DTC P0713: Transmission Fluid Temperature Sensor “A” Circuit HighS7RS0B5104026
Wiring Diagram
DTC Detecting Condition and Trouble Area 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 circuit for ground
short
1) Check continuity between terminal “C34-11” of
disconnected harness side TCM connector and ground.
Is continuity indicated? “LT GRN” circuit shorted
to ground.
Go to Step 3.
3 Inspect transmission fluid temperature sensor
1) Inspect transmission fluid temperature sensor referring
to “Transmission Fluid Temperature Sensor Inspection”.
Is result satisfactory? Intermittent trouble or
faulty TCM. Check for
intermittent referring to
“Intermittent and Poor
Connection Inspection
in Section 00”. If OK,
substitute a known-
good TCM and recheck.Replace transmission
fluid temperature
sensor.

DTC Detecting Condition and Trouble Area
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 ig nition switch OFF, if available.
2) Clear DTC in TCM memory and start engine.
3) Shift select lever to “D” range and drive vehicle at 50 km /h (31 mile/h) or more with 3rd gear at least for 5 minutes.
4) Stop vehicle and check DTC.

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.

3 Inspect input shaft speed sensor
1) Inspect input shaft speed sensor referring to “Input Shaft
Speed Sensor Inspection”.
Is result satisfactory? “WHT” or “BLK” circuit
open or short.
Replace input shaft
speed sensor.
