P0740 TORQUE CONVERTER
DescriptionINFOID:0000000005928164
• The torque converter clutch solenoid valve is activated, with the gear in D4 and D3, by the TCM in response
to signals sent from the output speed sensor and t he ECM (throttle opening). Lock-up 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 2/8) on lock-up condition, the engine speed should not
change abruptly. If there is an abrupt change in engine speed, there is no lock-up.

• This is an OBD-II self-diagnostic item.
• Diagnostic trouble code “P0740 T/C CLUTCH SOL” with CO NSULT-III or 7th judgement flicker without CON-
SULT-III is detected when TCM detects an improper vo ltage drop while it tries to operate solenoid valve.
Possible CauseINFOID:0000000005928167
• Torque converter clutch solenoid valve
• Harness or connector
(The solenoid circuit is open or shorted.)
DTC Confirmation ProcedureINFOID:0000000005928168
CAUTION:
• Always drive vehicle at a safe speed.
• If performing this “DTC Confirmation Procedure” again, always turn ignition switch OFF and wait at
least 10 seconds before continuing.
After the repair, perform the following procedure to confirm the malfunction is eliminated.
WITH CONSULT-III
1. Turn ignition switch ON. (Do not start engine.)
2. Select “DATA MONITOR” mode for “TRANSMISSION” with CONSULT-III and wait at least 1 second.
3. Touch “START”.
4. Start engine and maintain the following conditions for at least 5 consecutive seconds. VEHICLE SPEED: 80 km/h (50 MPH) or more
THROTTLE POSI: 0.5/8 - 1.0/8
SLCT LVR POSI: “D” position
Driving location: Driving the vehic le uphill (increased engine load) will help maintain the driving
conditions required for this test.
5. If the check result is NG, go to AT-125, "
Diagnosis Procedure".
WITH GST
Follow the procedure “WITH CONSULT-III”.
WITHOUT CONSULT-III
1. Start engine.
2. Drive vehicle in D
1→ D2→ D3→ D4→ D4 lock-up position.
3. Perform self-diagnosis. Refer to AT-82, "
Diagnosis Procedure without CONSULT-III" .
4. If the check result is NG, go to AT-125, "

P0744 TORQUE CONVERTER
DescriptionINFOID:0000000005928172
• This malfunction will not be detected while the OD OFF indicator lamp is indicating another self-diagnosismalfunction.
• This malfunction is detected when the A/T does not shif t into fourth gear position or the torque converter
clutch does not lock-up as instructed by the TCM. This is not caused by electrical malfunction (circuits open
or shorted) but by mechanical malfunction such as c ontrol valve sticking, improper solenoid valve operation,
malfunctioning oil pump or torque converter clutch, etc.
CONSULT-III Reference Value in Data Monitor ModeINFOID:0000000005928173
Remarks: Specification data are reference values.
On Board Diagn osis LogicINFOID:0000000005928174
• This is an OBD-II self-diagnostic item.
• Diagnostic trouble code “P0744 T/C CLUTCH FNCTN” wit h CONSULT-III is detected when A/T cannot per-
form lock-up even if electrical circuit is good.
• This diagnosis monitors actual gear position by checki ng the torque converter slip ratio calculated by TCM
as follows:
Torque converter slip ratio = A x C/B
A: Output shaft revolution signal from output speed sensor
B: Engine speed signal from ECM
C: Gear ratio determined as gear position which TCM supposes
If the actual gear position is much lower than the pos ition (4th) supposed by TCM, the slip ratio will be much
less than normal. In case the ratio does not reach t he specified value, TCM judges this diagnosis malfunc-
tion.
This malfunction will be caused when shift solenoid valve B is stuck closed.
• Gear positions supposed by TCM are as follows.
In case of gear position with no malfunctions: 1, 2, 3 and 4 positions
In case of gear position with shift solenoid valve B stuc k closed: 1, 2, 2 and 1* positions to each gear position
above
*: “P0744 T/C CLUTCH FNCTN” is detected.
Possible CauseINFOID:0000000005928175
• Line pressure solenoid valve
• Torque converter clutch solenoid valve
• Each clutch
• Hydraulic control circuit
DTC Confirmation ProcedureINFOID:0000000005928176
CAUTION:
• Always drive vehicle at a safe speed.
• If performing this “DTC Confirmation Procedure” again, always turn ignition switch OFF and wait at
least 10 seconds before continuing.
After the repair, perform the following proc edure to confirm the malfunction is eliminated.
WITH CONSULT-III
1. Start engine and select “DATA MONITOR” m ode for “TRANSMISSION” with CONSULT-III.
2. Touch “START”.
3. Make sure that output voltage of A/T fluid temperature sensor is within the range below.
FLUID TEMP SE: 0.4 - 1.5 V
If out of range, drive vehicle to decrease voltage (warm up the fluid) or stop engine to increase voltage
(cool down the fluid).
4. Select “TCC S/V FNCTN P0744” of “DTC & SR T CONFIRMATION” mode for “TRANSMISSION” with
CONSULT-III and touch “START”.
