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

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.
