DTC P0750, P0755 Shift Solenoid A/B Malfunction (Shift
Solenoid Valve No.1/No.2)
SYSTEM DESCRIPTION
The ECM uses signals from the vehicle speed sensor to detect the actual gear position (1st, 2nd, 3rd or O/D
gear).
Then the ECM compares the actual gear with the shift schedule in the ECM memory to detect mechanical
trouble of the shift solenoid valves and valve body.
DTC No.DTC Detecting ConditionTrouble Area
P0750
P0755During normal driving, gear required by ECM does not match
actual gear
(2 trip detection logic)Shift solenoid valve No.1/No.2 is stuck open or closed
Valve body is blocked up or stuck
HINT:
Check the shift solenoid valve No.1 when DTC P0750 is output and check shift solenoid valve No.2 when
DTC P0755 is output.
INSPECTION PROCEDURE
1 Check shift solenoid valve No.1 or No.2 operation.
PREPARATION:
(a) Remove the oil pan.
(b) Remove the shift solenoid valve No.1 or No.2.
CHECK:
(a) 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.
NG Replace shift solenoid valve No.1 or No.2.
OK
2 Check valve body (See page DI−282).
NG Repair or replace valve body.
OK
Repair or replace transmission (See page

DTC P0770 Shift Solenoid E Malfunction
(Shift Solenoid Valve SL)
SYSTEM DESCRIPTION
The ECM uses the signals from the Throttle position sensor,
mass air flow meter and crankshaft position sensor to monitor
the engagement 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 and torque converter clutch.

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

Valve body blocked up or stuck
Lock−up clutch
INSPECTION PROCEDURE

DTC 31 − 36 Speed Sensor Circuit
CIRCUIT DESCRIPTION
The speed sensor detects wheel speed and sends the ap-
propriate signals to the ECU. These signals are used to control
the ABS system. The front and rear rotors each have 48 serra-
tions.
When the rotors rotate, the magnetic field emitted by the perma-
nent magnet in the speed sensor generates an AC voltage.
Since the frequency of this AC voltage changes in direct propor-
tion to the speed of the rotor, the frequency is used by the ECU
to detect the speed of each wheel.

DTC No.DTC Detecting ConditionTrouble Area
31, 32, 33, 34
Detection of any of conditions 1 through 3:
1. At vehicle speed of 10 km/h (6 mph) or more, pulses are
not input for 15 sec.
2. Momentary interruption of speed sensor signal occurs at
least 7 times in time between switching the ignition
switch ON and switching it OFF.
3. Abnormal fluctuation of speed sensor signals with ve-
hicle speed 20 km/h (12 mph) or more.
4. An open is detected in speed sensor circuit for 0.6 sec.

HINT:
DTC No. 31 is for the right front speed sensor.
DTC No. 32 is for the left front speed sensor.
DTC No. 33 is for the right rear speed sensor.
DTC No. 34 is for the left rear speed sensor.
Fail safe function:
If trouble occurs in the speed sensor circuit, the ECU cuts off current to the ABS control (solenoid) relay and
prohibits ABS control.

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
2. REMOVE INTAKE AIR CONNECTOR
(See page EM−65)
3. DISCONNECT HIGH−TENSION CORDS FROM
SPARK PLUGS
NOTICE:
Pulling on or bending the cords may damage the conductor
inside.
4. REMOVE SPARK PLUGS
5. CHECK 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:
1,230 kPa (12.5 kgf/cm
2, 178 psi) or more
Minimum pressure:
880 kPa (9.0 kgf/cm
2, 127 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, chances are
that the piston rings and/or cylinder bore are worn
or damage.
If pressure stays low, a valve may be sticking or
seating is improper, or there may be leakage past
the gasket.
