Component Description
FUEL CUT SOLENOID VALVE
When the ignition switch is off, the ECM turns the fuel cut solenoid
valve OFF (under this condition, no current flows through the fuel
cut solenoid valve), shutting off fuel supply.
When the engine is not operating due to trouble, the fuel cut sole-
noid valve may or may not be OFF even when the ignition switch
is ON.

DTC Confirmation Procedure
NOTE:
If DTC P0115 or P0335 is displayed same time, perform trouble
diagnosis for P0115 or P0335 first.
WITH CONSULT-II
1) Turn ignition switch to ªONº position.
2) Select ªDATA MONITORº mode with CONSULT-II.
3) Start engine. (If no start, circuit is open.)
4) Warm it up sufficiently.
5) Turn ignition switch to ªLOCKº position, wait at least 5 seconds.
6) Start engine and rev it up to above 1,300 rpm. Release pedal
and wait at least 3 seconds.
WITHOUT CONSULT-II
1) Start engine. (If no start, circuit is open.)
2) Warm it up sufficiently.
3) Turn ignition switch to ªLOCKº position, wait at least 5 seconds.
4) Start engine and rev it up to above 1,300 rpm. Release pedaland wait at least 3 seconds.
5) Turn ignition switch to ªLOCKº position, wait at least 5 seconds and then turn to ªONº position.
6) Perform ªDiagnostic Test Mode IIº (Self-diagnostic results).

Diagnostic Procedure
INSPECTION START
CHECK POWER SUPPLY.
Check power supply.
CHECK OUTPUT SIGNAL CIRCUIT.
With CONSULT-II
1. Turn ignition switch to ªONº position.
2. Select ªFUEL CUT SOL/Vº in ªACTIVE TESTº mode with CONSULT-II.
3. Touch ªONº and ªOFFº alternately.
4. Check that operating sound is emitted.
Without CONSULT-II
1. Turn ignition switch to ªLOCKº position.
2. Disconnect ECM harness connector and TVC and shut-off harness connec-
tor.
3. Check harness continuity between TVC and shut-off harness connector termi-
nal q
8and ECM connector terminals
202, TVC and shut-off terminal q10
and ECM terminal349. Refer to wir-
ing diagram.
Continuity should exist.
If OK, check harness for short-circuit.
OK
ENG Repair harness or connec-
tors.
CHECK COMPONENT
[TVC and shut-off (Fuel cut solenoid
valve)].
Refer to ªCOMPONENT INSPECTIONº on
page EC-402.
OK
ENGReplace [TVC and shut-off
(fuel cut solenoid valve)].
Disconnect and reconnect harness con-
nectors in the circuit. Then retest.
Trouble is not fixed.
Check ECM pin terminals for damage and
check the connection of ECM harness
connector. Reconnect ECM harness con-
nector and retest.

Component Description
INJECTION TIMING CONTROL VALVE
The injection timing control valve is built into the fuel injection
pump. It controls the timer piston to change the fuel injection tim-
ing.
The timing control valve is a solenoid valve located in the line
between high-pressure chamber and low-pressure chamber. It
changes fuel pressure in the high-pressure chamber.
When current flows through the solenoid (the solenoid turns ON),
the timing control valve opens, advancing fuel injection timing.
When current does not flow through it, the timing control valve
closes, retarding injection timing.
The ECM emits an ON-OFF duty signal. The longer the OFF-
duration, the greater the advance angle. The longer the
ON-duration, the greater the retard angle. This means that chang-
ing the ON-OFF duty ratio makes it possible to achieve an optimal
advance angle and accurately control fuel injection timing.

DTC P1246 Confirmation Procedure
NOTE:
If both DTC P1246 and P1240 or P0335 are displayed, perform
TROUBLE DIAGNOSIS FOR DTC P1240 or P0335. (See EC-450
or EC-408.)
WITH CONSULT-II
1) Turn ignition switch to ªONº position and select ªDATA MONI-TORº mode with CONSULT-II.
2) Start engine. Run it for 10 seconds at idle.
WITHOUT CONSULT-II
1) Start engine. Run it for 10 seconds at idle.
2) Turn ignition switch to ªLOCKº position, wait at least 5 seconds and then turn to ªONº position.
3) Perform ªDiagnostic Test Mode IIº (Self-diagnostic results).
NOTE:
If a malfunction occurs intermittently, conduct suitable driving
pattern for 10 minutes. This makes it possible to determine
DTC.
