DTC P1710 A/T FLUID TEMPERATURE SENSOR CIRCUIT

PFP:31940

Description

ACS00486

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

CONSULT-II Reference Value

ACS00487

On Board Diagnosis Logic

ACS00488

This is an OBD-II self-diagnostic item.

Diagnostic trouble code “ATF TEMP SEN/CIRC” with CONSULT-II or P1710 (A/T), P0710 (ENGINE) with-
out CONSULT-II is detected when TCM receives an excessively low or high voltage from the sensor.

Possible Cause

ACS00489

Harness or connectors
(The sensor circuit is open or shorted.)

A/T fluid temperature sensors 1, 2

DTC Confirmation Procedure

ACS0048A

CAUTION:

Always drive vehicle at a safe speed.

NOTE:
If “DTC Confirmation Procedure” has been previously conducted, always turn ignition switch OFF and

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 “DATA MONITOR” mode for “A/T” with CONSULT-II.

3.

Start engine and maintain the following conditions for at least 10
minutes (Total). (It is not necessary to maintain continuously.)
VHCL SPEED SE: 10 km/h (6 MPH) or more
THROTTLE POSI: More than 1.0/8
Selector lever: “D” position

4.

If DTC is detected, go to 

AT-156, "Diagnostic Procedure"

 .

 WITH GST

Follow the procedure “With CONSULT-II”.
