Wiring Diagram
1. Transmission fluid temperature sensor
2. TCM
DTC Detecting Condition and Trouble Area
DTC Detecting Condition
Transmission temperature sensor terminal voltage is less than
0.05 V for 10 seconds or more after ignition switch ON.
(1 driving cycle detection logic)
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) Keep engine running at idle speed for 1 minute or more.
5) Check DTC, pending DTC and freeze-frame data.
DTC Troubleshooting
Step
1 Was "A/T System Check" performed?
2 Check transmission fluid temperature sensor A circuit
for ground short
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" of
disconnected harness side TCM connector and ground.
Is continuity indicated?
3 Inspection transmission fluid temperature sensor
1) Inspection transmission fluid temperature sensor
referring to "Transmission Fluid Temperature Sensor
Inspection: ".
Is result satisfactory?

Yes
Go to Step 2.
Transmission fluid
temperature sensor
circuit is shorted to
ground. If circuit is OK,
go to Step 3.
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.
