Description
SYSTEM DESCRIPTION
The ECM and the electronic control fuel injection pump control unit
(abbreviated as the injection pump control unit) perform the real
time communication (signal exchange).
The ECM transmits the signals of the target fuel injection amount,
target fuel injection timing, and engine speed, etc., and receives the
signals of the pump speed and fuel temperature, etc. from the
injection pump control unit.
By those signals, the injection pump controls the optimum fuel
injection amount and injection timing of the spill valve and timing
control valve.
Injection pump control unit has an on board diagnostic system,
which detects malfunctions related to sensors or actuators built-into
electronic control fuel injection pump. These malfunction informa-
tion are transferred through the line (circuit) from injection pump
control unit to ECM.
FUEL INJECTION AMOUNT CONTROL
In accordance with the target fuel injection amount signal from the
ECM, the injection amount is controlled by controlling the spill valve
in the injection pump and by changing the needle opening time.
FUEL INJECTION TIMING CONTROL
Based on the target fuel injection timing signal from the ECM, the
injection timing is controlled in accordance with the timer spring by
performing the duty control of the timing control valve in the injec-
tion pump and by adjusting the pressure of the timer piston high
pressure chamber.
FUEL TEMPERATURE SENSOR
The sensor detects the fuel temperature in the injection pump and
calibrates the injection amount change by the fuel temperature.
CAM RING POSITION SENSOR
The sensor detects the passing of the protrusion on the sensor
wheel in the injection pump by the semiconductor magnetic resis-
tance element sensor. The cam ring position sensor synchronizes
with the cam ring, and detects the actual advance amount. The
injection pump control unit measures the injection pump revolution
by the signal of the cam ring position sensor.

(2) Obtain intersection point of lines in accordance with the graph.
Front: 1.4 mm
Rear: 2.0 mm
(3) Choose shims which are nearest to the values found in the
graph:
Front: 1.6 mm
Rear: 2.0 mm
(4) If shim thicknesses as calculated appear not to be available,
combinations of different shims should be used to meet the
desired total thickness of the shims.

General maintenance includes those items which should be checked during normal day-to-day operation of
the vehicle. They are essential if the vehicle is to continue functioning correctly. Owners can perform the
checks and inspections themselves, or they can be carried out by a NISSAN dealer.
Item Reference pages
OUTSIDE THE VEHICLE
The maintenance items listed here should be checked periodically, unless otherwise specified.
TiresCheck the pressure with a gauge weekly when at a service station, including the spare,
and adjust to the specified pressure if necessary. Check carefully for damage, cuts or excessive
wear.Ð
Windshield wiper bladesCheck for cracks or wear if not functioning correctly. Ð
Doors and engine hoodCheck that all doors, the engine hood, the trunk lid and back door
function correctly. Also ensure that all latches lock securely. Lubricate if necessary. Make sure
that the secondary latch prevents the hood from opening when the primary latch is released.
When driving in areas using road salt or other corrosive materials, check for lubrication more
often.MA-45
Tire rotationTires should be rotated every 5,000 km (3,000 miles). MA-43
INSIDE THE VEHICLE
The maintenance items listed here should be checked on a regular basis, such as when per-
forming periodic maintenance, cleaning the vehicle etc.
LightsMake sure that the headlights, stop lights, tail lights, turn signal lights, and other lights
are all operating correctly and installed securely. Also check headlight aim.Ð
Warning lights and buzzers/chimesMake sure that all warning lights and buzzers/chimes are
functioning correctly.Ð
Steering wheelCheck that it has the specified play. Check for changes in the steering
operation, such as excessive free play, hard steering or strange noises.
Free play: Less than 35 mm (1.38 in)Ð
Seat beltsCheck that all parts of the seat belt system (e.g. buckles, anchors, adjusters and
retractors) operate properly and smoothly, and are installed securely. Check the belt webbing for
cuts, fraying, wear of damage.MA-46
UNDER THE HOOD AND VEHICLE
The maintenance items listed here should be checked periodically e.g. each time you check the
engine oil or refuel.
Windshield washer fluidCheck that there is adequate fluid in the tank.
Engine coolant levelCheck the coolant level when the engine is cold. MA-22
Engine oil levelCheck the level after parking the vehicle (on level ground) and turning off the
engine.MA-21
Brake and clutch fluid levelMake sure that the brake fluid level is between the ªMAXº and
ªMINº lines on the reservoir.MA-36/MA-40
BatteryCheck the fluid level in each cell. It should be between the ªMAXº and ªMINº lines. Ð
