DTC P0717 TURBINE REVOLUTION SENSOR
Revision: 2006 November2007 350Z
DTC P0717 TURBINE REVOLUTION SENSORPFP:31935
DescriptionNCS0019V
The turbine revolution sensor detects input shaft rpm (revolutions per minute). It is located on the input side of
the A/T. Monitors revolution of sensor 1 and sensor 2 for non-standard conditions.
CONSULT-III Reference ValueNCS0019W
On Board Diagnosis LogicNCS0019X

This is an OBD-II self-diagnostic item.

Diagnostic trouble code “P0717 TURBINE REV S/CIRC” with CONSULT-III or 11th judgment flicker with-
out CONSULT-III is detected under the following conditions.
–When TCM does not receive the proper voltage signal from the sensor.
–When TCM detects an irregularity only at position of 4th gear for turbine revolution sensor 2.
Possible CauseNCS0019Y

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

Turbine revolution sensor 1 and/or 2
DTC Confirmation ProcedureNCS0019Z
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-III
1. Turn ignition switch ON.
2. Select “SELECTION FROM MENU” in “DATA MONITOR” mode for “TRANSMISSION” with CONSULT-III
and check monitor “VHCL/S SE-A/T”, “ACCELE POSI”, “ENGINE SPEED”, “SLCT LVR POSI” and
“GEAR”.
3. Touch “START”.
4. Start engine and maintain the following conditions for at least 5 consecutive seconds.
VHCL/S SE-A/T: 40 km/h (25 MPH) or more
ACCELE POSI: More than 0.5/8
ENGINE SPEED: 1,500 rpm or more
SLCT LVR POSI: “D” position
GEAR (Turbine revolution sensor 1): “4” or “5” position
GEAR (Turbine revolution sensor 2): All positions
Driving location: Driving the vehicle uphill (increased engine load) will help maintain the driving
conditions required for this test.
5. If DTC is detected, go to AT- 1 0 7 , "
Diagnostic Procedure" .
WITH GST
Follow the procedure “WITH CONSULT-III”.
Item name Condition Display value
TURBINE REV During driving (lock-up ON) Approximately matches the engine speed.

DTC P0720 VEHICLE SPEED SENSOR A/T (REVOLUTION SENSOR)
Revision: 2006 November2007 350Z
DTC P0720 VEHICLE SPEED SENSOR A/T (REVOLUTION SENSOR)PFP:32702
DescriptionNCS00035
The revolution sensor detects the revolution of the parking gear and emits a pulse signal. The pulse signal is
sent to the TCM which converts it into vehicle speed.
CONSULT-III Reference ValueNCS00036
On Board Diagnosis LogicNCS00037

This is an OBD-II self-diagnostic item.

Diagnostic trouble code “P0720 VEH SPD SEN/CIR AT” with CONSULT-III or 1st judgment flicker without
CONSULT-III is detected under the following conditions.
–When TCM does not receive the proper voltage signal from the sensor.
–After ignition switch is turned ON, irregular signal input from vehicle speed sensor MTR before the vehicle
starts moving.
Possible CauseNCS00038

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

Revolution sensor

Vehicle speed sensor MTR
DTC Confirmation ProcedureNCS00039
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 10 seconds before performing the next test.
After the repair, perform the following procedure to confirm the malfunction is eliminated.
WITH CONSULT-III
1. Turn ignition switch ON.
2. Select “ECU INPUT SIGNALS” in “DATA MONITOR” mode for “TRANSMISSION” with CONSULT-III.
3. Touch “START”.
4. Drive vehicle and check for an increase of “VHCL/S SE-A/T” value in response to “VHCL/S SE-MTR”
value.
If the check result is NG, go to AT- 111 , "
Diagnostic Procedure" .
If the check result is OK, go to following step.
5. Select “SELECTION FROM MENU” in “DATA MONITOR” mode for “TRANSMISSION” with CONSULT-III
and check monitor “VHCL/S SE-A/T”, “ACCELE POSI”, “ENGINE SPEED” and “SLCT LVR POSI”.
