DTC P0746 PRESSURE CONTROL SOLENOID ºAº
PERFORMANCE (SHIFT SOLENOID VALVE
SL1)
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
problems of the shift solenoid valves and valve body.
DTC No.DTC Detecting ConditionTrouble Area
P0746The gear required by the ECM does not match the actual gear
when driving (2-trip detection logic)

Shift solenoid valve SL1 remains open or closed

Valve body is blocked

Shift solenoid valve SL1

Automatic transaxle (clutch, brake or gear etc.)

ECM
MONITOR DESCRIPTION
The ECM commands gear shifts by turning the shift solenoid valves ºON/OFFº. According to the input shaft
revolution, intermediate (counter) shaft revolution and output shaft revolution, the ECM detects the actual
gear position (1st, 2nd, 3rd or O/D gear position). When the gear position commanded by the ECM and the
actual gear position are not same, the ECM illuminates the MIL.
Example:
When either condition (a) or (b) is met, the ECM detects a malfunction.
(a) The ECM commands the 1st gear, but the actual gear is 2nd.
(b) The ECM commands the 2nd gear, but the actual gear is 1st.

INSPECTION PROCEDURE
HINT:
Read freeze frame data using the hand-held tester or the OBD II scan tool. Freeze frame data records the
engine conditions when a malfunction is detected. When troubleshooting, freeze frame data can help deter-
mine if the vehicle was running or stopped, if the engine was warmed up or not, if the air-fuel ratio was lean
or rich, and other data from the time the malfunction occurred.
1 CHECK OTHER DTC OUTPUT (IN ADDITION TO DTC P2119)
Display (DTC output)Proceed to
Only P2119 is outputA
P2119 and other codes are outputB
B GO TO RELEVANT DTC CHART (See page

2 CHECK IF DTC OUTPUT REOCCURS
(a) Clear the DTC (see page 05-38).
(b) Allow the engine to idle for 15 seconds.
(c) Pull the hand brake and shift the gear to D.
(d) Depress the brake pedal securely and the accelerator pedal fully for 5 seconds.
(e) Read the DTC.
HINT:
Actual throttle position (TP) sensor voltage can be confirmed using the hand-held tester [DATA LIST / ALL
/ THROTTLE POS #1].
OK: No DTC is output.

DTC P0741 TORQUE CONVERTER CLUTCH SOLENOID
PERFORMANCE (SHIFT SOLENOID VALVE
DSL)
SYSTEM DESCRIPTION
The ECM uses the signals from the throttle position sensor, Air-flow meter, turbine (input) speed sensor,
intermediate (counter) shaft speed sensor and crankshaft position sensor to monitor the engagement condi-
tion 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 a mechanical problems of the shift solenoid valve DSL, valve body and torque con-
verter clutch.
DTC No.DTC Detection ConditionTrouble Area
P0741
Lock-up does not occur when driving in lock-up range (normal
driving at 85 km/h [53 mph]), or lock-up remains ON in lock-
up OFF range (2-trip detection logic)

Shift solenoid valve DSL remains open or closed

Valve body is blocked

Shift solenoid valve DSL

Torque converter clutch

Automatic transaxle (clutch, brake or gear etc.)

Line pressure is too low

ECM
MONITOR DESCRIPTION
Torque converter lock-up is controlled by the ECM based on speed sensor (NT), speed sensor (NC), engine
rpm, engine load, engine temperature, vehicle speed, transmission temperature, and gear selection. The
ECM determines the lock-up status of the torque converter by comparing the engine rpm (NE) to the input
turbine rpm (NT). The ECM calculates the actual transmission gear by comparing input turbine rpm (NT) to
counter gear rpm (NC). When conditions are appropriate, the ECM requests ºlock-upº by applying control
voltage to shift solenoid DSL. When the DSL is turned on, solenoid DSL applies pressure to the lock-up relay
valve and locks the torque converter clutch.
If the ECM detects no lock-up after lock-up has been requested or if it detects lock-up when it is not re-
quested, the ECM interprets this as a fault in the shift solenoid valve DSL or lock-up system performance.
The ECM will turn on the MIL and store the DTC.
Example:
When any of the following is met, the system judges it as a malfunction.
(a) There is a difference in rotation between before and after torque converters even when the ECM com-
mands lock-up.
(Engine speed is at least 75 rpm greater than input turbine speed.)
(b) There is no difference in rotation between before and after torque converters even when the ECM com-
mands lock-up off.
(The difference between engine speed and input turbine speed is less than 35 rpm.)
