DTC P0731 A/T 1ST GEAR FUNCTION
DescriptionINFOID:0000000001694313
 This malfunction will not be detected while the OD 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 Diagnosis LogicINFOID:0000000001694314
 This is an OBD self-diagnostic item.
 Diagnostic trouble code “P0731 A/T 1ST GR FNCTN” with CONSULT-III is detected when A/T cannot be
shifted to the 1st gear position even if electrical circuit is good.
 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.
 Gear positions supposed by TCM are as follows:
In case of gear position with no malfunctions: 1, 2, 3 and 4 positions
In case of gear position with shift solenoid valve A stuck open: 2*, 2, 3 and 3 positions
In case of gear position with shift solenoid valve B stuck open: 4*, 3, 3 and 4 positions to each gear position
above
*: “P0731 A/T 1ST GR FNCTN” is detected.
Possible CauseINFOID:0000000001694315
 Shift solenoid valve A
 Shift solenoid valve B
 Each clutch
 Hydraulic control circuit
DTC Confirmation ProcedureINFOID:0000000001694316
CAUTION:
 Always drive vehicle at a safe speed.
 If performing this “DTC Confirmation Procedure” again, always turn ignition switch OFF and wait at
least 10 seconds before continuing.
After the repair, perform the following procedure to confirm the malfunction is eliminated.
WITH CONSULT-III
1. Start engine and select “DATA MONITOR” mode for “A/T” with CONSULT-III.
2. Touch “START”.
3. Make sure that output voltage of A/T fluid temperature sensor is within the range below.
FLUID TEMP SE: 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).
4. Select “1ST GR FNCTN P0731” of “DTC WORK SUPPORT” mode for “A/T” with CONSULT-III and touch
“START”.

5. Accelerate vehicle to 20 to 25 km/h (12 to 16 MPH) under the following conditions and release the accel-
erator pedal completely.
THROTTLE POSI: Less than 1.0/8 (at all times during step 4)
SLCT LVR POSI: “D” position
-Make sure that “GEAR” shows “2” after releasing pedal.
6. Depress accelerator pedal to WOT (more than 7.0/8 of “THROTTLE POSI”) quickly from a speed of 20 to
25 km/h (12 to 16 MPH) until “TESTING” changes to “STOP VEHICLE” or “COMPLETED”. (It will take
approximately 3 seconds.)
If the check result NG appears on CONSULT-III screen, go to TM-60, "
Diagnosis Procedure".
If “STOP VEHICLE” appears on CONSULT-III 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-III for a long time, select “SELF-DIAG RESULTS” for
“A/T”. In case a DTC other than “P0731 A/T 1ST GR FNCTN” is shown, refer to TM-35, "
CONSULT-
III Function (TRANSMISSION)".
7. Stop vehicle.
8. Follow the instruction displayed. (Check for normal shifting referring to the table below.)
9. Make sure that “OK” is displayed. (If “NG” is displayed, refer to “Diagnostic Procedure”.)
Refer to TM-60, "
Diagnosis Procedure".
Refer to TM-319, "
Vehicle Speed at Which Gear Shifting Occurs".
WITH GST
Follow the procedure “WITH CONSULT-III”.
