DTC P0732 A/T 2ND GEAR FUNCTIONPFP:31940
DescriptionECS004RE
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 second 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, etc.
On Board Diagnostic LogicECS00CTV
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 (2nd) 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 B is stuck open.
*: P0732 is detected.
Possible CauseECS00CTW
Check the following items.
Shift solenoid valve B
Each clutch
Hydraulic control circuit
DTC Confirmation ProcedureECS00CTX
CAUTION:
Always drive vehicle at a safe speed.
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
the fluid).
3. Select “2ND GR FNCTN P0732” of “DTC WORK SUPPORT”
mode for “A/T” with CONSULT-II and touch “START”.
4. Accelerate vehicle to 35 to 40 km/h (22 to 25 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 “3” or “4” after releasing
pedal.
5. Depress accelerator pedal to WOT (more than 7.0/8 of “THROT-
TLE POSI”) quickly from a speed of 35 to 40 km/h (22 to 25
MPH) until “TESTING” changes to “STOP VEHICLE” or “COM-
PLETED”. (It will take approximately 3 seconds.)
If the check result NG appears on CONSULT-II screen, go to AT-
133, "Diagnostic Procedure" .
If “STOP VEHICLE” appears on CONSULT-II screen, go to following step.
–Make sure that “GEAR” shows “2” when depressing accelerator pedal to WOT.
–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 P0732 is shown, refer to applicable “TROUBLE DIAG-
NOSIS FOR DTC”.
6. Stop vehicle.
7. Follow the instruction displayed. (Check for normal shifting refer-
ring to the table below.)
8. Make sure that “OK” is displayed. (If “NG” is displayed, refer to
“Diagnostic Procedure”.)
Refer to AT- 1 3 3 , "
Diagnostic Procedure" .
Refer to AT- 5 3 0 , "
Shift Schedule" .
WITH GST
Follow the procedure “WITH CONSULT-II”.
