DTC P0733 A/T 3RD GEAR FUNCTION

WITH CONSULT-II
1. Start engine and select “DATA MONITOR” mode for “A/T” with
CONSULT-II.
2. Make sure that output voltage of A/T fluid temperature sensor is
within the range below.
FLUID TEMP SEN: 0.4 - 1.5V
If out of range, drive the vehicle to decrease the voltage (warm
up the fluid) or stop engine to increase the voltage (cool down
the fluid).
3. Select “3RD GR FNCTN P0733” of “DTC WORK SUPPORT”
mode for “A/T” with CONSULT-II and touch “START”.
4. Accelerate vehicle to 55 to 70 km/h (34 to 44 MPH) under the
following condition and release the accelerator pedal com-
pletely.
THROTTLE POSI: Less than 1.0/8 (at all times during step 4)
Selector lever: D position (O/D “ON”)
–Make sure that “GEAR” shows “4” after releasing pedal.
5. Depress accelerator pedal steadily with 3.5/8 - 4.5/8 of “THROT-
TLE POSI” from a speed of 55 to 70 km/h (34 to 44 MPH) until
“TESTING” changes to “STOP VEHICLE” or “COMPLETED”. (It
will take approximately 3 seconds.)
If the check result NG appears on CONSULT-II screen, go to AT-
138, "Diagnostic Procedure" .
If “STOP VEHICLE” appears on CONSULT-II screen, go to following step.
–Make sure that “GEAR” shows “3” when depressing accelerator pedal with 3.5/8 - 4.5/8 of
“THROTTLE POSI”.
–If “TESTING” does not appear on CONSULT-II for a long time, select “SELF-DIAGNOSIS” for
“ENGINE”. In case a 1st trip DTC other than P0733 is shown, refer to applicable “TROUBLE DIAG-
NOSIS FOR DTC”.
6. Stop vehicle.
7. Follow the instruction displayed. (Check for normal shifting referring to the table below.)
8. Make sure that “OK” is displayed. (If “NG” is displayed, refer to Diagnostic Procedure.)
Refer to AT- 1 3 8 , "
Diagnostic Procedure" .
Refer to AT- 5 3 0 , "
Shift Schedule" .

CAUTION:

Always drive vehicle at a safe speed.

If conducting this “DTC Confirmation Procedure” again, always turn ignition switch “OFF” and
wait at least 5 seconds before continuing.

Be careful not to rev engine into the red zone on the tachometer.
NOTE:
If “DTC Confirmation Procedure” has been previously conducted, always turn ignition switch OFF and
wait at least 5 seconds before conducting the next test.
TESTING CONDITION:
Always drive vehicle on a level road to improve the accuracy of test.
After the repair, perform the following procedure to confirm the malfunction is eliminated.
WITH CONSULT-II
1. Start engine and select “DATA MONITOR” mode for “A/T” with
CONSULT-II.
2. Make sure that output voltage of A/T fluid temperature sensor is
within the range below.
FLUID TEMP SEN: 0.4 - 1.5V
If out of range, drive the vehicle to decrease the voltage (warm
up the fluid) or stop engine to increase the voltage (cool down

3. Select “4TH GR FNCTN P0734” of “DTC WORK SUPPORT”
mode for “A/T” with CONSULT-II and touch “START”.
4. Accelerate vehicle to 55 to 65 km/h (34 to 40 MPH) under the
following condition and release the accelerator pedal com-
pletely.
THROTTLE POSI: Less than 5.5/8 (at all times during step 4)
Selector lever: D position (O/D “ON”)
–Check that “GEAR” shows “3” after releasing pedal.
5. Depress accelerator pedal steadily with 1.0/8 - 2.0/8 of “THROT-
TLE POSI” from a speed of 55 to 65 km/h (34 to 40 MPH) until
“TESTING” has turned to “STOP VEHICLE” or “COMPLETED”.
(It will take approximately 3 seconds.)
If the check result NG appears on CONSULT-II screen, go to AT-
144, "Diagnostic Procedure" .
If “STOP VEHICLE” appears on CONSULT-II screen, go to following step.
–Check that “GEAR” shows “4” when depressing accelerator pedal with 1.0/8 - 2.0/8 of “THROTTLE

DTC P0740 TORQUE CONVERTER CLUTCH SOLENOID VALVE

DTC P0740 TORQUE CONVERTER CLUTCH SOLENOID VALVEPFP:31940
DescriptionECS004RQ
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.

1. Turn ignition switch ON. (Do not start engine.)
2. Select “DATA MONITOR” mode for “A/T” with CONSULT-II and
wait at least 1 second.

DTC P0745 LINE PRESSURE SOLENOID VALVEPFP:31940
DescriptionECS004RU
The line pressure solenoid valve regulates the oil pump discharge
pressure to suit the driving condition in response to a signal sent
from the TCM.
The line pressure duty cycle value is not consistent when the
closed throttle position switch is ON. To confirm the line pres-
sure duty cycle at low pressure, the accelerator (throttle)
should be open until the closed throttle position switch is OFF.
CONSULT-II REFERENCE VALUE IN DATA MONITOR MODE
Remarks: Specification data are reference values.
NOTE:
The line pressure duty cycle value is not consistent when the closed throttle position switch is “ON”. To confirm the line pressure duty
cycle at low pressure, the accelerator (throttle) should be open until the closed throttle position switch is “OFF”.
