DTC P0731 A/T 1ST GEAR FUNCTIONPFP:31940
DescriptionECS004RA
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 first 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 LogicECS00CTS
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 (1st) 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 either shift solenoid valve A is stuck open or shift solenoid valve B is
stuck open.
*: P0731 is detected.
Possible CauseECS00CTT
Check the following items.
Shift solenoid valve A
Shift solenoid valve B
Each clutch
Hydraulic control circuit
DTC Confirmation ProcedureECS00CTU
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.
Gear position 1 2 3 4
Shift solenoid valve A ON (Closed) OFF (Open) OFF (Open) ON (Closed)
Shift solenoid valve B ON (Closed) ON (Closed) OFF (Open) OFF (Open)
Gear position supposed by TCM 1 2 3 4
In case of gear position with no malfunctions 1 2 3 4
In case of gear position with shift solenoid valve A stuck open 2* 2 3 3
In case of gear position with shift solenoid valve B stuck open 4* 3 3 4
Diagnostic trouble code Malfunction is detected when... Check items (Possible cause)
: A/T 1ST GR FNCTN
A/T cannot be shifted to the 1st gear posi-
tion even if electrical circuit is good.

DTC P0731 A/T 1ST 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 “1ST GR FNCTN P0731” of “DTC WORK SUPPORT”
mode for “A/T” with CONSULT-II and touch “START”.
4. Accelerate vehicle to 15 to 20 km/h (9 to 12 MPH) under the fol-
lowing condition and release the accelerator pedal completely.
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 “2” after releasing pedal.
5. Depress accelerator pedal to WOT (more than 7.0/8 of “THROT-
TLE POSI”) quickly from a speed of 15 to 20 km/h (9 to 12 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-
128, "Diagnostic Procedure" .
If “STOP VEHICLE” appears on CONSULT-II screen, go to the
following step.
–Make sure that “GEAR” shows “1” 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 P0731 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 2 8 , "
Diagnostic Procedure" .
Refer to AT- 5 3 0 , "
Shift Schedule" .
WITH GST
Follow the procedure “WITH CONSULT-II”.
