11. Angle Sensor Line Inspection 1
Disconnect the ECM 21P (Gray) connector and
the angle sensor 3P (Black) connector.
Check for continuity on the Black/red wire and
the Green/yellow wire between the ECM connec-
tor and main harness side angle sensor connec-
tor.
Is there continuity?
Open in wire between the ECM and the
NO
angle sensor
Faulty angle sensor After replace-
YES
ment, perform initial setting procedure
(page 24-6)
12. Angle Sensor Line Inspection 2
Disconnect the ECM 21P (Gray) connector and
the angle sensor 3P (Black) connector.

between the ECM connector and main harness
side angle sensor connector.
Is there continuity?
Open in wire between the ECM and the
NO
angle sensor
GO TO STEP 13.
YES
13. Angle Sensor Input Voltage Inspection
Turn the ignition switch ON.
