P0746 on 2017 Nissan Versa Note: CVT Pressure Solenoid Causes and Fixes

What's Unique About the 2017-2017 Nissan VERSA NOTE

The 2017 Versa Note uses a Jatco JF015E (Nissan designation RE0F11A) CVT, which is known for having issues related to the valve body and pressure control solenoids. This specific CVT model has a unique two-speed auxiliary gearbox design to improve efficiency, but it is also highly sensitive to fluid contamination. Unlike many other vehicles where P0746 might be a simple electrical fault, on this Nissan platform, it is very frequently a mechanical failure inside the transmission. Nissan has issued multiple Technical Service Bulletins (TSBs), most notably NTB17-034k, acknowledging that this code is often accompanied by a 'CVT judder' and points towards a systemic problem with fluid contamination and valve body wear, rather than an isolated component failure.

Diagnostic Flowchart

Tap your situation to follow the diagnostic path that matches what you're seeing on this vehicle.

Symptoms You May Notice

• Transmission judder (shaking, shuddering, or vibration), especially on light acceleration.
• Hesitation on acceleration.
• Engine RPMs surging or flaring without an increase in speed.
• Lack of power or feeling sluggish.
• Vehicle may enter 'limp mode' with severely limited speed.
• Harsh or abrupt gear engagement.
• Inability to shift or move the vehicle.
• Check Engine Light is on.

Most Likely Causes

1. Faulty CVT Valve Body / Pressure Control Solenoid 🔴 High Probability → Shop Transmission Clutch Pressure Control Solenoid This is a well-documented failure point on the Jatco JF015E CVT. Fine metallic debris from normal wear contaminates the CVT fluid, clogging the intricate passages in the valve body and causing the solenoids to stick or fail. The design is very sensitive to fluid cleanliness.
   How to confirm: A technician will use a scan tool to monitor commanded vs. actual line pressure. A significant deviation points to a hydraulic issue. Physical inspection of the transmission pan magnets for excessive metallic debris is also a key indicator.
   Typical fix: Replacement of the entire CVT valve body assembly. 🎬 See how a valve body fix resolves the common CVT shudder. Solenoids are rarely replaced individually as the issue is often contamination within the valve body itself or wear in the solenoid bores.
   Est. part cost: $900-$1500
2. Low or Contaminated CVT Fluid 🟡 Medium Probability Old, burnt, or incorrect fluid cannot maintain the required hydraulic properties, leading to poor lubrication and overheating. This accelerates wear and creates the debris that clogs solenoids and filters. The use of anything other than genuine Nissan NS-3 fluid is a common cause of problems.
   How to confirm: Check the CVT fluid level and condition. The fluid should be a translucent green (for Nissan NS-3) and not dark, burnt-smelling, or full of particles. This check must be done according to the manufacturer's procedure, as there is no traditional dipstick.
   Typical fix: Perform a CVT fluid drain and fill with genuine Nissan CVT Fluid NS-3. If the fluid is heavily contaminated, this may not solve the problem if the valve body is already damaged.
   Est. part cost: $20-$25 per quart (typically requires 4-5 quarts)
3. Clogged CVT Fluid Filters ⚪ Low Probability The CVT has both an internal pan filter (screen) and an external cartridge filter. If they become clogged with debris, fluid flow is restricted, starving the pump and causing low line pressure. This can sometimes be the sole cause if the valve body isn't yet damaged.
   How to confirm: This is usually discovered during a valve body replacement or a thorough fluid service. The external filter can be inspected and replaced more easily. A severely clogged internal screen found when dropping the pan is a clear indicator.
   Typical fix: Replace the external cartridge filter and clean or replace the internal pan filter screen. This is typically done in conjunction with a fluid change.
   Est. part cost: $30-$80

Rare But Worth Checking

• Complete Internal CVT Failure: In some cases, P0746 is a symptom of a larger failure, such as a failing oil pump flow control valve or a damaged belt/pulley set. If the transmission pan contains large, shiny metal shards (not just fine paste on the magnets), the entire CVT unit will likely need replacement.
• Faulty Transmission Control Module (TCM): → Shop Transmission Assembly While possible, a faulty TCM is not a common cause for this code on this vehicle. The mechanical and hydraulic components should be thoroughly checked before condemning the TCM.

Diagnosis Steps

1. Verify the code with a reliable OBD-II scanner.
2. Check for any Nissan Technical Service Bulletins (TSBs), specifically NTB17-034k, related to your vehicle's VIN.
3. Inspect the level and condition of the CVT fluid. Note any burnt smell or dark discoloration. This requires a specific procedure as there is no dipstick.
4. Use an advanced scan tool to monitor live data for commanded versus actual transmission line pressure.
5. Drop the transmission pan and inspect the magnets for metal debris. A fine, dark paste is typical wear, but large or shiny metal flakes indicate severe internal damage.
6. Inspect the wiring harness and connectors leading to the transmission for any damage or corrosion.
7. If fluid is clean, wiring is good, but pressure is low, the primary suspect is the CVT valve body assembly.
8. Follow the TSB repair procedure, which will likely guide you to replace the valve body or the entire CVT assembly depending on diagnostic findings.
9. After repair, perform the 'clutch point relearn' procedure using a compatible scan tool.

Platform-Specific Known Issues

• Nissan has issued multiple versions of Technical Service Bulletin NTB17-034 (ending in k, i, g, etc.) for 'CVT Judder' and DTC P0746 on 2014-2017 Versa Notes. This confirms it is a widespread, recognized issue by the manufacturer. [Bulletin #NTB17-034k, #NTB17-034i, #NTB17-034g]
• Due to the prevalence of this and other CVT issues, Nissan extended the warranty on many CVT transmissions, including those in some Versa Note models, from 5 years/60,000 miles to 7 years/84,000 miles.

Mechanic-Grade Diagnostic Values

• Pressure Control Solenoid 'A' Resistance — expected: Approximately 5.3 Ω at 68°F (20°C). Failure: A reading significantly higher or lower than the specification, or an open/short circuit.
• Pressure Control Solenoid 'A' Duty Cycle (Live Data) — expected: Varies with shift demand and engine load.. Failure: A constant 0% duty cycle for Solenoid 'A' indicates a stuck-off condition.
• Commanded vs. Actual Line Pressure (Live Data) — expected: Actual pressure should closely follow commanded pressure.. Failure: If 'Measured Line Pressure' lags significantly below 'Pressure Commanded' (e.g., >15% deviation) under load, it indicates a hydraulic leak, blockage, or weak solenoid.

Scan Tool Commands That Help

• Nissan CONSULT or compatible professional scan tool: ERASE LEARNING VALUE — This must be performed after replacing the valve body or entire CVT assembly to clear the old adaptive learning values from the Transmission Control Module (TCM).
• Nissan CONSULT or compatible professional scan tool: Auxiliary gearbox clutch point learning — This is a required relearn procedure after clearing trouble codes or replacing major components like the valve body. It allows the TCM to relearn the clutch engagement points for smooth shifting.

• Manual Procedure (No Scan Tool): Manual Auxiliary Gear Box Clutch Point Learn Procedure — A detailed, 21-step manual process involving specific ignition cycles and driving patterns to perform the clutch point relearn when a compatible scan tool is not available.

Wiring & Ground Locations

• Transmission Case Ground — The transmission case itself.. The pressure control solenoids inside the JF015E transmission are internally grounded to the transmission case. When testing solenoid resistance from the main harness connector, the case should be used as the ground reference point. A poor ground for the entire transmission assembly could cause erratic electrical issues.
• OBD-II Port — Under the driver's side dashboard, to the right of the hood release handle.. This is the connection point for the OBD-II scanner required to read the P0746 code and monitor live transmission data for diagnosis.

Real Owner Repair Stories

• AliExpress User/Article (2013 Nissan Sentra with over 142,000 miles (uses the same JF015E/RE0F11A transmission)) — Hesitating between gears during light acceleration, especially after highway driving. OBD-II scanner repeatedly showed P0746.
  ❌ Tried (didn't work) Initially suspected low fluid or a sensor glitch.
  ✅ What actually fixed it After inspecting the valve body and finding thick black residue and visible scoring on spool-valve grooves, the entire valve body assembly was replaced with a new unit that included all pre-installed solenoids. This resolved the P0746 code permanently.

OEM Part Supersession History

• 31705-3JX8A → 31705-3JX5D — Part revision by the manufacturer. The original part is now discontinued.
  Heads up: The valve body for the Jatco JF015E reportedly had a design change around the 2016 model year. Early (pre-2016) and late (2016+) versions are not interchangeable. It is critical to verify the correct part for a 2017 vehicle.
