This bulletin has been amended. See AMENDMENT HISTORY on the last page.
Discard all previous versions of this bulletin.

APPLIED VEHICLES: 2013-2019 NV200 (M20)
2014-2017 and 2019 Taxi (M20)

IF YOU CONFIRM
The MIL is ON and DTC P0101 (MAF SEN/CIRCUIT-B1) is stored.

ACTION
Refer to the FLOW CHART on page 2.

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 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 the PCV Valve
1. Open the hood and confirm the color of the PCV valve (see Figure A).
 If the PCV valve is orange, go to step 2.
NOTE: Orange PCV valves were installed on 2014-2015 Taxi only.


If the PCV valve is black, skip to step 4.

2. Replace the PCV valve with the one listed in PARTS INFORMATION.
3. 2014-2015 Taxi: Check the ECM part number for possible ECM reprogramming
(see page 4):


If ECM reprogramming applies: Reprogram the ECM, repairs are complete.



If ECM reprogramming does not apply: Skip to step 6.

4. Inspect the PCV valve per the ESM.




PDF and HTML Electronic Service Manuals (ESM): Refer to EC > MR20DE >
PERIODIC MAINTENANCE > POSTITIVE CRANKCASE VENTILATION >
Inspection for PCV valve inspection.
If NG, go to step 5.



If OK, STOP HERE. Refer to ASIST and the ESM for DTC P0101 diagnosis.

5. Replace the PCV valve with the one listed in PARTS INFORMATION.
6. Perform Idle Air Volume Learn (see page 10).
7. Erase the DTC.

Check ECM Part Number / ECM Reprogramming (2014-2015 Taxi ONLY)
IMPORTANT: Before starting, make sure:


ASIST on the CONSULT PC has been synchronized (updated) to the current date.



All CONSULT-III plus (C-III plus) software updates (if any) have been installed.



The CONSULT PC is connected to the Internet (Wi-Fi or cable).

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 IAVL. The above conditions
are required for IAVL to complete.

Figure B

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 and plus VI during
reprogramming, reprogramming may be interrupted and the ECM may be
damaged.

7. Compare the P/N you wrote down to the P/Ns in the CURRENT ECM PART NUMBER
column in Table A.


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



If there is not a match, reprogramming is not needed.
 Perform IAVL and erase the DTC. Repairs are now complete.

In some cases, more than one new P/N for reprogramming is available.
 In this case, the screen in Figure 3 displays.
 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.
