DTC Troubleshooting

1.
Was "A/T System Check" performed?
YES -
Go to Step 2.
NO -
Go to A/T System Check A/T System Check.

2. Check output shaft speed sensor circuit

Disconnect TCM connectors with ignition switch OFF.
Check for proper connection to output shaft speed sensor at "E93-5" and "E93-14" terminals.
If OK, check resistance of sensor circuit.

Resistance of output shaft speed sensor circuit
Between terminals "E93-5" and "E93-14" of disconnected harness side TCM connector: 560 - 680 ohms at 20 °C (68 °F)
Between terminals "E93-14" of disconnected harness side TCM connector and ground: No continuity

Are check results satisfactory?
YES -
Go to Step 4.
NO -
Go to Step 3.

3. Check output shaft speed sensor

Check output shaft speed sensor referring to Output Shaft Speed Sensor Inspection Output Shaft Speed Sensor Inspection.

Is check result satisfactory?
YES -
Output shaft speed sensor circuit is malfunction.
NO -
Go to Step 4.

4. Check visually output shaft speed sensor and sensor rotor using mirror for following

- No damage
- No foreign material attached
- Correct installation






Are they in good condition?
YES -
Intermittent trouble. Check for intermittent trouble referring to Intermittent and Poor Connection Inspection Intermittent and Poor Connection Inspection.
NO -
Clean, repair or replace.
