DescriptionNJAT0287+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 indi-
cator lamp is indicating another self-diagnosis malfunction.
+This malfunction is detected when the A/T does not shift into
third 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, malfunctioning servo piston
or brake band, etc.

ON BOARD DIAGNOSTIC LOGICNJAT0287S02This 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 (3rd) supposed
by TCM, the slip ratio will be more than normal. In case the ratio
exceeds the specified value, TCM judges this diagnosis malfunc-
tion.
This malfunction will be caused when shift solenoid valve A is stuck
closed.

DIAGNOSTIC TROUBLE CODE (DTC) CONFIRMATION
PROCEDURE
NJAT0287S03CAUTION:
+Always drive vehicle at a safe speed.
+Be careful not to rev engine into the red zone on the
tachometer.
NOTE:
If ªDIAGNOSTIC TROUBLE CODE CONFIRMATION PROCE-
DUREº has been previously conducted, always turn ignition
switch ªOFFº 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 ªDATA MONITORº mode for ªA/Tº 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 ª3RD GR FNCTN P0733º of ªDTC WORK SUPPORTº
mode for ªA/Tº with CONSULT-II and touch ªSTARTº.
4) Accelerate vehicle to 70 to 85 km/h (43 to 53 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 ªONº)
+Check that ªGEARº shows ª4º after releasing pedal.
5) Depress accelerator pedal steadily with 3.5/8 - 4.5/8 of
ªTHROTTLE POSIº from a speed of 70 to 85 km/h (43 to 53
MPH) until ªTESTINGº changes to ªSTOP VEHICLEº or ªCOM-
PLETEDº. (It will take approximately 3 seconds.)
If the check result NG appears on CONSULT-II screen, go to
ªDIAGNOSTIC PROCEDUREº, AT-219.
If ªSTOP VEHICLEº appears on CONSULT-II screen, go to
following step.
+Check that ªGEARº shows ª3º when depressing accelera-
tor pedal with 3.5/8 - 4.5/8 of ªTHROTTLE POSIº.
+If ªTESTINGº does not appear on CONSULT-II for a long
time, select ªSELF-DIAGNOSISº for ªENGINEº. In case a
1st trip DTC other than P0733 is shown, refer to applicable
ªTROUBLE DIAGNOSIS FOR DTCº.
6) Stop vehicle.
7) Follow the instruction displayed. (Check for normal shifting
referring to the table below.)

self-diagnosis.
+This malfunction will not be detected while the O/D OFF indi-

+This malfunction is detected when the A/T does not shift into
fourth gear position or the torque converter clutch does not
lock up as instructed by the TCM. This is not caused by elec-
trical malfunction (circuits open or shorted) but by mechanical
malfunction such as control valve sticking, improper solenoid
valve operation, malfunctioning oil pump or torque converter
clutch, etc.
