DTC P0732 A/T 2ND GEAR FUNCTION
PFP:31940
Description
ECS0097T
●
This is an OBD-II self-diagnostic item and not available in TCM self-diagnosis.
●
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 second 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.
TCM TERMINALS AND REFERENCE VALUE
Remarks: Specification data are reference values.
ON BOARD DIAGNOSTIC LOGIC
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 (2nd) 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 shift solenoid valve B is stuck open.
*: P0732 is detected.

DTC P0732 A/T 2ND GEAR FUNCTION
DIAGNOSTIC TROUBLE CODE (DTC) CONFIRMATION PROCEDURE
CAUTION:
●
Always drive vehicle at a safe speed.
●
Be careful not to rev engine into the red zone on the tachometer.
NOTE:
If “DIAGNOSTIC TROUBLE CODE 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.
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 “2ND GR FNCTN P0732” of “DTC WORK SUPPORT”
mode for “A/T” with CONSULT-II and touch “START”.
4.
Accelerate vehicle to 35 to 40 km/h (22 to 25 MPH) under the
following condition and release the accelerator pedal com-
pletely.
THROTTLE POSI: Less than 1.0/8 (at all times during step 4)
Selector lever: D position (OD “ON”)
●
Check that “GEAR” shows “3” or “4” after releasing pedal.
5.
Depress accelerator pedal to WOT (more than 7.0/8 of “THROTTLE POSI”) quickly from a speed of 35 to
40 km/h (22 to 25 MPH) until “TESTING” changes to “STOP VEHICLE” or “COMPLETED”. (It will take
approximately 3 seconds.)
If the check result NG appears on CONSULT-II screen, go to
AT-145, "Diagnostic Procedure"
.
If “STOP VEHICLE” appears on CONSULT-II screen, go to following step.
●
Check that “GEAR” shows “2” 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 P0732 is shown, refer to applicable “TROUBLE DIAG-
NOSIS FOR DTC”.
