TORQUE CONVERTER CLUTCH SOLENOID VALVE
TORQUE CONVERTER CLUTCH SOLENOID VALVE
PFP:31940
DescriptionECS007S8
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.

ON BOARD DIAGNOSIS LOGIC
SELF-DIAGNOSIS CODE CONFIRMATION PROCEDURE
After the repair, perform the following procedure to confirm the malfunction is eliminated.
With CONSULT-II
1. Start engine.
2. Select “SELF-DIAG RESULTS” mode for A/T with CONSULT-II.
3. Drive vehicle under the following conditions:
Selector lever in “D” position, vehicle speed higher than 10 km/h
(6 MPH), throttle opening greater than 1/8 of the full open posi-
tion, engine speed higher than 450 rpm and driving for more
than 10 minutes.
4. If DTC is detected, go to AT- 3 8 0 , "
Diagnostic Procedure" .
Without CONSULT-II
1. Start engine.
2. Drive vehicle under the following conditions:
Selector lever in “D” position, vehicle speed higher than 10 km/h
(6 MPH), throttle opening greater than 1/8 of the full open posi-
tion, engine speed higher than 450 rpm and driving for more
than 10 minutes.
3. Perform self-diagnosis.
Refer to AT- 5 1 , "
TCM SELF-DIAGNOSTIC PROCEDURE (NO
TOOLS)" (EURO OBD) or AT-250, "Diagnostic Procedure With-
out CONSULT-II" (Except EURO OBD).
4. If DTC is detected, go to AT- 3 8 0 , "
Diagnostic Procedure" .
