P0965 on 2013-2020 Nissan Versa: CVT Judder, Solenoid, and Valve Body Fixes

What's Unique About the 2013-2020 Nissan VERSA

The Nissan Versa from this era is equipped with a Jatco-made CVT7 (model JF015E/RE0F11A) that is known for specific failure patterns. Unlike many other vehicles where a single solenoid can be replaced, on this platform, the solenoids are an integral and calibrated part of the transmission valve body. Fine metal particles, a byproduct of normal CVT operation, can contaminate the fluid and cause the delicate valves and solenoids within the valve body to stick or wear prematurely. As a result, Nissan's own Technical Service Bulletins (TSBs) often direct technicians to replace the entire valve body assembly, even for a single solenoid circuit code like P0965. This repair also requires complex reprogramming to make the new valve body communicate with the vehicle's computer, a step that is critical for proper function.

Diagnostic Flowchart

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

Generation note: This range covers two Versa generations: the second generation (N17; 2013-2019) and the third generation (N18; 2020). Both are known to experience this issue, though they use different CVT models (primarily the JF015E for the N17 and the JF020E for the N18). The diagnostic approach is similar as outlined in TSBs like NTB17-034k for the N17 and NTB22-021A for the N18, but part numbers for the valve body will differ.

Symptoms You May Notice

• Transmission judder (shaking, shuddering, or vibration), especially on acceleration.
🎬 Watch: What these CVT judder codes really mean for your car.
• Harsh or erratic shifting.
• Hesitation or a lack of power.
• Transmission slipping between gears.
• Transmission overheating.
• Vehicle enters 'limp mode,' limiting speed and engine RPM.
• Check Engine Light is illuminated.
• Increased fuel consumption.

Most Likely Causes

1. Faulty CVT Control Valve Body 🔴 High Probability → Shop Transmission Valve Body The integrated pressure control solenoids on the valve body are a known failure point in the Jatco CVTs used in these Versas. Fine metal debris in the fluid can cause valves to stick. Nissan TSBs NTB17-034k and NTB22-021A directly address this issue, providing a diagnostic path that frequently leads to valve body replacement. [⭐ MANUFACTURER TSB — highest authority]
   How to confirm: After ruling out fluid and wiring issues, a professional diagnosis with a scan tool is needed. The TSBs provide a detailed diagnostic tree that starts with checking for debris in the transmission pan. If minimal debris is found, the procedure points to valve body replacement.
   Typical fix: Replace the entire CVT control valve body assembly and reprogram the TCM with the new part's calibration data. This often involves a 'clutch point relearn' procedure.
   Est. part cost: $400-$1300
2. Low or Contaminated CVT Fluid 🟡 Medium Probability CVTs are very sensitive to fluid level and condition. Old, degraded, or incorrect fluid (non-NS-2/NS-3) can cause pressure regulation problems, leading to wear on internal components and triggering solenoid codes.
   How to confirm: Check the CVT fluid level and condition according to the manufacturer's procedure. Look for a dark color, burnt smell, or visible metal particles. The Jatco JF015E has two filters: an internal mesh filter and an external paper cartridge filter that should be inspected or replaced.
   Typical fix: Perform a CVT fluid drain and fill using the correct Nissan-specific CVT fluid (NS-2 or NS-3). Replacing the external cartridge filter is also recommended. 🎬 See this step-by-step guide for replacing fluid and both filters.
   Est. part cost: $75-$200
3. Wiring or Connector Issue ⚪ Low Probability
   How to confirm: Visually inspect the wiring harness and connectors going to the transmission for any signs of damage, corrosion, or loose connections. A multimeter can be used to check for continuity and proper resistance in the solenoid circuit, comparing readings to the factory service manual.
   Typical fix: Repair the damaged section of the wiring harness or clean/replace the faulty connector.
   Est. part cost: $10-$100

Rare But Worth Checking

• Failing Transmission Control Module (TCM): → Shop Transmission Assembly While rare, the TCM can fail internally, causing it to send false error codes. This should only be considered after all other possibilities, especially the valve body, have been thoroughly ruled out by a professional. Reprogramming the TCM is a standard step in many related TSBs and should be attempted before replacement.

Diagnosis Steps

1. Check for other stored DTCs to see if P0965 appears with other related transmission codes like P17F0, P0746, or P0846.
2. Inspect the level and condition of the CVT fluid. The fluid should be at the correct level and not appear burnt or contain excessive metal debris.
3. Visually inspect the transmission's main electrical connector and wiring harness for any signs of corrosion, damage, or loose connections.
4. If fluid and wiring are good, follow the diagnostic procedure in the relevant Nissan TSB (like NTB17-034k or NTB22-021A). This begins with dropping the transmission oil pan to inspect for metal debris on the magnets.
5. If excessive debris (large chunks or a thick metallic paste) is found, a complete CVT replacement is likely necessary, and a dealer consultation is required for authorization.
6. If only fine metallic sludge is found (which is considered acceptable), the TSB points toward replacing the control valve body.
7. After replacement, the new valve body's calibration data must be written to the TCM, and several relearn procedures (like Clutch Point Learning) must be performed using a compatible scan tool.

Related Codes That Often Appear With This One

• P0746 — Relates to Pressure Control Solenoid 'A', often failing along with Solenoid 'B'. Both are mentioned together in TSBs NTB22-021A and NTB17-034k. [⭐ MANUFACTURER TSB — highest authority]
• P17F0 — This is a Nissan-specific code for 'CVT Judder'. It frequently appears with P0965 as the judder is a primary symptom of the pressure control failure. The diagnostic flowcharts in the TSBs are often initiated by the presence of this code. [⭐ MANUFACTURER TSB — highest authority]
• P0846 — This code indicates a fault with the Transmission Fluid Pressure Sensor 'B'. Since the sensor and solenoid work together to regulate pressure, a fault in one can be flagged with the other. It is cited in TSB NTB17-034k. [⭐ MANUFACTURER TSB — highest authority]
• P0776 — This code is for 'Pressure Control Solenoid 'B' Performance/Stuck Off', indicating a mechanical rather than purely electrical issue with the same solenoid. It is mentioned in TSB NTB22-021A. [⭐ MANUFACTURER TSB — highest authority]

Technical Service Bulletins (TSBs) & Recalls

• NTB22-021A: Mentions P0965 stored in the TCM for 2020 models and provides a detailed flowchart for diagnosing and repairing the CVT, which may involve valve body or full transmission replacement.
• NTB17-034k: Links CVT judder and P0965 for 2013-2017 Versa models, detailing the inspection of the transmission pan for debris as a critical step before replacing the valve body.
• NTB15-037f: An earlier bulletin for 2012-2015 Versa and Sentra models that explicitly states to replace the CVT valve body assembly if DTC P0966 or P0967 (related to Solenoid 'B' circuit) are present, instead of replacing the whole transmission.

Platform-Specific Known Issues

• A complaint filed with the NHTSA (ODI #11296924) for a 2015 Versa reported stuttering and the presence of code P0965 along with others, leading to a dealer diagnosis. [ Owner complaints]
• Nissan has issued multiple Technical Service Bulletins (TSBs) like NTB17-034k and NTB22-021A that group P0965 with CVT judder and other pressure-related codes, outlining a specific diagnostic path that often results in valve body or full CVT replacement. [⭐ MANUFACTURER TSB — highest authority]
• In a forum discussion, an owner of a 2012 Versa confirmed that replacing the valve body successfully fixed their transmission issues, which included juddering and high RPMs associated with a related trouble code.

Mechanic-Grade Diagnostic Values

• Resistance of Pressure Control Solenoid 'B' (Primary Pressure Solenoid) — expected: 5.3 Ω at 20°C (68°F), 6.0 Ω at 50°C (122°F), 6.7 Ω at 80°C (176°F).. Failure: A significantly higher or lower resistance reading, or an open circuit (infinite resistance).

Hidden / Shadow Codes Worth Checking

• P17F0 / P17F1 (CVT Judder): These are Nissan-specific 'hard codes' that are directly tied to the TCM's calibration data for the valve body solenoids. They indicate a mismatch between the expected and actual performance of the solenoids. (see via These codes will appear as 'Current' or 'Active' on a standard OBD-II scanner but cannot be erased by a simple 'Clear Codes' command. They will only move to 'History' status after a successful valve body recalibration, at which point they can be cleared.)

Scan Tool Commands That Help

• Nissan CONSULT-III plus: WRITE IP CHARA (Write Inherent Performance Characteristics) — This is mandatory after replacing the CVT valve body or the entire CVT assembly. It writes the unique calibration data from a QR code or CD supplied with the new part to the TCM. Failing to do this will prevent 'hard codes' like P17F0 from being cleared and will result in continued performance issues.
• Nissan CONSULT-III plus: Auxiliary gearbox clutch point learning — This procedure must be performed after replacing the valve body to allow the TCM to relearn the clutch engagement points. TSBs instruct this to be performed twice in a row for proper calibration.
• Nissan CONSULT-III plus: ERASE MEMORY DATA — This function is used to clear adaptive learning values from the TCM as part of the valve body replacement procedure, before performing new relearns.

Wiring & Ground Locations

• Transmission Case Connector (JF015E/RE0F11A) — The main electrical connector on the outside of the CVT case.. Pin 3 is the control circuit for the Primary Pressure Solenoid 'B'. To test the solenoid's resistance, check between Pin 3 and the metal transmission case itself, as the solenoid is internally grounded to the case.

OEM Part Supersession History

• 31705-3JX8A → 31705-3JX5D — Part revision or update by the manufacturer.

Model Year Variations Within This Range

• 2013-2019: Some Versa Note models were equipped with a START-STOP system. The valve body for these models is different from those without it. Part number 31705-3JX5D is specified for models WITHOUT the START-STOP system. Verifying the correct part by VIN is critical.
• 2017-2019: Later models within the second generation may use a different valve body assembly, such as part number 31705-X428A, indicating a mid-cycle change in the transmission components.
