
flow sensor.
3) Turn the ignition switch to ON.
4) Measure the voltage between mass air flow
sensor connector and chassis ground.
Connector & terminal
(B3) No. 3 (+) — Chassis ground (–):
Is the voltage more than 5 V? Repair the battery
short circuit of har-
ness between
mass air flow sen-
sor connector and
ECM connector.
Go to step 3.
3CHECK HARNESS BETWEEN ECM AND
MASS AIR FLOW SENSOR CONNECTOR.
1) Turn the ignition switch to OFF.
2) Disconnect the connectors from ECM.
3) Measure the resistance of harness
between ECM connector and mass air flow
sensor connector.
Connector & terminal
(B3) No. 2 — (B135) No. 34:
Is the resistance less than 1
Ω?
Replace the mass
air flow sensor.
Mass Air Flow and
Intake Air Temper-
ature Sensor.>
Repair the open
circuit of harness
between mass air
flow sensor con-
nector and ECM
connector.
