DTC P0740 TORQUE CONVERTER CLUTCH SOLENOID VALVE
DTC P0740 TORQUE CONVERTER CLUTCH SOLENOID VALVE
DescriptionINFOID:0000000001327209
The torque converter clutch solenoid va lve is activated, with the gear in D5, M3, M4 and M5 by the TCM in
response to signals sent from the vehicle speed sensor and accelerator pedal position sensor (throttle posi-
tion 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. 0/8) 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-III Reference Value in Data Monitor ModeINFOID:0000000001327210
On Board Diagnosis LogicINFOID:0000000001327211
Diagnostic trouble code “P0740 TCC SOLENOID/CIRC” with CONSULT-III or 3rd judgement flicker without
CONSULT-III 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.
Possible CauseINFOID:0000000001327212
Torque converter clutch solenoid valve
Harness or connectors (Solenoid circuit is open or shorted.)
DTC Confirmation ProcedureINFOID:0000000001327213
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
If “DTC Confirmation Procedure” has been previously performed, always turn ignition switch “OFF”
and wait at least 10 seconds before performing the next test.
After the repair, perform the following proc edure to confirm the malfunction is eliminated.
WITH CONSULT-III
1. Turn ignition switch ON.
2. Select “SELECTION FROM MENU” in “DATA MONI TOR” mode for “TRANSMISSION” with CONSULT-III
and check monitor “VHCL/S SE-A/T”, “ACCELE POSI” and “SLCT LVR POSI”.
3. Touch “START”.
4. Start engine and maintain the following conditions for at least 5 consecutive seconds. VHCL/S SE-A/T: 80 km/h (50 MPH) or more
ACCELE POSI: 0.5/8 - 1.0/8
SLCT LVR POSI: “D” position
Driving location: Driving the vehicle uphill (increased engine load) will help maintain the driving
conditions required for this test.
5. If DTC is detected go to AT-124, "
Diagnosis Procedure".
