DTC P0720 VEHICLE SPEED SENSOR CVT (SECONDARY SPEED SENSOR)

Revision: 2006 July

2007 Murano

DTC P0720 VEHICLE SPEED SENSOR CVT (SECONDARY SPEED SENSOR)

PFP:31935

Description

NCS0014G

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.

CONSULT-II Reference Value

NCS0014H

Remarks: Specification data are reference values.

On Board Diagnosis Logic

●

This is an OBD-II self-diagnostic item.

●

Diagnostic trouble code “P0720 VEH SPD SEN/CIR AT” with CONSULT-II is detected TCM does not
receive the proper signal from the sensor.

Possible Cause

NCS0014J

●

Harness or connectors
(Sensor circuit is open or shorted.)

●

Output speed sensor (Secondary speed sensor)

DTC Confirmation Procedure

NCS0014K

CAUTION:

Always drive vehicle at a safe speed.

NOTE:
If “DTC Confirmation Procedure” has been previously performed, always turn ignition switch OFF and
wait at least 10 seconds before performing the next test.
After the repair, touch “ERASE” on “SELF-DIAG RESULTS” and then perform the following procedure to con-
firm the malfunction is eliminated.

 WITH CONSULT-II

1.

Turn ignition switch ON and select “DATA MONITOR” mode for
“TRANSMISSION” with CONSULT-II.

2.

Start engine and maintain the following conditions for at least 12
consecutive seconds.
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 DTC is detected, go to 

CVT-96, "Diagnostic Procedure"

 .

 WITH GST

Follow the procedure “WITH CONSULT-II”.

DTC P0730 BELT DAMAGE

PFP:31935

Description

NCS0014T

TCM selects the gear ratio using the engine load (throttle position), the primary pulley revolution speed, and
the secondary pulley revolution speed as input signal. Then it changes the operating pressure of the primary
pulley and the secondary pulley and changes the groove width of the pulley.

CONSULT-II Reference Value

NCS0014U

Remarks: Specification data are reference values.

On Board Diagnosis Logic

NCS0014V

●

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

●

TCM calculates the actual gear ratio with input speed sensor (primary speed sensor) and output speed
sensor (secondary speed sensor).

●

Diagnostic trouble code “P0730 BELT DAMG” with CONSULT-II is detected, when TCM receives an unex-
pected gear ratio signal.

Possible Cause

NCS0014W

Transaxle assembly

DTC Confirmation Procedure

NCS0014X

CAUTION:

Always drive vehicle at a safe speed.

NOTE:
If “DTC Confirmation Procedure” has been previously performed, always turn ignition switch OFF and
wait at least 10 seconds before performing the next test.
After the repair, perform the following procedure to confirm the malfunction is eliminated.

 WITH CONSULT-II

1.

Turn ignition switch ON and select “DATA MONITOR” mode for
“TRANSMISSION” with CONSULT-II.

2.

Make sure that output voltage of CVT fluid temperature sensor
is within the range below.
ATF TEMP SEN: 1.0 – 2.0 V
If out of range, drive the vehicle to decrease the voltage
(warm up the fluid) or stop engine to increase the voltage
(cool down the fluid)

3.

Select “DATA MONITOR” mode for “TRANSMISSION” with
CONSULT-II.

4.

Start engine and maintain the following conditions for at least 30
consecutive seconds.
TEST START FROM 0 km/h (0 MPH)
CONSTANT ACCELERATION: Keep 30 sec or more
VEHICLE SPEED: 10 km/h (6 MPH) or more

DTC P0740 TORQUE CONVERTER CLUTCH SOLENOID VALVE

Revision: 2006 July

2007 Murano

DTC P0740 TORQUE CONVERTER CLUTCH SOLENOID VALVE

PFP:31940

Description

NCS0014Z

●

The torque converter clutch solenoid valve is activated by the TCM in response to signals sent from the
vehicle speed and accelerator pedal position sensors. Lock-up piston operation will then be controlled.

●

Lock-up operation, however, is prohibited when CVT fluid temperature is too low.

●

When the accelerator pedal is depressed (less than 2.0/8) in lock-up condition, the engine speed should
not change abruptly. If there is a big jump in engine speed, there is no lock-up.

CONSULT-II Reference Value

NCS00150

Remarks: Specification data are reference values.

On Board Diagnosis Logic

NCS00151

●

This is an OBD-II self-diagnostic item.

●

Diagnostic trouble code “P0740 TCC SOLENOID/CIRC” with CONSULT-II is detected under the following
conditions.

–

TCM detects an improper voltage drop when it tries to operate the solenoid valve.

Possible Cause

NCS00152

●

Torque converter clutch solenoid valve

●

Harness or connectors
(Solenoid circuit is open or shorted.)

DTC Confirmation Procedure

NCS00153

NOTE:
If “DTC Confirmation Procedure” has been previously performed, always turn ignition switch OFF and
wait at least 10 seconds before performing the next test.
After the repair, touch “ERASE” on “SELF-DIAG RESULTS” and then perform the following procedure to con-
firm the malfunction is eliminated.
