DTC Detecting Condition and Trouble Area
DTC Confirmation Procedure
1) Connect scan tool to DLC with ignition switch OFF.
2) Clear DTCs in TCM and ECM memories by using scan tool.
3) Start engine.
4) Start vehicle and increase vehicle speed to about 40 km/h (25 mile/h) for 20 minutes or more.
5) Stop vehicle.
6) Check DTC, pending DTC and freeze-frame data.
DTC Troubleshooting
DTC Detecting Condition Trouble Area
Transmission temperature sensor terminal voltage is less than
4.89 V under vehicle condition shown in the following.
• Ignition switch is turned on for 15 minutes or more
• Engine coolant temperature is more than 50 °C (122 °F)
(1 driving cycle detection logic)
• Transmission fluid temperature sensor or its
circuit.
•TCM
Step Action Yes No
1 Was “A/T System Check” performed? Go to Step 2. Go to “A/T System
Check: ”.
2 Check transmission fluid temperature sensor circuit for
open
1) Turn ignition switch OFF.
2) Disconnect TCM connectors from TCM.
3) Check for proper connection to transmission fluid
temperature sensor at terminal “E92-11” and “E92-12”.
4) If OK, check continuity between terminal “E92-11” and
“E92-12” of disconnected harness side TCM connector.
Is continuity indicated?
Go to Step 3. Transmission fluid
temperature sensor
circuit is open circuit.
3 Check transmission fluid temperature sensor circuit for
power supply short
1) Cool down A/T fluid temperature under ambient
temperature.
2) Connect TCM connectors to TCM with ignition switch
OFF.
3) Turn ignition switch ON.
4) Measure voltage between terminal “E92-11” of TCM
connector and ground.
Is it 4.89 V or more?
Transmission fluid
temperature sensor
circuit is shorted to
power supply circuit. If
circuit is OK, go to Step
4.
Intermittent trouble or
faulty TCM. Check for
intermittent trouble
referring to “Intermittent
and Poor Connection
Inspection: in Section
00”. If OK, substitute a
known-good TCM and
recheck.
4 Inspection transmission fluid temperature sensor
1) Inspection transmission fluid temperature sensor
referring to “Transmission Fluid Temperature Sensor
Inspection: ”.
Is result satisfactory?
Intermittent trouble or
faulty TCM. Check for
intermittent trouble
referring to “Intermittent
and Poor Connection
Inspection: in Section
00”. If OK, substitute a
known-good TCM and
recheck.
Replace valve body
harness including
transmission fluid
temperature sensor
referring to
“Transmission Fluid
Temperature Sensor
Removal and
Installation: ”.
