THROTTLE VALVE CLOSED
POSITION LEARNING
DescriptionINFOID:0000000012431356
Throttle Valve Closed Position Learning is a function of ECM to learn the fully closed position of the throttle
valve by monitoring the throttle position sensor out put signal. It must be performed each time harness connec-
tor of electric throttle control actuator or ECM is di sconnected or electric throttle control actuator inside is
cleaned. Refer to EC-129, "
Work Procedure".
Work ProcedureINFOID:0000000012431357
1.START
WITH CONSULT
1. Turn ignition switch ON.
2. Select “CLSD THL POS LEARN” in “WORK SUPPORT” mode.
3. Follow the instructions on the CONSULT display.
4. Turn ignition switch OFF and wait at least 10 seconds. Check that throttle valve moves during the above 10 seconds by confirming the operating sound.
WITHOUT CONSULT
1. Start the engine.
NOTE:
Engine coolant temperature is 25 °C (77° F) or less before engine starts.
2. Warm up the engine. NOTE:
Raise engine coolant temperature until it reaches 65 °C (149 °F) or more.
3. Turn ignition switch OFF and wait at least 10 seconds. Check that throttle valve moves during the above 10 seconds by confirming the operating sound.

IDLE AIR VOLUME LEARNING
IDLE AIR VOLUME LEARNING
DescriptionINFOID:0000000012431358
Idle Air Volume Learning is a function of ECM to learn the idle air volume that keeps each engine idle speed
within the specific range. It must be performed under any of the following conditions:
• Each time electric throttle control actuator or ECM is replaced.
• Idle speed or ignition timing is out of specification.
Refer to
EC-130, "
Work Procedure".
Work ProcedureINFOID:0000000012431359
1.PRECONDITIONING

Learning will be cancelled if any of the follo wing conditions are missed for even a moment.
• Battery voltage: More than 12.9 V (At idle)
• Engine coolant temperature: 70 - 100 °C (158 - 212° F)
• Selector lever: P or N (CVT), Neutral (M/T)
• Electric load switch: OFF

starting engine not to illuminate headlamps.
• Apply parking brake
• Set lighting switch to the 1st position
• Steering wheel: Neutral (Straight-ahead position) position
• Vehicle speed: Stopped
• Transmission: Warmed-up
- CVT models
• With CONSULT: Drive vehicle until “FLUID TEMP SE ” in “DATA MONITOR” mode of “TRANSMISSION” sys-
tem indicates less than 0.9 V.

FUEL PRESSURE RELEASE
1.FUEL PRESSURE RELEASE
With CONSULT
1. Turn ignition switch ON.
2. Perform “FUEL PRESSURE RELEASE” in “WORK SUPPORT” mode with CONSULT.
3. Start engine.
4. After engine stalls, crank it two or three times to release all fuel pressure.
5. Turn ignition switch OFF.
Without CONSULT
1. Remove fuel pump fuse located in IPDM E/R.
2. Start engine.
3. After engine stalls, crank it two or three times to release all fuel pressure.

FUEL PRESSURE CHECK
1.FUEL PRESSURE CHECK
CAUTION:
• Before disconnecting fuel line, release fuel pressure from fuel line to eliminate danger.
• The fuel hose connection method used when taki ng fuel pressure check must not be used for other
purposes.
• Be careful not to scratch or put debris around connection area when servicing, so that the quick
connector maintains seal abil ity with O-rings inside.
• Do not perform fuel pressure check with electrical systems operating (i.e. lights, rear defogger, A/C, etc.) Fuel pressure gauge may indicate false readin gs due to varying engine load and changes in
manifold vacuum.
NOTE:
Prepare pans or saucers under the disconnected fuel line because the fuel may spill out. The fuel pres-
sure cannot be completely released because th is models do not have fuel return system.
1. Release fuel pressure to zero.
2. Prepare fuel hose for fuel pressure check (B) and fuel tube adapter [SST: KV10118400 or KV10120000] (D), then connect
fuel pressure gauge (A).
CAUTION:
• Use suitable fuel hose for fuel pressure check (genuine
NISSAN fuel hose without quick connector).
• To avoid unnecessary force or tension to hose, use mod- erately long fuel hose for fuel pressure check.
• Do not use the fuel hose for checking fuel pressure with damage or cracks on it.
• Use Pressure Gauge to check fuel pressure.
3. Remove fuel hose.
CAUTION:
Do not twist or kink fuel hose because it is plastic hose.
