7. HYDRAULIC TEST
Measure the line pressure.
NOTICE:

Do the test at normal operation fluid temperature 50 ± 80 °C (122 ± 176 °F).

The line pressure test should always be carried out in pairs. One technician should observe
the conditions of wheels or wheel stoppers 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 transaxle case front left side and connect SST.
(See Pub. No. RM654U on page AX±17 for the location to connect SST)
SST 09992±00095 (09992±00231, 09992±00271)
(3) Fully apply the parking brake and chock the 4 wheels.
(4) Connect an OBD II scan tool or hand±held tester to DLC3.
(5) Start the engine and check idling speed.
(6) Keep your left foot pressing firmly on the brake pedal and shift into D position.
(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 manner, do the test in R position.
Specified line pressure:
ConditionD position kPa (kgf/cm2, psi)R position kPa (kgf/cm2, psi)

If the measured pressure is not up to the specified value, recheck the throttle cable adjustment and retest.

DTC P0770 Shift Solenoid E Malfunction
(Shift Solenoid Valve SL)
SYSTEM DESCRIPTION
The ECM uses the signals from the throttle position sensor, air±
flow meter and crankshaft position sensor to monitor the en-
gagement condition of the lock±up clutch.
Then the ECM compares the engagement condition of the
lock±up clutch with the lock±up schedule in the ECM memory
to detect mechanical trouble of the shift solenoid valve SL,
valve body, torque converter clutch or automatic transaxle
(clutch, brake or gear etc.).
DTC No.DTC Detecting ConditionTrouble Area
P0770

Lock±up does not occur when driving in the lock±up range
(normal driving at 80 km/h [50 mph]), or lock±up remains ON
in the lock±up OFF range.
(2 trip detection logic)

When lock±up is ON, clutch or brake slips or gear is broken.
Shift solenoid valve SL is stuck open or closed

Valve body blocked up or stuck

Lock±up clutch

Automatic transaxle (clutch, brake or gear etc.)
INSPECTION PROCEDURE
1 Check solenoid valve SL operation.
PREPARATION:
(a) Remove the oil pan.
(b) Remove the shift solenoid valve SL.
CHECK:
(a) By applying 490 kPa (5 kgf/cm2, 71 psi) of compressed
air, check that the solenoid valve does not leak air.
(b) When battery positive voltage is supplied to the shift sole-
noid valve, check that the solenoid valve opens.
OK:
(a) Solenoid valve does not leak air.
(b) Solenoid valve opens.
NG Replace the solenoid valve SL.
OK

COMPRESSION
INSPECTION
HINT:
If there is lack of power, excessive oil consumption or poor fuel
economy, measure the compression pressure.
1. WARM UP AND STOP ENGINE
Allow the engine to warm up to normal operating temperature.
2. DISCONNECT IGNITION COIL CONNECTORS
3. REMOVE SPARK PLUGS (See page IG±1)
4. INSPECT CYLINDER COMPRESSION PRESSURE
(a) Insert a compression gauge into the spark plug hole.
(b) Fully open the throttle.
(c) While cranking the engine, measure the compression
pressure.
HINT:
Always use a fully charged battery to obtain engine speed of
250 rpm or more.
(d) Repeat steps (a) through (c) for each cylinder.
NOTICE:
This measurement must be done in as short a time as pos-
sible.
Compression pressure:
1,226 kPa (12.5 kgf/cm
2, 178 psi) or more
Minimum pressure: 981 kPa (10.0 kgf/cm
2, 142 psi)
Difference between each cylinder:
98 kPa (1.0 kgf/cm
2, 14 psi) or less
(e) If the cylinder compression in one or more cylinders is low,
pour a small amount of engine oil into the cylinder through
the spark plug hole and repeat steps (a) through (c) for
cylinders with low compression.

If adding oil helps the compression, it is likely that
the piston rings and/or cylinder bore are worn or
damaged.

If pressure stays low, a valve may be sticking or
seating is improper, or there may be leakage past
the gasket.
5. REINSTALL SPARK PLUGS (See page IG±1)

NOTICE:

Support the timing belt, so the meshing of the crank-
shaft timing pulley and timing belt does not shift.

Be careful not to drop anything inside the timing belt
cover.

Do not allow the belt to come into contact with oil, wa-
ter or dust.
21. REMOVE ENGINE HANGERS AND GENERATOR
BRACKET
(a) Remove the 3 bolts, the generator bracket and RH engine
hanger assembly.
(b) Remove the bolt and LH engine hanger.
22. REMOVE OIL PRESSURE SWITCH
23. REMOVE CYLINDER HEAD COVER
Remove the 4 nuts, grommets, head cover and gasket.
HINT:
Arrange the grommets in the correct order, so that they can be
reinstalled into their original positions. This minimizes any pos-
sibility of oil leakage due to reuse of the grommets in different
positions.
24. REMOVE CAMSHAFTS
NOTICE:
Since the thrust clearance of the camshaft is small, the
camshaft must be kept level while it is being removed. If the
camshaft is not kept level, the portion of the cylinder head
receiving the shaft thrust may crack or be damaged, caus-
ing the camshaft to seize or break. To avoid this, the follow-
ing steps should be carried out.
(a) Remove the exhaust camshaft.
(1) Set the knock pin of the intake camshaft at 10 ± 45°
BTDC of camshaft angle.
HINT:
The above angle allows No.2 and No.4 cylinder cam lobes of
the exhaust camshaft to push their valve lifters evenly.
