Nissan Terrano model r20 series 2004. Instruction — part 170
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
q
9
and
q
8
.
If NG, replace TVC and shut-off (fuel cut solenoid valve).

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).

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 “ON” position and select “DATA MONI-
TOR” 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 “LOCK” position, wait at least 5 seconds
and then turn to “ON” position.
3) Perform “Diagnostic Test Mode II” (Self-diagnostic results).
NOTE:
If a malfunction occurs intermittently, conduct suitable driving
pattern for 10 minutes. This makes it possible to determine
DTC.
