1Was “A/T System Check” performed?Go to Step 2. Go to “A/T System
Check”.
2Inspect transmission fluid temperature sensor
1) Inspect transmission fluid temperature sensor referring
to “Transmission Fluid Temperature Sensor Inspection”.

3Check for transmission fluid temperature sensor circuit
1) Turn ignition switch to OFF position.
2) Disconnect valve body harness connector and TCM
connectors.
3) Check for proper connection to TCM at terminals “C06-
11” and “C06-12”. If connection is OK, check circuit for
open, short and high resistance for the following circuit.
• Between “C06-11” terminal of TCM connector and “LT
GRN” terminal of valve body harness connector.
• Between “C06-12” terminal of TCM connector and
“ORN” terminal of valve body harness connector.
Are they in good condition?Intermittent trouble or
faulty TCM. Check for
intermittent referring to

DTC Confirmation Procedure
WARNING!
• When performing a road test, select a place where there is no traffic or possibility of a traffic
accident and be very careful during testing to avoid occurrence of an accident.
• Road test should be carried out with 2 persons, a driver and a tester, on a level road.

1) Connect scan tool to DLC with ignition switch OFF, if available.
2) Clear DTC in TCM memory and start engine and keep for 20 minutes or more.
3) Stop vehicle and check DTC.
