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
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.
DTC
Item
(CONSULT-III screen term)
Malfunction is detected when...
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.

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.
