Nissan Primera P11. Manual - part 83

Basic Inspection

Precaution:
Perform Basic Inspection without electrical or mechanical
loads applied;

●

Headlamp switch is off,

●

Air Conditioner switch is off,

●

Rear defogger switch is off,

●

Steering wheel is in the straight-ahead position, etc.

BEFORE STARTING
1. Check service records for any

recent repairs that may indicate a
related problem, or the current need
for scheduled maintenance.

2. Open engine hood and check the

following:

●

Harness connectors for faulty con-
nections

●

Vacuum hoses for splits, kinks, or
faulty connections

●

Wiring for faulty connections,
pinches, or cuts

3. Using priming pump, bleed air from

fuel system. Refer to “Fuel Filter
Check” in MA section.

CONNECT CONSULT-II TO THE
VEHICLE.
Connect “CONSULT-II” to the data link
connector for CONSULT-II and select
“ENGINE” from the menu. Refer to EC-
CD-27.

DOES ENGINE START?

Yes

Turn ignition switch to
the “LOCK” position, wait
5 seconds and then start
engine. If engine fails to
start, check malfunction
item.

Run engine for 10 minutes.

CHECK IDLE SPEED.

Read engine idle speed in
“DATA MONITOR” mode with
CONSULT-II.

825 rpm ± 25 (in N position)

--------------------------------------------------------------------------------------------------------------------------------- OR ---------------------------------------------------------------------------------------------------------------------------------

Check idle speed using tachom-
eter tester.

825 rpm ± 25 (in N position)

CHECK INJECTION TIMING.
1. Set No. 1 piston at TDC on its com-

pression stroke.
TDC: Without painted mark

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 2 turns clockwise

and check that dial gauge indicates
the same value again.

5. Turn crankshaft counterclockwise

about 100 degrees, then turn crank-
shaft slowly clockwise, and set dial
gauge indicator to 0 mm at the posi-
tion it stops.

6. Turn crankshaft clockwise and set it

at plunger lift timing mark using the
mark on the crankshaft pulley.
plunger lift timing mark: Yellow
painted mark

7. Read plunger lift.

Plunger lift:

0.89 ± 0.08 mm (0.0350 ± 0.0031
in) at plunger lift timing mark

●

When repeating the checking,
start with step 5.

Bleed air from fuel sys-
tem.
After this inspection,
unnecessary diagnostic
trouble code No. might
be displayed.
Erase the stored
memory in ECM.
Refer to “ON BOARD
DIAGNOSTIC SYSTEM
DESCRIPTION”.

INSPECTION END

Adjusting
1. If plunger lift is not within the speci-

fied value, adjust by turning injec-
tion pump.

●

If indication is smaller than the
specified value, turn pump body
away from engine.

●

If indication is larger than the
specified value, turn pump body
towards engine.

2. Tighten injection pump securing

bolts and nuts.

Nut:

: 20 - 25 N·m

(2.0 - 2.6 kg-m, 15 - 18 ft-lb)

Bolt:

: 25 - 35 N·m

(2.6 - 3.6 kg-m, 18 - 26 ft-lb)

3. Remove dial gauge and install air

bleeder with new washer.

4. Install injection tubes.

Flare nut:

: 14 - 20 N·m

(1.4 - 2.0 kg-m, 10 - 15 ft-lb)

5. Bleed air from fuel system.
Refer to “Water Draining, Fuel Filter
Check and Replacement” of
“ENGINE MAINTENANCE” in MA
section.

ENGINE RELATED ITEMS

Detected items

(Screen terms for CONSULT-II,
“SELF-DIAG RESULTS” mode)

Malfunction is detected when ...

Mass air flow sensor circuit
(MASS AIR FLOW SEN)

●

An excessively high or low voltage from the sensor is detected by the ECM.

Engine coolant temperature
sensor circuit
(COOLANT TEMP SEN)

●

An excessively high or low voltage from the sensor is detected by the ECM.

Vehicle speed sensor circuit or
ABS actuator and electric unit
(control unit) circuit
(VEHICLE SPEED SEN)

●

The almost 0 km/h (0 mph) signal from the sensor is detected by the ECM even when
vehicle is being driven.

Control sleeve position sensor
circuit
(CONT SLEEV POS SEN)

●

An excessively high or low voltage from the sensor is detected by the ECM.

●

An incorrect voltage signal from the sensor is detected by the ECM during engine run-
ning.

Fuel injection feedback 2
(F/INJ F/B 2)

●

The fuel injection feedback system (consists of the ECM, electric governor and control
sleeve position sensor) does not operate properly.

Fuel injection timing feedback
(F/INJ TIMG F/B)

●

The fuel injection timing feedback system (consists of the ECM, fuel injection timing con-
trol valve and needle lift sensor) does not operate properly.

Abbreviations for Quick Reference of “DIAGNOSTIC TROUBLE CONFIRMATION PROCEDURE”
IGN: ON

: Turning the ignition switch ON is required for checking the function of the sensor, switch, solenoid and circuit.

RUNNING : Running engine is required for checking the function of the sensor, switch, solenoid and circuit.
LIFTING

: Lifting up the vehicle, running engine and spinning wheels are required.

DRIVING : Driving the vehicle in the specified pattern is required.

Abbreviations for Quick Reference of “OVERALL FUNCTION CHECK”
IGN: ON

: Turning the ignition switch ON is required for the ECM to detect a malfunction (if one exists).

RUNNING : Running engine is required for the ECM to detect a malfunction (if one exists).
LIFTING

: Lifting up the vehicle, running engine and spinning wheels are required for the ECM to detect a malfunction (if one

exists).

DRIVING : Driving the vehicle in the specified pattern is required for the ECM to detect a malfunction (if one exists).

*1:

●

This is Quick Reference of “DIAGNOSTIC TROUBLE CONFIRMATION PROCEDURE”.
Details are described in each TROUBLE DIAGNOSIS.

*2:

●

The “OVERALL FUNCTION CHECK” is a simplified and effective way to inspect a component or circuit.
In some cases, the “OVERALL FUNCTION CHECK” is used rather than a “DIAGNOSTIC TROUBLE CONFIRMATION PRO-
CEDURE”.
When no DIAGNOSTIC TROUBLE CONFIRMATION PROCEDURE is available, the “NG” result of the OVERALL FUNCTION
CHECK can be considered to mean the same as a malfunction item detection.

●

During an “NG” OVERALL FUNCTION CHECK, the malfunction item might not be confirmed.

●

This is Quick Reference of “OVERALL FUNCTION CHECK”.
Details are described in each TROUBLE DIAGNOSIS.
