Gear position during fail-safe operation:
If any malfunction is detected, the ECM changes into the fail-safe mode to shift into the gear positions as shown
in the table below.

MONITOR DESCRIPTION
The ECM commands gear shifts by turning the shift solenoid valves "ON/OFF" and switching oil pressure to
the valves in the valve body.
The DTC indicates that the reverse sequence valve is locked in the direction the spring stretches and that
shifting to the 6th gear is impossible.

The ECM commands gear shifts by turning the shift solenoid valves "ON/OFF" and switching oil pressure to
the valves in the valve body.
The ECM calculates the "actual" transmission gear by comparing the signals from the input speed sensor (NT)
and the output speed sensor (SP2). The ECM can detect many mechanical problems in the shift solenoids, valve
body, and the transmission clutches, brakes, and gears. If the ECM detects that the actual gear position and the
commanded gear position are different, it will illuminate the MIL and store the DTC.

3.INSPECT EVAPORATIVE EMISSION CONTROL SYSTEM
a. Start the engine. Disconnect the vacuum hose as shown in the illustration.
b. From the hand-held tester ACTIVE TEST mode, select PURGE VSV. Check that a vacuum occurs
at the VSV port.
c. Exit ACTIVE TEST mode and reconnect the vacuum hose.
d. From the hand-held tester ECU DATA MONITOR mode, select PURGE VSV. Check operation of
the purge VSV.
e. Warm up the engine and drive the vehicle. Confirm that the purge VSV is turned from OFF to ON.

4.VISUALLY INSPECT HOSES, CONNECTIONS AND GASKETS
a. Check for cracks, leaks or damage.
HINT:
Possible leakage points are indicated in the illustration.
Removal or problems with the engine oil dipstick, filler cap, PCV hose and other components may
cause the engine to run improperly. Disconnection, looseness or cracks in the parts of the air
induction system between the throttle body and cylinder head will allow air suction and cause the
engine trouble.
