DTC P1710 A/T FLUID TEMPERATURE SENSOR CIRCUITPFP:31940
DescriptionNCS0004G
The A/T fluid temperature sensor detects the A/T fluid temperature and sends a signal to the TCM.
CONSULT-III Reference ValueNCS0004H
On Board Diagnosis LogicNCS0004I

This is an OBD-II self-diagnostic item.

Diagnostic trouble code “P1710 (A/T), P0710 (ENGINE) ATF TEMP SEN/CIRC” with CONSULT-III or 10th
judgment flicker without CONSULT-III is detected when TCM receives an excessively low or high voltage
from the sensor.

Harness or connectors
(Sensor circuit is open or shorted.)

A/T fluid temperature sensors 1 and/or 2
DTC Confirmation ProcedureNCS0004K
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”.
