WHEN IDLE SPEED NEEDS TO BE REDUCED.

APPLIED VEHICLES:

All 2002 - 2005 models

IF YOU CONFIRM

The idle in Park or Neutral is more than 25 rpm above specification (with the engine warm) and/or DTC P0507 (ISC SYSTEM) is stored

NOTE:

^ This incident may be the result of recent cleaning or replacement of the throttle body. The vehicle "in-use" learned idle (IAVL) may be

higher after throttle body deposits are reduced (by cleaning or replacement).

^ If DTCs other than P0507 are stored you must correct the cause for those DTCs first. After correcting other DTCs if you still have a P0507

188

and/or an idle condition above specification continue with this bulletin.

ACTIONS

To reduce idle RPM perform the following in this order until IAVL successfully completes:

1. Check engine for vacuum leaks.

2. Perform IAVL procedure.

3. For 2002 and 2003 models: Check for newer ECM reprogramming data. If it's available perform reprogramming then try IAVL again. 2004

and 2005 models: Skip this step.

4. Reduce idle speed manually:

a. Disconnect injectors one at a time until IAVL completes (see step 4 of the Service Procedure for details)

b. Reconnect the injectors clear DTCs and perform final IAVL.

IMPORTANT:

The purpose of "ACTIONS" (above) is to give you a quick idea of the work you will be performing. You MUST closely follow the entire

Service Procedure as it contains information that is essential to successfully completing this repair.

CLAIMS INFORMATION

Submit a Primary Failed Part (PP) line claim using the claims coding shown.

SERVICE PROCEDURE

NOTE:

After completing repairs in this procedure make sure any stored DTCs are erased.

1. Make sure there are no engine vacuum leaks. Repair any vacuum leaks that are found. Make sure to check:

^ Hoses

^ Intake Manifold

^ Ducting between Intake Manifold and MAFS

189

2. Perform Idle Air Volume Learning (IAVL) procedure as follows.

NOTE:

The IAVL procedure will normally complete within 2 minutes after Procedure Start.

A. Make sure all DTCs are cleared (erased).

B. Use CONSULT-II to confirm / perform the Pre-Conditions shown.

NOTE:

The IAVL procedure will self-cancel if any of the following Pre-Conditions are not met and maintained for as long as the procedure is

running.

C. Turn ignition switch "OFF" and wait at least 10 seconds.

D. Start the engine and let it idle for at least 30 seconds.

E. Using CONSULT-II select [WORK SUPPORT] > [IDLE AIR VOL LEARN].

F. Touch STAR and wait 20 seconds to 2 minutes.

^ If CMPLT is displayed on CONSULT-II screen; go to G next step.

^ If INCMP is displayed within 2 minutes or test is not finished within 2 minutes Idle Air Volume Learning was not carried out

successfully; go to step H.

G. Rev up the engine two or three times then let the engine idle. Verify the idle speed is within specifications. Refer to the EC section of

the appropriate Service Manual for specifications. If OK procedure ends here. If not go to step H.

H. If IAVL did not complete and you're sure you:

^ Set all of the preconditions exactly as shown in the chart above, and

^ Performed steps A through F exactly as shown above.

Go to step 3.

NOTE:

Step 3 below covers 2002 and 2003 vehicles only. For 2004 and 2005 vehicles; skip to step 4.

^ For 2004 and 2005 model years ECM reprogramming will not clear the vehicle in-use learned IAVL. Reprogramming won't reduce

the Idle speed.

3. For 2002 - 2003 vehicles; you may be able to reduce the engine idle speed by performing ECM reprogramming. Reprogramming may clear

the vehicle in-use learned IAVL.

A. With the ignition ON and CONSULT-II connected to the vehicle print your current ECM Part Number (P/N) as follows:

[START (Nissan)] >> [ENGINE] >> [ECM PART NUMBER] >> [COPY]

190

to D.

^ If your current ECM P/N is not listed in the Details panel new ECM data is not available for your vehicle go to step 4.

D. After following all steps of the reprogramming procedure perform IAVL again

^ If the IAVL procedure now completes the incident is fixed and you're done.

^ If the IAVL procedure still does not complete go to step 4.

4. Reduce the engine idle speed manually and perform IAVL as follows:

A. With the engine running disconnect 1 fuel injector (engine rpm should drop MIL may come ON).

CAUTION:

Do Not disconnect the ignition (coils or spark plugs) for this step. Disconnecting the ignition while the engine is running may cause

damage to the catalysts.

B. With the injector(s) disconnected and the engine running perform IAVL (step 2). NOTE: Make sure all DTCs are cleared

^ If "CMPLT" is displayed on CONSULT-II screen within 2 minutes; go to step 5.

^ If INCMP is displayed or test is not finished within 2 minutes:

191

a. Disconnect another injector.

b. Repeat step B above

NOTE:

^ For 4 cylinder engines up to 2 injectors can be disconnected one at a time.

^ For 6 and 8 cylinder engines up to 3 injectors can be disconnected one at a time. It is best that 3 disconnected injectors

(particularly on V6 engines) not all be on the same engine bank.

5. Final IAVL procedure.

A. Make sure all injectors are connected.

ECM REPROGRAM INTERRUPTION RECOVERY PROCEDURE

SERVICE INFORMATION

A complete step-by-step General Procedure for CONSULT-III (C-III) ECM Reprogram Interruption Recovery is now available in this bulletin as a

attachment.

While performing ECM (Engine Control Module) reprogramming, the reprogramming may stop (become interrupted) before it is 100% complete.

One of two messages may appear:

^ The VI probe is disconnected on USB, please check the connection of the probe.

^ Reprogramming fail, "Error code 0".

426

In many cases, reprogramming recovery is possible and the ECM may not need to be replaced if the complete ECM part number has been registered

into the ECM before reprogramming stopped.

NOTE:

ECM is referred to as ECU in C-III.

The ECM Reprogram Interruption Recovery General Procedure applies to Technical Service Bulletins that include ECM reprogramming published

in April 2010 and later.

IMPORTANT: BEFORE STARTING REPROGRAMMING

^ Connect a battery charger to the vehicle battery.

^ Be sure to turn OFF all vehicle electrical loads.

^ For ECM reprogramming, the C-III MUST be connected to the VI using the USB cable.

^ Be sure to connect the AC Adapter.

REMOVAL PROCEDURE FOR SEIZED EXHAUST SENSOR

APPLIED VEHICLES:

All Infiniti vehicles

SERVICE INFORMATION

If an exhaust sensor is seized in the exhaust manifold/catalyst/front tube perform the procedure described in this bulletin to remove the sensor and

prevent unnecessary replacement of the exhaust manifold/catalyst/front tube.

In most cases this procedure is successful. This is because the threads of the exhaust sensors are made of a softer material than the part they thread

into on the exhaust manifold/catalyst/front tube.

NOTE:

The replacement of exhaust manifolds/catalysts/front tubes for stripped exhaust sensor threads may not be considered a warrantable expense.

This procedure can be performed by two methods:

Method # 1. If the Sensor Can Be Easily Accessed

^ The procedure can be performed on the vehicle.

^ The exhaust manifold/catalyst/front tube will not have to be removed.

Method # 2. If the Sensor Cannot Be Easily Accessed

^ The exhaust manifold/catalyst/front tube must be removed from the vehicle.

^ The procedure will be performed with the part clamped in a vice.

Method # 2 is described in this bulletin. Method # 1 is the same as Method # 2 except that it is performed on the vehicle.

SERVICE PROCEDURE

Rust Penetrant

Recommended rust penetrants to be used in this procedure:

NOTES:

^ Rust penetrant is considered a shop supply.

^ Nissan Rust Penetrant can be ordered through the Nissan Direct Ship Chemical Care Product Program: Website order via link on dealer

portal.

^ WD-40 is available from various local sources.

Removal Tool

^ When removing a seized exhaust sensor with a specialty socket (which contains a slit to accommodate the wiring harness) it may spread open

and strip the sensor.

^ Before this occurs it is recommended to cut the wiring harness from the sensor and use a box end wrench or 6-point deep well socket.

1. Clamp the exhaust manifold/catalyst/front tube in a vice.

410

2. Spray the sensor with the rust penetrant for 2 to 3 seconds.

^ It is important that the spray is directed at the base of the sensor to ensure it penetrates into the threads.

3. Loosen the sensor approximately 10 degrees.

4. Spray with rust penetrant again for 2 to 3 seconds.

5. Tighten the sensor 10 degrees then loosen the sensor 10 degrees.

^ Repeat this motion several times until the sensor begins to turn more easily.

6. Continue the tightening/loosening motion while gradually unscrewing the sensor. Stop when the sensor will not unscrew any further.

7. Spray with rust penetrant again for 2 to 3 seconds.

411

8. Repeat steps 6 and 7 until the sensor is removed.

9. Use compressed air to remove any metal debris from inside the boss threads.

CAUTION:

DO NOT perform this step if the procedure is being done on the vehicle (Method # 1). Doing so may cause metal debris to enter the engine

cylinders.

10. If metal debris remains trapped in the boss threads use a spiral nylon brush to remove it.

11. Spray the boss threads with rust penetrant for 2 to 3 seconds.

12. Run a thread chaser through the boss to clean the threads.

^Use Kent Moore part number J-43897-18 or J43897-12.

13. Use compressed air to remove any remaining debris.

CAUTION:

DO NOT perform this step if the procedure is being done on the vehicle (Method # 1). Doing so may cause metal debris to enter the engine

cylinders.

14. If metal debris remains trapped in the boss threads use a spiral nylon brush to remove it.

15. Tilt the manifold/catalyst/front tube so that the metal debris falls out of the part.

16. Apply compressed air through the boss to blow out any remaining debris.

412

CAUTION:

DO NOT perform this step if the procedure is being done on the vehicle (Method # 1 ). Doing so may cause metal debris to enter the

engine cylinders.

17. Install the new sensor as described in the applicable Electronic Service Manual (ESM).
