DTC P0740 TORQUE CONVERTER CLUTCH SOLENOID VALVE
Revision: 2006 January2006 M35/M45
DTC P0740 TORQUE CONVERTER CLUTCH SOLENOID VALVEPFP:31940
DescriptionNCS001LR
The torque converter clutch solenoid valve is activated, with the gear in D3 , D4 , D5 , 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 1/8) 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 ValueNCS001LS

This is an OBD-II self-diagnostic item.
Diagnostic trouble code “P0740 TCC SOLENOID/CIRC” with CONSULT-II or 3rd judgement flicker with-
out CONSULT-II 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.
