2002 NISSAN TERRANO fuel pressure

5. Bleed the air from the rear brake piping.
6. To adjust the LSV correctly, proceed as follows:
a. With unladen vehicle (12 liters of fuel, radiator coolant and
engine oil are full). Spare tire, hand tools and mats in desig-
nated positions. Check the length of LSV spring ªLº.
b. If the spring length is different from that specified, move the
regulation lever (2) until the specified value is obtained. Move
the LSV lever (1) until it contacts the stopper bolt and recheck
the spring length.
Sensor spring length ªLº
Hardtop: 201 mm (7.913 in)
Wagon: 197.5 mm (7.776 in)
NOTE: Do not disturb stopper bolt.
c. Start the engine and run it at idling speed.
d. Slowly depress the brake pedal until an input pressure of 4,805
kPa (48.1 bar, 49 kg/cm
2, 697 psi) is obtained (at the front axle
pressure gauge) and an output pressure of 1,736 - 2,501 kPa
(18 - 26 bar, 17.7 - 25.5 kg/cm
2, 252 - 363 psi) is obtained (at
the rear axle pressure gauge).
If the output pressure at the rear axle pressure gauge is not within
the specified values, adjust LSV spring length as described under
b) until the output pressure measured is within the specified range.
Unit: kPa (bar, kg/cm2, psi)
Front axle* 4,805 (48.1, 49.0, 697)
Rear axle* 1,736 - 2,501 (18 - 26, 17.7 - 25.5, 252 - 363)
* Load conditions as indicated under 6.a, driver seat occupied.

Inspection for spill tube airtightness
Before the rocker cover is installed, perform the inspection as fol-
lows.
1. Connect the handy vacuum pump to the spill hose.
2. Check that the airtightness is maintained after the negative
pressure shown below is applied.
Standard:
þ53.3 to þ66.7 kPa (þ533 to þ667 mbar, þ400 to
þ500 mmHg, þ15.75 to þ19.69 inHg)
Air bleeding of fuel piping
After the repair, bleed air in the piping by pumping the priming
pump up and down until it becomes heavy.
Injection pressure test
1. Install injection nozzle assembly 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
19,026 kPa (190.3 bar, 194 kg/cm
2, 2,759 psi)
New
19,516 - 20,497 kPa (195.2 - 205.0 bar, 199 - 209
kg/cm
2, 2,830 - 2,972 psi)
Limit
16,182 kPa (161.8 bar, 165 kg/cm
2, 2,346 psi)
IThe injection nozzle assembly has a 2-stage pressure injection
function. However, the judgement should be made at the first
stage of the valve opening pressure.
