INSPECTION
FUNCTION AND OPERATION PRICIPLE
Crankshaft Position Sensor (CKPS) detects the crankshaft position and is one of the most important sensors of the
engine control system. If there is no CKPS signal input, fuel is not supplied and the main relay does not operate. That
is, vehicle can't run without CKPS signal. This sensor is installed on transaxle housing and generates alternating
current by magnetic flux field which is made by the sensor and the target wheel when engine runs. The target wheel
consists of 58 slots and 2 missing slots on 360 CA (Crank Angle).

INSPECTION
FUNCTION AND OPERATION PRICIPLE
Camshaft Position Sensor (CMPS) is a hall sensor and detects the camshaft position by using a hall element. It is
related with Crankshaft Position Sensor (CKPS) and detects the piston position of each cylinder which the CKPS can't
detect. The two CMPS are installed on engine head cover of bank 1 and 2 and uses a target wheel installed on the
camshaft. This sensor has a hall - effect IC which output voltage changes when magnetic field is made on the IC with
current flow.

7 Selector lever position
: D (Carry out on a
flat and straight road)
a.
Accelerate to 4th gear at
a throttle position sensor
output of 1.5V
(accelerator opening
angle of 30 %).
b. Gently decelerate to a
standstill.
c. Accelerate to 4th gear at
a throttle position sensor
output of 2.5 V
(accelerator opening
angle of 50%).
d. While driving at 60 km/h
in 4th gear, shift down
to 3rd gear.
e. While driving at 40 km/h
in 3rd gear, shift down
to 2nd gear.
f. While driving at 20 km/h
in 2nd gear, shift down
to 1st gear. For (1), (2) and (3),
the reading should be
the same as the
specified output shaft
torque, and no
abnormal shocks
should occur.
For (4), (5) and (6),
downshifting should
occur immediately
after the shifting
operation is made.

when reversing.Does not shift
TORQUE CONVERTER STALL TEST
This test measures the maximum engine speed when the selector lever is in the D or R position. The torque converter
stalls to test the operation of the torque converter, starter motor, one- way clutch operation, the holding performance of
the clutches, and brakes in the transaxle.
Do not let anybody stand in front of or behind the vehicle while this test is being carried out
1. Check the automatic transmission fluid level and temperature, and the engine coolant temperature.
a. Fluid level : At the HOT mark on the oil level gauge
b. Fluid temperature : 80~100°C (176~212°F)
c. Engine coolant temperature : 80~100°C(176~212°F)
2. Prevent all the wheels from moving during the test.
3. Pull the parking brake lever up, with the brake pedal fully depressed.
4. Start the engine.

5.Move the selector lever to the "D" position, fully depress the accelerator pedal and take a reading of the maximum
engine speed at this time.
Stall speed : 2,100~2,900rpm
a.The throttle should not be left fully open for any more than five seconds.
b. If carrying out the stall test two or more times, move the selector lever to the "N" position and run the
engine at 1,000 r/min to let the automatic transaxle fluid cool down before carrying out subsequent tests.
6. Move the selector lever to the "R" position and carry out the same test again.
TORQUE CONVERTER STALL TEST CONCLUSION
1.Stall speed is too high in both "D" and "R" ranges
a. Low line pressure
b. Low & reverse brake(B) slippage
2. Stall speed is to high in "D" range only
a. Underdrive clutch(C) slippage
3. Stall speed is too high in "R" range only
a. Reverse clutch(A) slippage
4. Stall speed too low in both "D" and "R" ranges
a. Malfunction of torque converter(D)
b. Insufficient engine output
HYDRAULIC PRESSURE TEST
1.Warm up the engine until the automatic transaxle fluid temperature is 80- 100°C.
2. Lift up the vehicle so that the wheels are free to turn.
3. Connect the special tool (oil pressure gauge) to each pressure discharge port.
4. Measure the hydraulic pressure at each port under the conditions given in the standard hydraulic pressure table,
and check that the measured values are within the standard value ranges.
5. If a value is outside the standard range, correct the problem while referring to the hydraulic pressure test diagnosis
table.
