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.

On Board Diagnosis Logic

INFOID:0000000007357194

• This is not an OBD-II self-diagnostic item.

• Diagnostic trouble code “P1705” with CONSULT or 15th judgment flicker without CONSULT is detected

when TCM does not receive the proper accelerator pedal position signals (input by CAN communication)

from ECM.

P1721 VEHICLE SPEED SIGNAL

P1721 VEHICLE SPEED SIGNAL

Description

INFOID:0000000007357205

The vehicle speed signal is transmitted from combination meter to TCM by CAN communication line. The sig-

nal functions as an auxiliary device to the output speed sensor when it is malfunctioning. The TCM will then

use the vehicle speed signal.

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.

Without CONSULT

1. Drive vehicle.

2. Stop vehicle and turn ignition switch OFF.
