P0732 2GR INCORRECT RATIO
DescriptionINFOID:0000000005928148
• This malfunction will not be detected while the OD OFF indicator lamp is indicating another self-diagnosismalfunction.
• This malfunction is detected when the A/T does not shif t into second gear position as instructed by the TCM.
This is not caused by electrical malfunction (circuit s open or shorted) but by mechanical malfunction such as
control valve sticking, improper solenoid valve operation, etc.
On Board Diagn osis LogicINFOID:0000000005928149
• This is an OBD-II self-diagnostic item.
• Diagnostic trouble code “P0732 2GR INCORRECT RATIO” with CONSULT-III is detected when A/T cannot
be shifted to the 2GR position even if electrical circuit is good.
• This diagnosis monitors actual gear position by checki ng the torque converter slip ratio calculated by TCM
as follows:
Torque converter slip ratio = A x C/B
A: Output shaft revolution signal from output speed 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 specif ied value, TCM judges this diagnosis malfunction.
This malfunction will be caused when 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 B stuck open: 4, 3*, 3 and 4 positions to each gear position
above
*: “P0732 2GR INCORRECT RATIO” is detected.
Possible CauseINFOID:0000000005928150
• Shift solenoid valve B
• Each clutch
• Hydraulic control circuit
DTC Confirmation ProcedureINFOID:0000000005928151
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 proc edure to confirm the malfunction is eliminated.
WITH CONSULT-III
1. Start engine and select “DATA MONITOR” m ode for “TRANSMISSION” 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 - 1.5 V
If out of range, drive the vehicle to decrease the vo ltage (warm up the fluid) or stop engine to increase the
voltage (cool down the fluid).
4. Select “2ND GR FNCTN P0732” of “DTC & SR T CONFIRMATION” mode for “TRANSMISSION” with
CONSULT-III and touch “START”.
5. Accelerate vehicle to 45 to 50 km/h (28 to 31 MPH) under the following conditions and release the accel- erator pedal completely.

• The torque converter clutch solenoid valve is activated, with the gear in D4 and D3, by the TCM in response
to signals sent from the output speed sensor and t he ECM (throttle opening). Lock-up piston operation will
then be controlled.
• Lock-up operation, however, is prohibited when A/T fluid temperature is too low.
• When the accelerator pedal is depressed (less than 2/8) on lock-up condition, the engine speed should not
change abruptly. If there is an abrupt change in engine speed, there is no lock-up.
