Revision: 2006 November2007 350Z
DTC P0740 TORQUE CONVERTER CLUTCH SOLENOID VALVEPFP:31940
DescriptionNCS0003I

Torque converter clutch solenoid valve is activated, with the gear in D4 , D5 , M2 , M3 , M4 and M5 by the
TCM in response to signals sent from the vehicle speed sensor and accelerator pedal position sensor
(throttle position sensor). Torque converter clutch piston operation will then be controlled.

Lock-up operation, however, is prohibited when A/T fluid temperature is too low.

When the accelerator pedal is depressed (less than 1.0/8) 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-III Reference ValueNCS0003J
On Board Diagnosis LogicNCS0003K

This is an OBD-II self-diagnostic item.

Diagnostic trouble code “P0740 TCC SOLENOID/CIRC” with CONSULT-III or 3rd judgment flicker without
CONSULT-III is detected under the following conditions.
–When TCM detects an improper voltage drop when it tries to operate the solenoid valve.
–When TCM detects as irregular by comparing target value with monitor value.
Possible CauseNCS0003L

Torque converter clutch solenoid valve

Harness or connectors
(Solenoid circuit is open or shorted.)
DTC Confirmation ProcedureNCS0003M
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” and “SLCT LVR POSI”.
3. Touch “START”.
4. Start engine and maintain the following conditions for at least 5 consecutive seconds.
VHCL/S SE-A/T: 80 km/h (50 MPH) or more
ACCELE POSI: 0.5/8 – 1.0/8
SLCT LVR POSI: “D” position
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 2 6 , "
Diagnostic Procedure" .
WITH GST
Follow the procedure “WITH CONSULT-III”.
