VERSA AND SENTRA; CVT VALVE BODY REPLACEMENT
WITH CONFIRMED DTC
This bulletin has been amended to update the Applied Vehicles and Parts Information.
Please discard the previous versions of this bulletin.
2012 – 2016 Versa Sedan (N17)
2014 – 2016 Versa Note (E12)
2013 – 2016 Sentra (B17)
APPLIED TRANSMISSION: CVT
APPLIED VEHICLES:
IF YOU CONFIRM

If one or more of the DTCs listed in Table A on page 2 are present in the
Transmission Control Module (TCM).
And

No other DTCs are present other than what are in Table A.
And

The diagnostic procedures in the Electronic Service Manual (ESM) for each DTC in
Table A, that is present in the TCM, has been performed and indicates that the CVT
assembly must be replaced.
NOTE: Do not replace CVT.
ACTION
Replace the CVT valve body assembly (control valve) with a unit from Parts Information
using the Service Procedure starting on page 3.
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 the 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.

Inspection and Adjustment
INSPECTION AFTER INSTALLATION
•
When replacing control valve, perform "ADDITIONAL SERVICE WHEN REPLACING CONTROL
VALVE OR TRANSAXLE ASSEMBLY". Refer to ESM for further information.
•
Check the CVT fluid level, condition and signs of leakage.
NOTE: Before performing Clutch Touch Point Learning.


Erase memory data.
Refer to the ESM, section TM – Transaxle & Transmission for further information.
CLUTCH TOUCH POINT LEARNING
CAUTION: If clutch touch point learning is not performed, you may feel shift shock when the auxiliary
transmission shifts.
Line Pressure Sensor learning
Set the parking brake, turn OFF the A/C, and then bring the engine to normal operating temperature
range.
 CVT fluid temperature over 122°F (50°C .
1.
2.
3.
4.
Start engine.
Shut OFF engine.
Wait for 30 seconds.
Repeat steps 1-3 two more times, and then proceed to Learning of Clutch pressure.
Clutch Pressure Learning (Vehicle with Neutral idle; 2012 Versa Sedan only)
1. Start engine.
2. Shift the CVT into P or N and allow the engine to idle for 1 min.
3. Shift the CVT into D, drive the vehicle to over 6 mph (10 km/h), and then stop vehicle (when
safe) and allow it to idle for 30 seconds.
Repeat step 3 one more time and then proceed to step 4.
4. Turn OFF engine.
5. Start engine.
6. Accelerate the vehicle from a stop to 28 mph (0 km/h to 45 km/h) at low throttle (5-10 deg) and
then stop vehicle (when safe).
7. Shut OFF engine.
8. Repeat steps 5-7 four more times.
Clutch Pressure Learning (Vehicle without Neutral idle; all other applied vehicles)
1. Start engine.
2. Shift the CVT into P or N and allow the engine to idle for 1 min.
3. Shift the CVT into D and accelerate the vehicle from a stop to 40 mph (0 km/h to 65 km/h) at low
throttle (5-10 deg).
4. Release the throttle and coast down to 18 mph (30 kp/h) or less and then brake to a stop.
5. When at a complete stop turn the engine OFF.
6. Repeat steps 3-5 four more times.
