DTC P0770 SHIFT SOLENOID ºEº 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 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 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.
(2±trip detection logic)
Shift solenoid valve SL is stuck open or closed

Valve body blocked or stuck

Shift solenoid valve SL

Torque converter clutch

Automatic transaxle (clutch, brake or gear etc.)
INSPECTION PROCEDURE
1 INSPECT SHIFT SOLENOID VALVE(SL)
(a) Remove the shift solenoid valve SL.
(b) Measure the resistance between terminal SL of shift sole-
noid valve and the solenoid valve body.
OK:
Resistance: 11 to 15
at 20C (68F)
(c) Connect the positive (+) lead to the terminal of solenoid
valve connector and the negative (±) lead to the solenoid
valve body.
OK:
The solenoid valve makes an operating noise.
NG REPLACE SHIFT SOLENOID VALVE(SL)
OK

DTC P0750 SHIFT SOLENOID ºAº MALFUNCTION
(SHIFT SOLENOID VALVE S1)
DTC P0755 SHIFT SOLENOID ºBº MALFUNCTION
(SHIFT SOLENOID VALVE S2)
SYSTEM DESCRIPTION
The ECM uses signals from the vehicle speed sensor and speed sensor NT 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 the mechanical
trouble of the shift solenoid valves, the valve body or automatic transaxle (clutch, brake or gear etc.).

PROBLEM SYMPTOMS TABLE
HINT:
If a normal code is displayed during the DTC check but the trouble still o\
ccurs, check the circuits for each
symptom in the order given in the charts on the following pages and proceed to \
the page given for trouble-
shooting.
The Matrix Chart is divided into 3 chapters.

If the instruction ºProceed to next circuit inspection shown on matri\
x chartº is given in the flow chart
for each circuit, proceed to the circuit with the next highest number in the table to continue the check.

If the trouble still occurs even though there are no abnormalities in any of the other circuits, then ch\
eck
and replace the ECM.
