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 and direct clutch 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, valve body or automatic transaxle (clutch, brake or gear etc.)

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 valve opens.
NG Replace the shift solenoid valve No.1 or No.2.

DTC P0753, P0758 Shift Solenoid A/B Electrical Malfunc-
tion (Shift Solenoid Valve No.1/No.2)
CIRCUIT DESCRIPTION
Shifting from 1st to O/D is performed in combination with ON and OFF of the shift solenoid valves No.1 and
No.2 controlled by ECM. If an open or short circuit occurs in either of the shift solenoid valves, the ECM con-
trols the remaining normal shift solenoid valve to allow the vehicle to be operated smoothly (Fail safe func-
tion).
Fail Safe Function:
If either of the shift solenoid valve circuits develops an open or short, the ECM turns the other shift solenoid
ON and OFF to shift to the gear positions shown in the table below. The ECM also turns the shift solenoid
valve SL OFF at the same time. If both solenoids are malfunction, hydraulic control cannot be performed
electronically and must be done manually.
Manual shifting as shown in the following table must be done (In the case of a short circuit, the ECM stops
sending current to the short circuited solenoid).
Check the shift solenoid valve No.1 when DTC P0753 is output and check the shift solenoid valve No.2 when
DTC P0758 is output.
DTC No.DTC Detecting ConditionTrouble Area
P0753
P0758
The ECM checks for an open or short circuit in the shift sole-
noid valves No.1 and No.2 circuit when it changes.
The ECM records DTC P0753 or P0758 if condition (a) or (b) is
detected once, but it does not light up MIL.
After ECM detects condition (a) or (b) continuously 8 times or
more in a trip and the MIL light up.
(a) When the solenoid is energized, the solenoid resistance
is 8 W or less and is counted.
(b) When the solenoid is not energized, the solenoid resistance
is 100 kW or more and is counted.

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

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) 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.
