P0720 VEHICLE SPEED SENSOR CVT (SECONDARY SPEED SENSOR)
DescriptionINFOID:0000000003806397
The vehicle speed sensor CVT [output speed sensor (secondary speed sensor)] detects the revolution of the
CVT output shaft and emits a pulse signal. The pulse signal is transmitted to the TCM, which converts it into
vehicle speed.

P0740 TORQUE CONVERTER CLUTCH SOLENOID VALVE
DescriptionINFOID:0000000003806406
 The torque converter clutch solenoid valve is activated by the TCM in response to signals sent from the vehi-
cle speed and accelerator pedal position sensors. Lock-up piston operation will then be controlled.
 Lock-up operation, however, is prohibited when CVT fluid temperature is too low.
 When the accelerator pedal is depressed (less than 2.0/8) in lock-up condition, the engine speed shall not
change abruptly. If there is a big jump in engine speed, there is no lock-up.
