INSPECTION PROCEDURE
HINT:

If P0200 and P1271 are present simultaneously, there is open in the INJF wire harness between the
EDU and ECM, or there is open in the wire harness for both of the injector the pressure discharge valve.

Read freeze frame data using   
 . Freeze frame data records the engine conditions
when a malfunction is detected. When troubleshooting, it is useful for determining whether the vehicle
was running or stopped, the engine was warmed up or not, etc. at the time of the malfunction.
1 CHECK OTHER DTC OUTPUT(BESIDES DTC P0200)
(a) Connect the hand±held tester to the DLC3.
(b) Turn the ignition switch ON and push the hand±held tester main switch ON.
(c) Select the item ºDIAGNOSIS / OBD/MOBD / DTC INFO / CURRENT CODESº.
(d) Read the DTCs.

QUANTIFY BETWEEN CYLINDERS)
(a) Connect the hand±held tester to the DLC3.
(b) Turn the ignition switch ON and push the hand±held tester main switch ON.
(c) Start the engine.
(d) Select the item ºDIAGNOSIS / OBD/MOBD / DATA LIST / ALL / INJ VOLUME FBº and read its value
displayed on the hand±held tester.

5.SPEED SENSOR SIGNAL CHECK
HINT:
If the ignition switch is turned from ON to ACC or LOCK during
the test mode, the DTCs of the sensor check function will be
erased.
(a)Check the sensor signal.(1)Start the engine.
(2)Connect the hand±held tester to the DLC3.
(3)Select the TEST MODE.
(4)Check that the ABS warning light blinks.
HINT:
If the ABS warning light does not blink, inspect the ABS warning
light circuit (See page 05±737). (5) Drive the vehicle straight forward.
HINT:

Drive the vehicle faster than 45 km/h (28 mph) for several
sec.

There is a case that the sensor check is not completed if
the vehicle has its wheels spun or its steering wheel
steered during this check.
(6) Stop the vehicle.
(7) Using SST, connect the terminals Tc and CG of the DLC3.
(b) Read the DTC from the hand±held tester screen.
HINT:

See the list of DTCs shown on the 05±704.

Please refer to the hand±held tester operator's manual
for further details.

PROBLEM SYMPTOMS TABLE
HINT:
If a normal code is displayed during the DTC check but the trouble still o\
ccurs, check the circuits for each
symptom in the order given in the charts on the following pages and proceed to \
the page given for trouble-
shooting.
The Matrix Chart is divided into 3 chapters.

If the instruction ºProceed to next circuit inspection shown on matri\
x chartº is given in the flow chart
for each circuit, proceed to the circuit with the next highest number in the table to continue the check.

If the trouble still occurs even though there are no abnormalities in any of the other circuits, then ch\
eck

8. MECHANICAL SYSTEM TESTS
(a) Measure the stall speed.
The object of this test is to check the overall performance of the transaxle and engine by measuring
the stall speeds in the D and R ranges.
NOTICE:

Do the test at normal operating ATF temperature 50 to 80
C (122 to 176
F).

Do not continuously run this test for longer than 5 seconds.

To ensure safety, do this test in a wide, clear level area which provides good traction.

The stall test should always be carried out in pairs. One technician should observe the condi-
tions of wheels or wheel stoppers outside the vehicle while the other is doing the test.
(1) Chock the 4 wheels.
(2) Connect the hand±held tester to DLC3 or tachome-
ter to terminal TAC of DLC3 with SST.
SST 09843±18030
(3) Fully apply the parking brake.
(4) Keep your left foot pressing firmly on the brake ped-
al.
(5) Start the engine.
(6) Shift into the D range. Press all the way down on the
accelerator pedal with your right foot.
(7) Quickly read the stall speed at this time.
Stall speed: 2,550
150 rpm
(8) Do the same test in the R range.
Stall speed: 2,550
150 rpm
Evaluation:
ProblemPossible cause
(a) Stall speed low in D and R ranges

Engine output may be insufficient

Stator one±way clutch not operating properly
HINT: If more than 600 rpm below the specified value, the torque
converter could be faulty.
(b) Stall speed high in D range

Line pressure too low

Forward clutch slipping

No. 2 one±way clutch not operating properly

U/D clutch slipping
(c) Stall speed high in R range

Line pressure too low

Direct clutch slipping

1st & reverse brake slipping

U/D clutch slipping
(d) Stall speed high in D and R ranges

Line pressure too low

Improper fluid level

U/D one±way clutch not operating properly

(b) Measure the time lag.
(1) When the shift lever is shifted while the engine is idling, there will be a certain time lapse or lag
before the shock can be felt. This is used for checking the condition of the direct clutch, forward
clutch, and 1st and reverse brake.
NOTICE:

Do the test at normal operating ATF temperature 50 to 80
C (122 to 176
F).

Be sure to allow 1 minute interval between tests.

Take 3 measurements and take the average value.
(2) Chock the 4 wheels.
(3) Connect the hand±held tester to DLC3 or tachome-
ter to terminal TAC of DLC3 with SST.
SST 09843±18030
(4) Start engine and check idle speed.
Idle speed: 650  50 rpm (In N range and A/C OFF)
(5) Shift the lever from N to D range. Using a stop
watch, measure the time from when the lever is
shifted until the shock is felt.
Time lag: N
D less than 1.2 seconds
(6) In the same way, measure the time lag for N
R.
Time lag: N
R less than 1.5 seconds
Evaluation (If N
D or N
R time lag is longer than the specified):
ProblemPossible cause
N
D time lag is longer

Line pressure too low

Forward clutch worn

U/D one±way clutch not operating properly

9. HYDRAULIC TEST
(a) Measure the line pressure.
NOTICE:

Do the test at normal operation ATF temperature 50 to 80
C (122 to 176
F).

The line pressure test should always be carried out in pairs. One technician should observe
the conditions of wheels or wheel stopper outside the vehicle while the other is doing the test.

Be careful to prevent SST's hose from interfering with the exhaust pipe.
(1) Warm up the ATF.
(2) Remove the test plug on the rear side of the trans-
axle case and connect SST.
SST 09992±00095 (09992± 00231, 09992±00271)
(3) Fully apply the parking brake and chock the 4
wheels.
(4) Connect the hand±held tester to DLC3.
(5) Start the engine and check idling speed.
(6) Keep your left foot pressing firmly on the brake ped-
al and shift into D range.
(7) Measure the line pressure when the engine is idling.
(8) Depress the accelerator pedal all the way down.
Quickly read the highest line pressure when engine
speed reaches stall speed.
(9) In the same way, do the test in R range.
Specified line pressure:
ConditionD range kPa (kgf / cm2, psi)R range kPa (kgf / cm2, psi)
