2002 NISSAN TERRANO sensor

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 ªDIAGNOSTIC TROUBLE
CODE CONFIRMATION PROCE-
DUREº.
CHECK INPUT SIGNAL CIRCUIT.
1. Turn ignition switch to ªLOCKº position.
2. Disconnect ECM harness connector
and needle lift sensor harness connec-
tor.
3. Check harness continuity between
needle lift sensor connector terminalq
1and ECM connector terminal345.
Refer to wiring diagram.
Continuity should exist.
If OK, check harness for short-circuit.
OK
ENG
Check the following:
IHarness for open circuit
between needle lift sen-
sor and ECM
If NG, repair harness or
connectors.
CHECK GROUND CIRCUIT-I.
Check harness continuity between needle
lift sensor connector terminalsq
2and ECM
connector terminals333. Refer to wiring
diagram.
Continuity should exist.
If OK, check harness for short-circuit.
OK
ENG
Check the following:
IHarness for open or
short-circuit between
ECM and needle lift sen-
sor.
If NG, repair harness or
connectors.
CHECK GROUND CIRCUIT-II.
Check resistance between ECM connector
terminal
346and engine ground. Refer to
wiring diagram.
Continuity should exist.
If OK, check harness for short-circuit.
OK
ENG
Check the following:
IHarness for open-circuit
between ECM and
engine ground
If NG, repair harness or
connectors.
CHECK NO. 1 INJECTION NOZZLE FOR
CLOGGING.
Refer to spray pattern test of ªINJECTION
NOZZLEº.
If NG, replace No. 1 injection nozzle.

EAir conditioner ªONº signal
The ECM receives signals sent from the engine coolant tempera-
ture sensor, crankshaft position sensor (TDC), ignition switch etc.
to determine engine speed and operating conditions. Based on
these signals, the ECM controls EGRC-solenoid valve (A and B)
operation and throttle solenoid valve operation.
The EGR control stops when engine coolant temperature is below
45ÉC (113ÉF), at idling, at starting and when the system compo-
nents and engine speed signals are disordered.

Component Description
The EGRC-solenoid valves A and B, control vacuum pressure act-
ing on the EGR valve. The EGR control valve will be fully opened,
half-opened or fully closed, as required.
The throttle control solenoid valve controls vacuum pressure acting
on the throttle control valve. Thus, intake air passages are opened
or closed in relation to exhaust gas and intake air. Utilizing the
relationship between exhaust gas pressure and intake air pressure
control, the amount of EGR (exhaust gas recirculated) is regulated
in three approximate measures Ð large, medium, small.

DTC Confirmation Procedure
WITH CONSULT-II
1) Turn ignition switch and air conditioner switch to ªONº position.
2) Select ªDATA MONITORº mode with CONSULT-II.
3) Wait at least 2 seconds.
WITHOUT CONSULT-II
1) Turn ignition switch and air conditioner switch to ªONº position.
Wait at least 2 seconds.
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).
