DTC Troubleshooting
Step
1 Was "A/T System Check" performed?
2 Check Output Shaft Speed Sensor Circuit
1) Disconnect TCM connectors with ignition switch OFF.
2) Check for proper connection to output shaft speed
sensor at "G07-4" and "G07-16" terminals.
3) If OK, check resistance of sensor circuit. Resistance
between terminals "G07-4" and "G07-16" of
disconnected harness side TCM connector: 648 – 792 Ω
at 20 °C (68 °F) Resistance between terminal "G07-4" /
"G07-16" of disconnected harness side TCM connector
and ground: No continuity
Are check results satisfactory?
3 Inspect output shaft speed sensor
1) Inspect output shaft speed sensor referring to "Output
Shaft Speed Sensor Inspection".
Is result satisfactory?
4 Check visually output shaft speed sensor and sensor
rotor using mirror for the following
• No damage
• No foreign material attached
• Correct installation
Are they in good condition?
