DTC P0720 VEHICLE SPEED SENSOR CVT (SECONDARY SPEED SENSOR)
PFP:31935
Description
ACS002SY
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.
NOTE:
CONSULT-II screen terms are shown differently depending on the version of CONSULT-II card.
CONSULT-II Reference Value
ACS002SZ
Remarks: Specification data are reference values.
On Board Diagnosis Logic

●
This is an OBD-II self-diagnostic item.
●
Diagnostic trouble code “VEH SPD SEN/CIR AT” with CONSULT-II or P0720 without CONSULT-II is
detected TCM does not receive the proper signal from the sensor.
Possible Cause
ACS002T1
●
Harness or connectors
(The sensor circuit is open or shorted.)
●
Output speed sensor (secondary speed sensor)
DTC Confirmation Procedure
ACS002T2
CAUTION:
●
Always drive vehicle at a safe speed.
●
Be careful not to rev engine into the red zone on the tachometer.
NOTE:
If “DTC Confirmation Procedure” has been previously performed, always turn ignition switch “OFF”
and wait at least 5 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
“ENGINE” with CONSULT-II.
2.
Start engine and maintain the following conditions for at least 12
consecutive seconds.

DTC P0730 BELT DAMAGE
PFP:31935
Description
ACS002IU
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 change the operating pressure of the primary
pulley and the secondary pulley and change the groove width of the pulley.
CONSULT-II Reference Value
ACS002T4
Remarks: Specification data are reference values.
On Board Diagnosis Logic
ACS002IV
●
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 “BELT DAMAGE” with CONSULT-II is detected, when TCM receives the unex-
pected gear ratio detected.
Possible Cause
ACS002IW
●
Transaxle assembly
DTC Confirmation Procedure
ACS002T5
CAUTION:
●
Always drive vehicle at a safe speed.
●
Be careful not to rev engine into the red zone on the tachometer.
NOTE:
If “DTC Confirmation Procedure” has been previously performed, always turn ignition switch “OFF”
and wait at least 5 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.
FLUID TEMP SEN: 1.0 - 2.0V
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)

DTC P0740 TORQUE CONVERTER CLUTCH SOLENOID VALVE
Revision; 2004 April
2003 Murano
DTC P0740 TORQUE CONVERTER CLUTCH SOLENOID VALVE
PFP:31940
Description
ACS00210
●
The torque converter clutch solenoid valve is activated by the TCM in response to signals sent from the
vehicle speed and throttle 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 2/8) 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
ACS00211
Remarks: Specification data are reference values.
On Board Diagnosis Logic
ACS00212
●
This is an OBD-II self-diagnostic item.
●
Diagnostic trouble code “TCC SOLENOID/CIRC” with CONSULT-II or P0740 without CONSULT-II is
detected under the following conditions.
–
When TCM detects an improper voltage drop when it tries to operate the solenoid valve.
Possible Cause
ACS00213
●
Torque converter clutch solenoid valve
●
Harness or connectors
(The solenoid circuit is open or shorted.)
DTC Confirmation Procedure
ACS00214
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-
