2004 NISSAN TERRANO engine

qA
CHECK INJECTION TIMING.
1. Set No. 1 piston at TDC on its com-pression stroke.
2. Remove injection tubes and air bleeder on the back of injection pump.
3. Set dial gauge so its indicator points to somewhere between 1.0 and 2.0 mm
(0.039 and 0.079 in) on the scale.
4. Turn crankshaft two turns clockwise and check that dial gauge indicates the
same value again.
5. Turn crankshaft counterclockwise about 100 degrees, then turn crankshaft
clockwise slowly, and set dial gauge
indicator to 0 mm at the position it
stops.
6. Turn crankshaft clockwise and set it at TDC using the mark on the crankshaft
pulley.
7. Read plunger lift. Plunger lift:0.36   0.02 mm (0.0142   0.0008
in) at TDC
I When repeating the checking, start
with step 5.

Bleed air from fuel system.
After this inspection,
unnecessary diagnostic
trouble code No. might be

Erase the stored memory
in ECM.
Refer to ªHOW TO ERASE
DTCº (EC-344).

INSPECTION END
Adjusting
1. If plunger lift is not within the specified value, adjust by turning injection pump.
I If indication is smaller than the
specified value, turn pump body
away from engine.
I If indication is larger than the speci-
fied value, turn pump body towards
engine.
2. Tighten injection pump securing bolts and nuts.
Nut:
: 20-25N ×m
(2.0 - 2.5 kg-m, 14 - 18 ft-lb)
Bolt:
: 32-42N ×m
(3.3 - 4.3 kg-m, 24 - 31 ft-lb)
3. Remove dial gauge and install air bleeder with new washer.
4. Install injection tubes. Flare nut:
: 20-25N ×m
(2.0 - 2.5 kg-m, 14 - 18 ft-lb)
5. Bleed air from fuel system.

ECM INSPECTION TABLE
Remarks: Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
