DTC P1710 A/T FLUID TEMPERATURE SENSOR CIRCUIT
DTC P1710 A/T FLUID TEMPERATURE SENSOR CIRCUIT
Description
INFOID:0000000001327233
The A/T fluid temperature sensor detects the A/T fluid temperature and sends a signal to the TCM.
CONSULT-III Reference Value in Data Monitor Mode
INFOID:0000000001327234
On Board Diagnosis Logic
INFOID:0000000001327235
Diagnostic trouble code “P1710 (A/T), P0710 (ENGINE) ATF TEMP SEN/CIRC” with CONSULT-III or 10th
judgement flicker without CONSULT-III is detected when TCM receives an excessively low or high voltage
from the sensor.
Possible Cause
INFOID:0000000001327236
• Harness or connectors
(Sensor circuit is open or shorted.)
• A/T fluid temperature sensors 1 and/or 2
DTC Confirmation Procedure
INFOID:0000000001327237
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
If “DTC Confirmation Procedure” has been previously performed, always turn ignition switch OFF and
wait at least 10 seconds before performing the next test.
After the repair, perform the following procedure to confirm the malfunction is eliminated.
WITH CONSULT-III
1.
Turn ignition switch ON.
2.
Select “SELECTION FROM MENU” in “DATA MONITOR” mode for “TRANSMISSION” with CONSULT-III
and check monitor “VHCL/S SE-A/T”, “ACCELE POSI” and “SLCT LVR POSI”.
3.
Touch “START”.
4.
Start engine and maintain the following conditions for at least 10 minutes (Total). (It is not necessary to
maintain continuously.)
VHCL/S SE-A/T: 10 km/h (6 MPH) or more
ACCELE POSI: More than 1.0/8
SLCT LVR POSI: “D” position
5.
If DTC is detected, go to
AT-133, "Diagnosis Procedure"
.
WITH GST
Follow the procedure “WITH CONSULT-III”.
