P1705 TP SENSOR
Description
INFOID:0000000009485498
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:0000000009485499
On Board Diagnosis Logic
INFOID:0000000009485500
• 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:0000000009485501
Harness or connectors
(The sensor circuit is open or shorted.)
DTC Confirmation Procedure
INFOID:0000000009485502
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
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
.
Diagnosis Procedure
INFOID:0000000009485503

P1710 TRANSMISSION FLUID TEMPERATURE SENSOR
Description
INFOID:0000000009485504
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:0000000009485505
On Board Diagnosis Logic
INFOID:0000000009485506
• 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:0000000009485507
• Harness or connectors
(The sensor circuit is open or shorted.)
• A/T fluid temperature sensors
DTC Confirmation Procedure
INFOID:0000000009485508
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
Confirmation procedure 1
1. Turn ignition switch “ON”. (Do not start engine.)
2. Select “DATA MONITOR” mode for “TRANSMISSION” with CONSULT.
3. Start engine and maintain the following conditions for 10 seconds or more.
