P1705 TP SENSOR
Description
INFOID:0000000007357192
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.

WITH GST
Follow the procedure “WITH CONSULT”.
Judgment of Interlock
INFOID:0000000007357215
When interlock is judged to be malfunctioning, the vehicle should be fixed in 2GR, and should be set in a con-
dition in which it can travel.
When one of the following fastening patterns is detected, the fail-safe function in correspondence with the indi-
vidual pattern should be performed.
NOTE:
When the vehicle is driven in 2GR, a input speed sensor malfunction is displayed, but this is not a
input speed sensor malfunction.
When interlock is detected at the 3GR or more, it is locked at the 2GR.
Diagnosis Procedure
INFOID:0000000007357216
1.
SELF-DIAGNOSIS
With CONSULT
1. Drive vehicle.
2. Stop vehicle and turn ignition switch OFF.
3. Turn ignition switch ON.
4. Select “SELF-DIAG RESULTS” mode for “TRANSMISSION” with CONSULT.
