DIAGNOSTIC TROUBLE CODE CHART
If a DTC is displayed during the DTC check, check the parts listed in the \
table below and proceed to the page
given.
HINT:

*1 :  ... MIL (Malfunction Indicator Lamp) light up

*2 : ’’ ’’ mark means ECM memorizes the malfunction code if the ECM detects the DT\
C detection
condition.

This DTC may be output when the clutch, brake and gear components etc. inside\
the automatic trans-
axle are damaged.
DTC No.

DTC P0751 SHIFT SOLENOID ”A” PERFORMANCE
(SHIFT SOLENOID VALVE S1)
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 4th 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
P0751The gear required by the ECM does not match the actual gear
when driving (2–trip detection logic)

Shift solenoid valve S1 remains open or closed

Valve body is blocked

Shift solenoid valve S1

Automatic transaxle (clutch, brake or gear etc.)

ECM
MONITOR DESCRIPTION
The ECM commands gear shifts by turning the shift solenoid valves ”ON/OFF”. 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 4th 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:
Using the Intelligent Tester II Data List allows switch, sensor, actuator and other item values to be read with-
out removing any parts. Reading the Data List early in troubleshooting is one way to shorten labor time.
NOTICE:
In the table below, the values listed under ”Normal Condition” are reference values. Do not depend
solely on these reference values when deciding whether a part is faulty or not.
(a) Warm up the engine.
(b) Turn the ignition switch off.
(c) Connect the Intelligent Tester II to the DLC3.
(d) Turn the ignition switch to the ON position.
(e) Turn on the tester.
(f) Select the item ”Enter / Power train / Engine and ECT / Data List”.
(g) Follow the instructions on the tester and read the Data List.
