Engine Speed Input Circuit

• TCM detects a malfunction in CAN com-

munication between TCM and ECM

• When primary pulley speed is more than 

1,000 rpm, engine speed (CAN signal) is 
less than 450 rpm

• Harness or connectors

(CAN communication line is open or 
shorted.)
(Engine speed signal circuit is open or 
shorted.)

• ECM

P0740 TORQUE CONVERTER

Description

INFOID:0000000009948974

• Torque converter clutch solenoid valve is installed to control valve.
• Torque converter clutch solenoid valve adjusts oil pump discharge pressure to an optimum level according to

the driving conditions.

• The adoption of an N/L type (normal low) torque converter clutch solenoid valve enables generation of a

control oil pressure when a voltage is not applied to the coil.

• Torque converter clutch solenoid valve is controlled by TCM according to signals transmitted from vehicle

speed sensor and accelerator pedal position sensor.

• Lock-up is prohibited when CVT fluid temperature is low.
• When accelerator pedal is depressed (throttle opening angle is less than 2.0/8) in the lock-up state, engine

speed does not suddenly change. If engine speed changes suddenly, lock-up is not applied.
