Diagnostic Procedure
INSPECTION START
CHECK POWER SUPPLY.
Check power supply.
CHECK OUTPUT SIGNAL CIRCUIT.
With CONSULT-II
1. Turn ignition switch to “ON” position.
2. Select “FUEL CUT SOL/V” in “ACTIVE
TEST” mode with CONSULT-II.
3. Touch “ON” and “OFF” alternately.
4. Check that operating sound is emitted.
Without CONSULT-II
1. Turn ignition switch to “LOCK” 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

, TVC and shut-off terminal
q

and
ECM terminal

. Refer to wiring
diagram.
Continuity should exist.
If OK, check harness for short-circuit.
OK
E
NG
Repair harness or connec-
tors.
CHECK COMPONENT
[TVC and shut-off (Fuel cut solenoid
valve)].
Refer to “COMPONENT INSPECTION” on
page EC-379.
OK
E
NG
Replace [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 Inspection
[TVC AND SHUT OFF (FUEL CUT SOLENOID VALVE)]
1. Remove TVC and shut-off (fuel cut solenoid valve) harness
connector.
2. Check that operating sound is emitted when applying 12V
direct current to terminal

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 P0216 Confirmation Procedure
WITH CONSULT-II
1) Turn ignition switch to “ON” position.
2) Select “DATA MONITOR” mode with CONSULT-II.
3) Wait at least 2 seconds.
WITHOUT CONSULT-II
1) Turn ignition switch to “ON” position.
2) Wait at least 2 seconds.
3) Turn ignition switch to “LOCK” position, wait at least 5 seconds
and then turn to “ON” position.
4) Perform “Diagnostic Test Mode II” (Self-diagnostic results).
