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). The ECM then compares the actual gear with the shift schedule in the ECM memory to detect mechan-
ical trouble of the shift solenoid valves and valve body.
DTC No.DTC Detecting ConditionTrouble Area
P0750
P0755During normal driving, gear required by the 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 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 valves do not leak air.
(b) When battery positive voltage is supplied to the solenoid
valves, check that solenoid valve open.
NG Replace shift solenoid valve No. 1 or No. 2.
OK
2 Check valve body (See page DI−192).
NG Repair or replace valve body.
OK
Repair or replace transaxle (See page
AX−19).

DTC P0770 Shift Solenoid E Malfunction
(Shift Solenoid Valve SL)
SYSTEM DESCRIPTION
The ECM uses the signals from the throttle position sensor and
air flow meter 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.
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)Shift solenoid valve SL is stuck open or closed
Valve body blocked up or stuck
Lock−up clutch
INSPECTION PROCEDURE
1 Check shift solenoid valve SL operation.
PREPARATION:
Remove the shift solenoid valve SL from the valve body.
CHECK:
(a) Applying 490 kPa (5 kgf/cm2, 71 psi) of compressed air,
check that the solenoid valve open.
(b) When battery positive voltage is supplied to the solenoid
valve, check that solenoid valve does not leak air.
NG Replace shift solenoid valve SL.

INSPECTION PROCEDURE
1 Check shift solenoid valve SLD.
Check solenoid resistance:
PREPARATION:
(a) Jack up the vehicle.
(b) Remove the oil pan.
(c) Disconnect the connector.

noid connector.
OK:
Resistance: 5.1 − 5.5 Ω
Check solenoid operation:
CHECK:
Connect positive lead with an 8 − 10 W bulb to terminal 1 of
the solenoid connector and nagative lead to terminal 2, then
check the movement of the valve.
OK:
When battery positive voltage is appliedValve moves in → direction in illumina-
tion (on the left)

When 2 or more codes are indicated, the lowest numbered code will be displayed first.
If the inspection ”Proceed to next circuit inspection shown on matrix chart” is given in the flow chart
for each circuit, proceed to the circuit with the next highest number in the table to continue check.
If the trouble still reappears even though there are no abnormalities in any of the other circuits, then
check or replace the cruise control ECU as the last step.
(*) When the vehicle speed decrease on uphill roads, the speed can be set again and driving continued. (This
is not a malfunction.)
