Nissan Terrano model r20 series 2004. Instruction — part 171
Diagnostic Procedure
INSPECTION START
CHECK FOR AIR IN FUEL FILTER.
1. Move priming pump up and down to
purge air from fuel filter.
2. Perform “DIAGNOSTIC TROUBLE
CODE CONFIRMATION PROCE-
DURE”.
CHECK POWER SUPPLY.
1. Turn ignition switch to “LOCK” position.
2. Disconnect TVC and shut-off (injection
timing control valve) harness connec-
tor.
3. Turn ignition switch to “ON” position.
4. Check voltage between TVC and shut-
off (injection timing control valve) con-
nector terminal
q
9
and engine ground
with CONSULT-II or tester.
Voltage: Battery voltage

F66
I
20A fuse
I
ECM relay
I
Harness for open or
short-circuit between
TVC and shut-off (injec-
tion timing control valve)
harness connector and
fuse box.
If NG, replace 20A fuse or
ECM relay, harness or con-
nectors.
CHECK OUTPUT SIGNAL CIRCUIT.
1. Turn ignition switch to “LOCK” position.
2. Disconnect ECM harness connector.
3. Check harness continuity between TVC
and shut-off (injection timing control
valve) connector terminal
q
8
and ECM
terminals
202
. Refer to wiring dia-
gram.
Continuity should exist.
If OK, check harness for short-circuit.
OK
E
NG
Check the following:
I
Harness for open or
short-circuit between
TVC and shut-off (injec-
tion timing control valve)
and ECM
If NG, repair harness or
connectors.
CHECK GROUND CIRCUIT.
1. Disconnect ECM harness connector.
2. Check harness continuity between
ECM connector terminal
349
and TVC
and shut-off (injection timing control
valve) connector terminal
q
10
. Refer to
wiring diagram.
Continuity should exist.
If OK, check harness of short-circuit.

Replace injection timing
control 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.
INSPECTION END
Component Inspection
[TVC AND SHUT-OFF (INJECTION TIMING CONTROL
VALVE)]
1. Disconnect TVC and shut-off (injection timing control valve)
harness connector.
2. Check resistance between terminals
q
9
and
q
10
.
Resistance: Approximately 15
Ω
[at 25°C (77°F)]
If NG, replace injection timing control valve.

Diagnostic Procedure (Cont’d)
EC-407
Component Description
CRANKSHAFT POSITION SENSOR (TDC)
The crankshaft position sensor (TDC) monitors engine speed by
means of signals from the sensing plate (with four protrusions)
installed to the clutch housing. The datum signal output is detected
at ATDC 30° and sent to the ECM. The sensor signal is used for
fuel injection control and fuel injection timing control.
On Board Diagnosis Logic
DTC
Malfunction is detected when .
Check Items
(Possible cause)
P0335
0407
I
An improper signal from the sensor is detected by
ECM during engine running and cranking.
I
Harness or connectors
(The sensor circuit is open)
I
Crankshaft position sensor (TDC)
DTC Confirmation Procedure
I
If DTC P1240 is displayed same time, perform trouble diag-
nosis for DTC P1240 first.
I
Before performing the following procedure, confirm that
battery voltage is more than 9V.
WITH CONSULT-II
1) Turn ignition switch to “ON” position and select “DATA MONI-
TOR” mode with CONSULT-II.
2) Start engine and run it for at least 3 seconds at above 1,200
rpm.
WITHOUT CONSULT-II
1) Start engine and run it for at least 3 seconds at above 1,200
rpm.
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).
