DTC P0733 A/T 3RD GEAR FUNCTIONPFP:31940
DescriptionECS004RI
●This malfunction will not be detected while the O/D OFF indicator lamp is indicating another self-diagnosis
malfunction.
●This malfunction is detected when the A/T does not shift into third gear position as instructed by the TCM.
This is not caused by electrical malfunction (circuits open or shorted) but by mechanical malfunction such
as control valve sticking, improper solenoid valve operation, malfunctioning servo piston or brake band,
etc.
TCM TERMINALS AND REFERENCE VALUE
Remarks: Specification data are reference values.
ON BOARD DIAGNOSTIC LOGIC
This diagnosis monitors actual gear position by checking the torque converter slip ratio calculated by TCM as
follows:
Torque converter slip ratio = A x C/B
A: Output shaft revolution signal from revolution sensor
B: Engine speed signal from ECM
C: Gear ratio determined as gear position which TCM supposes
If the actual gear position is higher than the position (3rd) supposed by TCM, the slip ratio will be more than
normal. In case the ratio exceeds the specified value, TCM judges this diagnosis malfunction.
This malfunction will be caused when shift solenoid valve A is stuck closed.

DIAGNOSTIC TROUBLE CODE (DTC) CONFIRMATION PROCEDURE
CAUTION:
●Always drive vehicle at a safe speed.
●Be careful not to rev engine into the red zone on the
tachometer.
NOTE:
If “DIAGNOSTIC TROUBLE CODE CONFIRMATION PROCE-
DURE” 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 mal-
function 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 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 (OD “ON”)
●Check 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- 1 4 7 , "
Diagnostic Procedure" .
If “STOP VEHICLE” appears on CONSULT-II screen, go to following step.
●Check 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.)
