P0731 1GR INCORRECT RATIO
P0731 1GR INCORRECT RATIO
Description
INFOID:0000000007357149
This malfunction is detected when the A/T does not shift into 1GR position as instructed by TCM. This is not
only caused by electrical malfunction (circuits open or shorted) but also by mechanical malfunction such as
control valve sticking, improper solenoid valve operation.
On Board Diagnosis Logic
INFOID:0000000007357150
• This is an OBD-II self-diagnostic item.
• Diagnostic trouble code “P0731” with CONSULT or 18th judgment flicker without CONSULT is detected
when TCM detects any inconsistency in the actual gear ratio.
Possible Cause
INFOID:0000000007357151
• Harness or connectors
(Solenoid circuits are open or shorted.)
• Input clutch solenoid valve
• Front brake solenoid valve
• Direct clutch solenoid valve
• High and low reverse clutch solenoid valve
• Each clutch
• Hydraulic control circuit
DTC Confirmation Procedure
INFOID:0000000007357152
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
If “DTC Confirmation Procedure” has been previously performed, always turn ignition switch OFF and
wait at least 10 seconds before performing the next test.
After the repair, perform the following procedure to confirm the malfunction is eliminated.
WITH CONSULT
1. Start the engine and select “DATA MONITOR” mode for “TRANSMISSION” with CONSULT.
2. Make sure that “ATF TEMP 1” is within the following range.
ATF TEMP 1: 20 – 140
°
C (68 – 284
°
F)
If out of range, drive vehicle to warm ATF or stop engine to cool ATF.
3. Select “1ST GR FNCTN P0731” of “DTC & SRT CONFIRMATION” mode for “TRANSMISSION” with
CONSULT.
4. Drive vehicle and maintain the following conditions.
With manual mode:
MANU MODE SW: ON
GEAR: “1” position
ACCELE POSI: 0.6/8 or more
VEHICLE SPEED: 10 km/h (6 MPH) or more
ENGINE SPEED: INPUT SPEED
−
50 rpm or more
INPUT SPEED: 300 rpm or more
Without manual mode:
SLCT LVR POSI: “1” position
GEAR: “1” position
ACCELE POSI: 0.6/8 or more
VEHICLE SPEED: 10 km/h (6 MPH) or more
ENGINE SPEED: INPUT SPEED
−
50 rpm or more
INPUT SPEED: 300 rpm or more
5. Keep the current driving status for at least 5 consecutive seconds if CONSULT screen changes from
“OUT OF CONDITION” to “TESTING”.
CAUTION:
If “TESTING” does not appear on CONSULT for a long time, select “SELF-DIAG RESULTS”. In case
a 1st trip DTC other than P0731 is shown, refer to
TM-37, "CONSULT Function (TRANSMISSION)"
.
