SENTRA; INTERMITTENT LOW ENGINE RPM AT IDLE
OR STOPS RUNNING COMING TO A STOP
This bulletin has been amended to APPLIED VEHICLES. ECM part numbers
have been added to Table A. Discard all previous versions of this bulletin.

APPLIED VEHICLE: 2013 and 2014 Sentra (B17)

IF YOU CONFIRM:
The engine RPM intermittently drops very low while stopped (idling) or the engine stops
running while coming to a stop.
NOTE: These symptoms can occur under the following conditions:
•

Low engine RPM at idle while the A/C is off and without any electrical load from the
alternator

•

The engine speed (RPM) becomes low while coming to a stop with the A/C on

•

The engine stops running when coming to a stop

ACTION:
1. Refer to the Repair Overview on page 2 to determine if this bulletin applies.
NOTE: On certain specific 2013 Sentra vehicles campaign ID P3212 / NTB13-022 may
apply. Make sure to use the Repair Overview to determine if the campaign bulletin or
this bulletin applies, or neither apply.

IMPORTANT: The purpose of ACTION (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.
Nissan Bulletins are intended for use by qualified technicians, not 'do-it-yourselfers'. Qualified technicians are
properly trained individuals who have the equipment, tools, safety instruction, and know-how to do a job
properly and safely. NOTE: If you believe that a described condition may apply to a particular vehicle, DO
NOT assume that it does. See your Nissan dealer to determine if this applies to your vehicle.

SERVICE PROCEDURE
NOTE:
•

Most instructions for reprogramming with CONSULT-III plus (C-III plus) are
displayed on the CONSULT PC screen.

•

If you are not familiar with the reprogramming procedure, click here. This will link
you to the "CONSULT- III plus (C-III plus) Reprogramming" general procedure.

•

Take the vehicle for a 10 minute drive in order to meet the following Idle Air Volume
Learn (IAVL) conditions:

¾ Engine coolant temperature: 70 -100°C
(158 - 212°F)
¾ Battery voltage: More than 12.9V (At idle)
¾ Transmission: Warmed up
Figure A
•

After reprogramming is complete, you will be required to perform Throttle Valve
Closed Position, Idle Air Volume Learn, Accelerator Closed Position, and DTC
erase.

CAUTION:
•

Connect the GR8 to the vehicle 12 volt battery and set to ECM power supply mode.
If the vehicle battery voltage drops below 12.0V or rises above 13.5V during reprogramming,
the ECM may be damaged.

•

Be sure to turn OFF all vehicle electrical loads.
If a vehicle electrical load remains ON, the ECM may be damaged.

•

Be sure to connect the AC Adapter.
If the CONSULT PC battery voltage drops during reprogramming, the process
will be interrupted and the ECM may be damaged.

•

Turn off all external Bluetooth® devices (e.g., cell phones, printers, etc.) within
range of the CONSULT PC and the VI. If Bluetooth® signal waves are within
range of the CONSULT PC during reprogramming, reprogramming may be
interrupted and the ECM may be damaged.

If there is a match, this bulletin applies. Continue with the reprogramming
procedure.

•

If there is not a match, this bulletin does not apply:
a. For 2013 Sentra vehicles only: Check Service COMM; campaign ID P3212 /

7. Follow the on-screen instructions to navigate C-III plus and reprogram the ECM.

NOTE:
•

In some cases, more than one new P/N for reprogramming is available.
¾ In this case, the screen in Figure 3 displays.
¾ Select and use the reprogramming option that does not have the message
“Caution! Use ONLY with NTBXX-XXX”.

•

If you get this screen and it is blank (no reprogramming listed), it means there is no
reprogramming available for this vehicle. Close C-III plus and refer back to ASIST for
further diagnosis.
