P0732
P0732 2Gr Incorrect RatioDescription
This malfunction is detected when the A/T does not shift into 2GR position as instructed by TCM. This is not only caused by electrical malfunction (circuits open or shorted) but mechanical malfunction such as control valve sticking, improper solenoid valve operation.
On Board Diagnosis Logic
^ This is an OBD-II self-diagnostic item.
^ Diagnostic trouble code "P0732" with SDT or 19th judgment flicker without SDT is detected when TCM detects any inconsistency in the actual gear ratio.
Possible Cause
^ 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
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 SDT
1. Start the engine and select "Data list" mode for "AT" with SDT.
2. Make sure that "ATF TEMP 1" is within the following range.
ATF TEMP 1: 20 degrees C - 180 degrees C
If out of range, drive vehicle to warm ATF or stop engine to cool ATF.
3. Select "2ND GR FNCTN P0732" of "Utility (Readiness test / DTC work support)" mode for "AT" with SDT.
4. Drive vehicle and maintain the following conditions.
SLCT LVR POSI: "2" position
GEAR: "2" 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 SDT screen changes from "OUT OF CONDITION" to "TESTING".
CAUTION:
If "TESTING" does not appear on SDT for a long time, select "DTC check". In case a 1st trip DTC other than P0732 is shown, refer to [SDT Function (AT)]. Scan Tool Testing and Procedures
If "COMPLETED RESULT NG" is detected, go to [P0732 2Gr Incorrect Ratio].
If "STOP VEHICLE" is detected, go to the following step.
6. Stop vehicle.
7. Drive vehicle in "D" position allowing it to shift from 1GR to 5GR and check shift timing and shift shock.
^ Touch "OK" to complete the inspection when normally shifted from the 1GR to 5GR.
^ Touch "NG" when an unusual shift shock, etc. occurs in spite of shifting from the 1GR to 5GR. Go to [Road Test: Check Before Engine Is Started].
^ Perform [SDT Function (AT)] when not shifted from the 1GR to 5GR. (Neither "OK" nor "NG" are indicated.)
With GST
1. Start the engine.
2. Drive vehicle for approximately 5 minutes in urban areas.
3. Drive vehicle and maintain the following conditions for at least 5 consecutive seconds.
Selector lever: "2" position
Gear position: "2" position
Accelerator opening: 0.6/8 or more
Vehicle speed: 10 km/h (6 MPH) or more
4. Check DTC.
5. If DTC is detected, go to [P0732 2Gr Incorrect Ratio].
