When THW greater than ±40 \fC (±40 \fF) and less than 60 \fC
(140 \fF), and THA greater than ±6.7 \fC (20 \fF), and when start-
ing engine, conditions (a) and (b) continue (2 trip detection

In case that reading value of engine coolant temp. sensor will
not change more than 1 \fC (1.8 \fF) even after repeating 6 trips
(detection logic) of adjusting speed pattern with THW more
than 90 \fC (194 \fF) after engine was started.
INSPECTION PROCEDURE
HINT:

If DTCs ºP0115, P0116, P0117and P0118º are output simultaneously, engine coolant temperature
sensor circuit may be open or short. Perform the troubleshooting of DTC ºP0\
115, P0117 or P0118º first.

Read freeze frame data using \b
 . Freeze frame data records the engine conditions
when a malfunction is detected. When troubleshooting, it is useful for d\
etermining whether the vehicle
was running or stopped, the engine was warmed up or not, the air±fuel ra\
tio was lean or rich, etc. at
the time of the malfunction.
1CHECK OTHER DTC OUTPUT(BESIDES DTC P0116)
(a)Read the DTC using the hand±held tester. Result:

P0116 and other DTCs are outputB
HINT:
If any other codes besides ºP0116º are output, perform the troubleshooting for those DTCs first.

MONITOR DESCRIPTION
P0093 (Fuel leaks in high±pressure area):
This DTC stands for fuel leaks is existing in high±pressure area in the c\
ommon rail system. The ECM
constantly monitors the internal fuel pressure of the common rail after the engine is started, and the ECM
then will set this DTC if the decreasing rate of the internal fuel press\
ure is large when injecting the fuel.
In the common rail system, high±pressure fuel (approx. 30 to 180 MPa (\
306 to 1,835 kgf/cm
2, 4.351 to
26,106 psi)) is always applied to the high±pressure area including the su\
pply pump, common rail, injector
and piping. The ECM adjusts the suction control valve opening angle to obtain the target internal fuel pres-
sure.
If this DTC is present, the ECM enters fail±safe mode and permits drivi\
ng the vehicle for extra 1 minute before
stopping both the fuel injection and supply pump operation, then stops the engine\
. The fail±safe mode will
continue until the ignition switch is turned OFF.

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.

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
