NISSAN; MIL ON WITH DTC P0139 AND/OR P0159 STORED
This bulletin has been amended. The Title and APPLIED VEHICLES have been revised.
Table A in the SERVICE PROCEDURE has been updated. Please discard all previous versions.

APPLIED VEHICLES: 2012 - 2014 370Z (Z34)
2012 - 2014 370Z Roadster (Z34)
2013 - 2014 Frontier (D40) with VQ40DE (6-cyl) engine ONLY
2013 - 2014 Xterra (N50)

IF YOU CONFIRM:
The MIL is ON and one or both of the following DTCs are found stored in the ECM:
•

P0139 (heated oxygen sensor 2 (B1) circuit slow response)

•

P0159 (heated oxygen sensor 2 (B2) circuit slow response)

ACTION:
1. Confirm this bulletin applies.
•

Compare the vehicle’s current ECM part number to those listed in Table A (see
page 5).

2. If the ECM part number does not match one listed in Table A, this bulletin does not
apply. Go back to ASIST for further diagnostic and repair information.
3. If this bulletin applies, reprogram the ECM.

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
•

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.

Preparation for Reprogramming
•

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

NOTE:
o After ECM reprogramming is complete, you will be required to perform
Throttle Valve Closed Position, Idle Air Volume Learn (IAVL), and Accelerator
Closed Position.
o The above conditions are required for the IAVL to complete.
CAUTION:
•

Connect the GR8 to the vehicle battery. The vehicle battery voltage must stay
between 12.0V and 15.5V during reprogramming, or 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.

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).

Step 6A: Current 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, this bulletin applies. Continue with the reprogramming
procedure.

•

If there is not a match, this bulletin does not apply. Return to ASIST for
further diagnostic and repair information.

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

NOTES:
•

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.
