DTC P1705 THROTTLE POSITION SENSORPFP:22620
DescriptionNCS0004A
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-III Reference ValueNCS0004B

This is an OBD-II self-diagnostic item.

Diagnostic trouble code “P1705 TP SEN/CIRC A/T” with CONSULT-III or 15th judgment flicker without
CONSULT-III is detected when TCM does not receive the proper accelerator pedal position signals (input
by CAN communication) from ECM.
Possible CauseNCS0004D
Harness or connectors
(Sensor circuit is open or shorted.)
DTC Confirmation ProcedureNCS0004E
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.
