DTC P1710 A/T FLUID TEMPERATURE SENSOR CIRCUIT

PFP:31940

Description

NCS000WO

The A/T fluid temperature sensor detects the A/T fluid temperature and sends a signal to the TCM.

CONSULT-II Reference Value

NCS000WP

On Board Diagnosis Logic

NCS000WQ

This is an OBD-II self-diagnostic item.

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

Possible Cause

NCS000WR

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

A/T fluid temperature sensors 1 and/or 2

DTC Confirmation Procedure

NCS000WS

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-II

1.

Turn ignition switch ON. (Do not start engine.)

2.

Select “SELECTION FROM MENU” in “DATA MONITOR” mode
for “A/T” with CONSULT-II 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-131, "Diagnostic Procedure"

 .
