DTC P1705 THROTTLE POSITION SENSORPFP:22620
DescriptionNCS001M9
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-II Reference ValueNCS001MA
On Board Diagnosis LogicNCS001MB

This is an OBD-II self-diagnostic item. (For VQ35DE engine)

Diagnostic trouble code “P1705 TP SEN/CIRC A/T” with CONSULT-II or 15th judgement flicker without
CONSULT-II is detected when TCM does not receive the proper accelerator pedal position signals (input
by CAN communication) from ECM.
Possible CauseNCS001MC
Harness or connectors
(Sensor circuit is open or shorted.)
DTC Confirmation ProcedureNCS001MD
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.
2. Select “ECU INPUT SIGNALS” in “DATA MONITOR” mode for
“A/T” with CONSULT-II.
3. Touch “START”.
4. Start engine and let it idle for 1 second.
5. If DTC is detected, go to AT- 1 3 3 , "
Diagnostic Procedure" .
WITH GST
Follow the procedure “WITH CONSULT-II”.
