1998 NISSAN PICK-UP warning

EVAP Canister Purge Control Solenoid Valve
COMPONENT DESCRIPTION
EVAP canister purge control solenoid valve
The EVAP canister purge control solenoid valve responds to
signals from the ECM. When the ECM sends an OFF signal, the
vacuum signal (from the throttle body to the EVAP canister purge
control valve) passes through the EVAP canister purge control
solenoid valve. The signal then reaches the EVAP canister purge
control valve.
When the ECM sends an ON (ground) signal, the vacuum sig-
nal is cut.

Assembly
Assemble in the reverse order of disassembly.
Inlet connector to nozzle holder:
:29-49Nzm (3.0 - 5.0 kg-m, 22 - 36 ft-lb)
Test and Adjustment
WARNING:
When using nozzle tester, be careful not to allow diesel fuel
sprayed from nozzle to contact your hand or body, and
make sure your eyes are properly protected with goggles.
INJECTION PRESSURE TEST
1. Install nozzle to injection nozzle tester and bleed air from
flare nut.
2. Pump the tester handle slowly (one time per second) and
watch the pressure gauge.
3. Read the pressure gauge when the injection pressure just
starts dropping.
Initial injection pressure:
Used 9,807 - 10,297 kPa
(98.1 - 103.0 bar, 100 - 105 kg/cm
2,
1,422 - 1,493 psi)
New 10,297 - 11,278 kPa
(103.0 - 112.8 bar, 105 - 115 kg/cm
2,
1,493 - 1,635 psi)
Always check initial injection pressure using a new nozzle.

Bleeding Fuel Filter
1. Move the priming pump up and down to bleed air from the
fuel filter.
2. When air is completely bled from the fuel pump, priming
pump operation becomes noticeably heavy. Stop pump
operation.
Checking Priming Pump
Before checking priming pump, make sure that fuel filter is
filled with fuel.
1. Disconnect fuel return hose.
Place a suitable container beneath hose end.
2. Pump priming pump and check that the fuel overflows from
the hose end. If not, replace priming pump.
Checking Fuel Filter Switch
1. Remove the connector from filter and fuel filter switch.
2. Turn the key switch ``ON''. Lift the float to ensure that the
warning lamp turns on.
Fuel filter switch tightening torque:
: 3.9 - 5.9 Nzm (0.4 - 0.6 kg-m, 35 - 52 in-lb)
Discard the old O-ring and replace it with a new one.

FUEL SYSTEM CHECKTD
EC-192

When installing, use a new O-ring.
WARNING:
Do not touch the cooled fuel temperature switch with your
bare hand.
Oil pressure switch
1. Run engine at about 1,000 rpm.
2. Check continuity for oil pressure switch.
3. If oil pressure switch has malfunction, replace it.
Fuel heater relay
1. Check fuel heater relay operation.
2. If fuel heater relay does not operate, replace it.

Supplemental Restraint System (SRS) ``AIR
BAG'' (4WD models)
The Supplemental Restraint System ``AIR BAG'', used along with a seat belt, helps to reduce the risk or
severity of injury to the driver in a frontal collision. The Supplemental Restraint System consists of an air
bag module (located in the center of the steering wheel), a diagnosis sensor unit, warning lamp, wiring har-
ness and spiral cable. Information necessary to service the system safely is included in theRS sectionof
this Service Manual.
WARNING:
lTo avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag inflation, all maintenance must be per-
formed by an authorized NISSAN dealer.
lImproper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system.
lDo not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses are covered with yellow insulation either just before the
harness connectors or for the complete harness, for easy identification.

formed by an authorized NISSAN dealer.
lImproper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system.
lDo not use electrical test equipment on any circuit related to the SRS.
