Turn ignition switch ON.

2.

Select “DATA MONITOR”.

3.

Start engine and maintain the following conditions for at least 5 consecutive seconds.

With GST

Follow the procedure “With CONSULT-III”.

Is “P0715 INPUT SPD SEN/CIRC” detected?

YES

>> Go to

TM-231, "Diagnosis Procedure"

.

NO

>> Check intermittent incident. Refer to

GI-39, "Intermittent Incident"

.

Diagnosis Procedure

INFOID:0000000000988663

1.

CHECK PRIMARY SPEED SENSOR

INPUT SPD SEN/CIRC

• Input speed sensor (primary

speed sensor) signal is not
input due to an open circuit.

• An unexpected signal is input

when vehicle is being driven.

• Harness or connectors

(Sensor circuit is open or
shorted.)

• Input speed sensor (Primary

speed sensor)

VEHICLE SPEED

P0720 VEHICLE SPEED SENSOR CVT (SECONDARY SPEED SENSOR)

Description

INFOID:0000000000988664

The vehicle speed sensor CVT [output speed sensor (secondary speed sensor)] detects the revolution of the
CVT output shaft and emits a pulse signal. The pulse signal is sent to the TCM, which converts it into vehicle
speed.
