P0720 VEHICLE SPEED SENSOR CVT (SECONDARY SPEED SENSOR)

P0720 VEHICLE SPEED SENSOR CVT (SECONDARY SPEED SENSOR)

Description

INFOID:0000000004201883

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 transmitted to the TCM, which converts it into

vehicle speed.

DTC Logic

INFOID:0000000004201884

DTC DETECTION LOGIC

DTC CONFIRMATION PROCEDURE

CAUTION:

Always drive vehicle at a safe speed.

NOTE:

If “DTC CONFIRMATION PROCEDURE” has been previously performed, always turn ignition switch OFF.

Then wait at least 10 seconds before performing the next test.

1.

CHECK DTC DETECTION

With CONSULT-III

1. Turn ignition switch ON.

2. Select “DATA MONITOR”.

3. Start engine and maintain the following conditions for at least 12 consecutive seconds.

With GST

Follow the procedure “With CONSULT-III”.
Is “P0720 VEH SPD SEN/CIR AT” detected?

YES

>> Go to 

TM-318, "Diagnosis Procedure"

.

NO

>> Check intermittent incident. Refer to 

GI-42, "Intermittent Incident"

.

Diagnosis Procedure

INFOID:0000000004201885

1.

CHECK OUTPUT SPEED SENSOR (SECONDARY SPEED SENSOR)

With CONSULT-III

1. Start engine.

2. Check voltage between TCM harness connector F16 terminal 7,

46 and 7, 48.

Possible cause

P0720

VEH SPD SEN/CIR AT

• Signal from vehicle speed sensor CVT 

[output speed sensor (secondary speed 
sensor)] not input due to open or short cir-
cuit.

• An unexpected signal input during running

.

• Harness or connectors

(Sensor circuit is open or shorted.)

• Output speed sensor (secondary speed 

sensor)

ACC PEDAL OPEN

: More than 1.0/8

RANGE

: “D” position

Driving location

: Driving the vehicle uphill (increased engine load) will help maintain the driving 
conditions required for this test.

3. If OK, check pulse when vehicle cruises.

Is the inspection result normal?

YES

>> GO TO 11.

NO

>> GO TO 2.

2.

CHECK POWER AND SENSOR GROUND

1. Turn ignition switch OFF.

2. Disconnect output speed sensor (secondary speed sensor) har-

ness connector.

3. Turn ignition switch ON.

4. Check voltage between output speed sensor (secondary speed

sensor) harness connector F23 terminal 1 and 3.

5. Check voltage between output speed sensor (secondary speed

sensor) harness connector F23 terminal 3 and ground.

Is the inspection result normal?

YES

>> GO TO 3.

NO-1 >> Battery voltage is not supplied between terminals 1 and

3, terminals 3 and ground: GO TO 6.

NO-2 >> Battery voltage is not supplied between terminals 1 and 3 only: GO TO 8.

3.

CHECK HARNESS BETWEEN TCM AND OUTPUT SPEED SENSOR (SECONDARY SPEED SENSOR)

(SENSOR GROUND)

1. Turn ignition switch OFF.

2. Disconnect TCM harness connector.

3. Check continuity between TCM harness connector F16 terminal

7 and ground.

Is the inspection result normal?

YES

>> GO TO 4.

NO

>> Repair or replace damaged parts.
