P1705

DTC P1705 THROTTLE POSITION SENSOR





Description
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 communication.




CONSULT-III Reference Value in Data Monitor Mode









On Board Diagnosis Logic
- This is not an OBD-II self-diagnostic item.
- Diagnostic trouble code "P1705 TP SEN/CIRC A/T" with CONSULT-III or 15th judgement flicker without
CONSULT-III is detected when TCM does not receive the proper accelerator pedal position signals (input by
CAN communication) from ECM.




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




DTC Confirmation Procedure

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". (Do not start engine.)
2. Select "DATA MONITOR" mode for "TRANSMISSION" with CONSULT-III.
3. Start engine and let it idle for 1 second.
4. If DTC is detected, go to "Diagnosis Procedure".




Diagnosis Procedure
1.CHECK CAN COMMUNICATION LINE
Perform the self-diagnosis. Refer to CONSULT-III Function (Transmission).
Is a malfunction in the CAN communication indicated in the results?
YES - Check CAN communication line. Refer to A/T Control System.
NO - GO TO 2.
2.CHECK DTC WITH TCM
With CONSULT-III
1. Turn ignition switch ON. (Do not start engine.)
2. Select "ECU INPUT SIGNALS" in "DATA MONITOR" mode for "TRANSMISSION" with CONSULT-III.
3. Depress accelerator pedal and read out the value of "ACCELE POSI".
4. Select "SELF-DIAG RESULTS" mode for "TRANSMISSION" with CONSULT-III. Refer to CONSULT-III Function (Transmission).
Is the inspection result normal?
YES - GO TO 4.
NO - GO TO 3.
3.CHECK DTC WITH ECM
With CONSULT-III
1. Turn ignition switch ON. (Do not start engine.)
2. Select "SELF-DIAG RESULTS" mode for "ENGINE" with CONSULT-III. Refer to CONSULT-III Function.
Is the inspection result normal?
YES - GO TO 4.
NO - Check the DTC detected item. Refer to CONSULT-III Function.
- If CAN communication line is detected, go to A/T Control System.
4.CHECK DTC
Perform "DTC Confirmation Procedure".
- Refer to "DTC Confirmation Procedure".
Is the inspection result normal?
YES - INSPECTION END
NO - GO TO 5.
5.CHECK TCM POWER SUPPLY AND GROUND CIRCUIT
Check TCM power supply and ground circuit. Refer to Main Power Supply And Ground Circuit.
Is the inspection result normal?
YES - GO TO 6.
NO - Repair or replace damaged parts.
6.DETECT MALFUNCTIONING ITEM
Check the following.
- The A/T assembly harness connector pin terminals for damage or loose connection with harness connector.
