P1705 TP SENSOR
Description
INFOID:0000000009719496
The electric throttle control actuator consists of throttle control motor, accelerator pedal position sensor, throt-
tle position sensor, etc. The actuator sends a signal to the ECM, and ECM sends the signal to TCM via CAN
communication.

Vehicle Speed Signal Circuit
• CAN communication with the ABS actua-
tor and the electric unit (control unit) is
malfunctioning.
• There is a big difference between the ve-
hicle speed signal from the ABS actuator
and the electric unit (control unit), and the
vehicle speed sensor signal.
• Harness or connectors
(Sensor circuit is open or shorted.)
• ABS actuator and electric unit (control
unit)
ACC PEDAL OPEN
: 1.0/8 or less
VEHICLE SPEED
: 30 km/h (19 MPH) or more
