P1705 TP SENSOR

TM-195

< DTC/CIRCUIT DIAGNOSIS >

[5AT: RE5R05A]

P1705 TP SENSOR

Description

INFOID:0000000009480573

Electric throttle control actuator consists of throttle control motor, accelerator pedal position sensor, throttle

position sensor, etc. The actuator sends a signal to the ECM, and ECM sends signals to TCM with CAN com-

munication.

CONSULT Reference Value in Data Monitor Mode

INFOID:0000000009480574

On Board Diagnosis Logic

INFOID:0000000009480575

• This is not an OBD-II self-diagnostic item.

• Diagnostic trouble code “P1705” with CONSULT or 15th judgment flicker without CONSULT is detected

when TCM does not receive the proper accelerator pedal position signals (input by CAN communication)

from ECM.

Possible Cause

INFOID:0000000009480576

Harness or connectors

(The sensor circuit is open or shorted.)

DTC Confirmation Procedure

INFOID:0000000009480577

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

1. Turn ignition switch “ON”. (Do not start engine.)

2. Select “DATA MONITOR” mode for "TRANSMISSION" with CONSULT.

3. Start engine and let it idle for 1 second.

4. If DTC is detected, go to

P1710 TRANSMISSION FLUID TEMPERATURE SENSOR

TM-197

< DTC/CIRCUIT DIAGNOSIS >

[5AT: RE5R05A]

P1710 TRANSMISSION FLUID TEMPERATURE SENSOR

Description

INFOID:0000000009480579

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

CONSULT Reference Value in Data Monitor Mode

INFOID:0000000009480580

On Board Diagnosis Logic

INFOID:0000000009480581

• This is an OBD-II self-diagnostic item.

• Diagnostic trouble code “P1710 (A/T), P0710 (ENGINE)” with CONSULT or 10th judgment flicker without

CONSULT is detected when:

- TCM receives an excessively low or high voltage from the sensor.

- A/T fluid temperature does not rise to the specified temperature after driving for a certain period of time.

- There is a certain temperature difference between A/T fluid and engine coolant. (Except for Mexico)

Possible Cause

INFOID:0000000009480582

• Harness or connectors

(The sensor circuit is open or shorted.)

• A/T fluid temperature sensor

DTC Confirmation Procedure
