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.

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.
