2013 – 2015 SENTRA; MIL ON WITH DTC P0101
This bulletin has been amended throughout. Discard all previous versions of this bulletin.

APPLIED VEHICLE:

2013 – 2015 Sentra (B17)

IF YOU CONFIRM
The MIL is ON with DTC P0101 (MAF SEN/CIRCUIT-B1) stored.
and
There are no drivability issues.

ACTION
1. For 2013 and 2014 models only:


Inspect the color of the PCV valve, replace if the color is orange
(see Figure 1a on page 2).

2. For 2013-2015 models: Clean the throttle valve and chamber of the electronic throttle
control actuator.
3. For 2013-2015 models: Reprogram the ECM.


Refer to step 6 in the ECM Reprogramming/Confirmation section of the SERVICE
PROCEDURE to confirm if reprogramming is needed.

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
Inspect / Replace PCV Valve (2013- 2014 Sentra Only)
1. Open the engine hood and locate the PCV
valve.
2. Inspect the color of the PCV valve.

PCV valve

If the PCV valve is orange, as shown
in Figure 1a:


Replace the PCV valve.



Refer to the Electronic Service Manual
(ESM), section EM-Engine Mechanical,
for replacement information.



Install the new PCV valve listed in
PARTS INFORMATION.
NOTE: The new PCV valve is “black”
color.

Figure 1a

If the PCV valve is black:


DO NOT replace – continue with the SERVICE PROCEDURE.

Electronic Throttle Control Actuator – Clean Throttle Valve and Chamber

ETC

1. Remove the electronic throttle control
actuator (ETC).


Refer to the ESM, section EM-Engine
Mechanical, for ETC removal.

2. On the engine-side of the ETC, clean off
deposits on the chamber and throttle
valve.

Figure 2a

3. Spray “carburetor” cleaner on a clean cloth towel.


Do not use a paper towel.



For warranty repairs, use only Nissan Genuine Low VOC Non-Chlorinated
Carburetor Cleaner.



For non-warranty repairs, Nissan Genuine Low VOC Non-Chlorinated Carburetor
Cleaner is recommended, but an equivalent “carburetor” cleaner may be used.
 See PARTS INFORMATION for further details.

CAUTION: Do not spray directly on the ETC chamber. Damage may occur to the
electronics of the ETC.

4. Clean the throttle valve and chamber with the soaked cloth towel.


Clean off the deposits from the edges and outer ends of the throttle valve (see
Figure 5a).



Clean off the areas of the chamber where the throttle valve meets up to and around
it.
 Hold the valve open to access these areas.
CAUTION:
o Do not use excessive force when opening the throttle valve.
o Be careful not to scratch the throttle valve or chamber areas during cleaning.

unobstructed clearance is seen between
the throttle valve and chamber (see
Figure 6a).

6. Reinstall the ETC.




Refer to the ESM, section EMEngine Mechanical, for ETC
installation.

Figure 6a

Install a new ETC gasket.
 Do not reuse the old ETC gasket.

7. Refer to step 6 in the ECM Reprogramming/Confirmation section of the SERVICE
PROCEDURE to confirm if reprogramming is needed.
NOTE: Throttle Valve Closed Position Learning and Idle Air Volume Learning is
included in the reprogramming procedure.
8. If ECM reprogramming is not needed, refer to the ESM, section EC-Engine Control,
and perform Idle Air Volume Learning (IAVL). This includes:


Accelerator Pedal Position Learning, and



Throttle Valve Closed Position Learning.

ECM Reprogramming/Confirmation
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) ECM Reprogramming" general procedure.



Take the vehicle for a 10 minute drive in order to meet the following Idle Air Volume
Learn (IAVL) conditions:
 Engine coolant temperature: 70 -100°C
(158 - 212°F)
 Battery voltage: More than 12.9V (At idle)
 Transmission: Warmed up


After reprogramming is complete, you will be
required to perform Idle Air Volume Learn.
The above condition are required for Idle Air
Volume Learn to complete.

CAUTION:





Connect the GR8 to the 12V battery and select ECM Power Supply Mode.
If the vehicle battery voltage drops below 12.0V or above 15.5V 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 plus VI. If Bluetooth® signal
waves are within range of the CONSULT PC during reprogramming,
reprogramming may be interrupted and the ECM may be damaged.

1. Connect the CONSULT PC to the vehicle to begin the reprogramming procedure.
2 Start C-III plus.
3. Wait for the plus VI to be recognized.


The serial number will display when the plus VI is recognized.

4. Select Re/programming, Configuration.

Step 3:
plus VI is
recognized

6. When you get to the screen shown in Figure 2, confirm this bulletin applies as follows.

A. Find the ECM Part Number and write it on the repair order.

NOTE: This is the current ECM Part Number (P/N).

6A: Current
ECM P/N

Figure 2

B. Compare the P/N you wrote down to the numbers in the Current ECM Part Number
column in Table A on the next page.


If there is a match, continue with the reprogramming procedure.



If there is not a match, reprogramming is not needed.
