Idle Speed and Ignition Timing CheckEBS00NDZ
IDLE SPEED
With CONSULT-II
Check idle speed in “DATA MONITOR” mode with CONSULT-II.
Without CONSULT-II
Check the idle speed by installing the pulse type tachometer clamp on the loop wire or on suitable high-tension
wire which installed between No.1 ignition coil and No.1 spark plug.
NOTE:
For the method of installing the tachometer, EC-448, "
IGNITION TIMING" .
IGNITION TIMING

Accelerator Pedal Released Position LearningEBS00NE1
DESCRIPTION
“Accelerator Pedal Released Position Learning” is an operation to learn the fully released position of the accel-
erator pedal by monitoring the accelerator pedal position sensor output signal. It must be performed each time
harness connector of accelerator pedal position sensor or ECM is disconnected.
OPERATION PROCEDURE
1. Make sure that accelerator pedal is fully released.
2. Turn ignition switch “ON” and wait at least 2 seconds.
3. Turn ignition switch “OFF” wait at least 10 seconds.
4. Turn ignition switch “ON” and wait at least 2 seconds.
5. Turn ignition switch “OFF” wait at least 10 seconds.
Throttle Valve Closed Position LearningEBS00NE0
DESCRIPTION
“Throttle Valve Closed Position Learning” is an operation to learn the fully closed position of the throttle valve
by monitoring the throttle position sensor output signal. It must be performed each time harness connector of
electric throttle control actuator or ECM is disconnected.
OPERATION PROCEDURE
1. Make sure that accelerator pedal is fully released.
2. Turn ignition switch “ON” wait at least 10 seconds.

●Do not twist or kink fuel hose because it is plastic hose.
●Do not remove fuel hose from quick connector.
●Keep the original fuel hose to be free from intrusion of dust or foreign substances with a suitable cover.
4. Install the fuel pressure gauge as shown in the figure.
●Wipe off oil or dirt from hose insertion part using cloth moist-
ened with gasoline.
●Apply proper amount of gasoline between top of the fuel tube
and No.1 spool.
●Insert fuel hose for fuel pressure check until it touches the
No.1 spool on fuel tube.
●Use NISSAN genuine hose clamp (part number: 16439
N4710 or 16439 40U00).
●When reconnecting fuel line, always use new clamps.
●When reconnecting fuel hose, check the original fuel hose for
damage and abnormality.
●Use a torque driver to tighten clamps.
●Install hose clamp to the position within 1 - 2 mm (0.04 - 0.08
in).
●Make sure that clamp screw does not contact adjacent parts.
5. After connecting fuel hose for fuel pressure check, pull the hose
with a force of approximately 98 N (10 kg, 22 lb) to confirm fuel
tube does not come off.
6. Turn ignition switch “ON”, and check for fuel leakage.
7. Start engine and check for fuel leakage.
8. Read the indication of fuel pressure gauge.
●Do not perform fuel pressure check with system operating. Fuel pressure gauge may indicate false
readings.
●During fuel pressure check, confirm for fuel leakage from fuel connection every 3 minutes.
9. If result is unsatisfactory, go to next step.
10. Check the following.
●Fuel hoses and fuel tubes for clogging
●Fuel filter for clogging
●Fuel pump
●Fuel pressure regulator for clogging
If OK, replace fuel pressure regulator.
If NG, repair or replace.Tightening
