DTC P0740 TORQUE CONVERTER CLUTCH SOLENOID VALVE
PFP:31940
Description
ECS00985
The torque converter clutch solenoid valve is activated, with the gear
in “D
4
”, 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 A/T fluid tempera-
ture 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 IN DATA MONITOR MODE
Remarks: Specification data are reference values.
TCM TERMINALS AND REFERENCE VALUE
Remarks: Specification data are reference values.
