DTC Troubleshooting
Step
1 Was "A/T System Check" performed?
2 Check output shaft speed sensor power circuit
1) Turn ignition switch OFF.
2) Disconnect output shaft speed sensor connector.
3) Turn ignition switch ON.
4) Measure voltage between "BLK/RED" wire terminal of
disconnected output shaft speed sensor harness side
connector and ground.
Is it 10 – 14 V?
3 Check output shaft speed sensor ground circuit
1) Turn ignition switch OFF.
2) Check continuity between "BLK/ORN" wire terminal of
disconnected output shaft speed sensor harness side
connector and ground.
Is continuity indicated?
4 Check output shaft speed sensor signal circuit for short
1) Disconnect TCM connectors.
2) Check continuity between "PPL" wire terminal of
disconnected output shaft speed sensor harness side
connector and ground.
Is continuity indicated?
5 Check output shaft speed sensor signal circuit for open
1) Check continuity between "PPL" wire terminal of
disconnected output shaft speed sensor harness side
connector and terminal "C35-25" of disconnected
harness side TCM connector.
Is continuity indicated?
6 Inspect output shaft speed sensor
1) Inspect output shaft speed sensor referring to "Output
Shaft Speed Sensor Inspection".
Is check result satisfactory?
7 Check output shaft speed sensor gears visually
1) Check output shaft speed sensor gears for the

• No damage in drive gear on differential case
• No damage in driven gear in output shaft speed
sensor
Is result satisfactory?
