P0841 on 2015-2017 Nissan JUKE: CVT Pressure Sensor, Valve Body, and Transmission Guide

What's Unique About the 2015-2017 Nissan JUKE

For the 2015-2017 Juke (excluding NISMO RS models), P0841 is rarely a simple sensor issue. These vehicles use the RE0F10D CVT, which has a well-documented failure pattern. Nissan issued Technical Service Bulletin (TSB) NTB20-091A, which groups P0841 with several other codes (P0776, P17F0, etc.). This TSB points directly to a faulty CVT control valve (valve body) or more severe internal transmission damage as the root cause. Unlike other vehicles where P0841 might be a wiring or fluid issue, on the Juke it's a strong indicator of a significant internal transmission problem requiring a specific, documented repair procedure that starts with checking for metal debris in the oil pan.

Diagnostic Flowchart

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

Symptoms You May Notice

• Check Engine Light is on
• Vehicle enters 'limp mode' (reduced power and acceleration)
• Harsh or jerky shifting sensations, or a noticeable 'judder' during acceleration.
• Slipping or hesitation during acceleration.
• Engine RPM revs high or fluctuates without a corresponding increase in speed.
• Transmission may feel stuck in a low or high 'gear'
• Whining or clunking noises from the transmission.

Most Likely Causes

1. Faulty CVT Control Valve (Valve Body) 🔴 High Probability This is a well-documented failure for this CVT (model RE0F10D). Nissan TSB NTB20-091A directly addresses this, recommending valve body replacement as the primary fix if no significant metal debris is found in the pan. The pressure sensor is an integral part of this assembly.
   How to confirm: A technician will follow the diagnostic procedure in TSB NTB20-091A, which involves checking for other codes and removing the transmission oil pan to inspect the magnets for debris. If only a fine metallic paste is found (not large chips or flakes), the valve body is the likely culprit.
   Typical fix: Replace the CVT control valve assembly kit and reprogram the TCM. The kit typically includes the valve body, a new oil strainer, pan gasket, and various seals.
   Est. part cost: $800-$1500
2. Internal CVT Damage (Belt and/or Pulley Failure) 🟡 Medium Probability The same TSB (NTB20-091A) outlines an inspection for CVT belt slippage and damage. These CVTs are known to suffer from premature wear of the steel belt and pulleys, which generates metallic debris that contaminates the system and leads to pressure faults and eventual failure.
   How to confirm: During the diagnostic process, a technician will remove the transmission oil pan and inspect the fluid and magnets. Finding excessive metallic debris (chunks, flakes, or a thick, gritty paste) is definitive evidence of belt or pulley damage. The TSB also details a secondary inspection using a borescope to look for scuffing on the belt itself.
   Typical fix: Complete replacement of the CVT assembly with a new or remanufactured unit. Some specialized shops may perform a sub-assembly repair, but a full replacement is the more common and warrantied solution from dealerships.
   Est. part cost: $3000-$5000
3. Low or Contaminated CVT Fluid ⚪ Low Probability
   How to confirm: Check the level and condition of the CVT fluid. The fluid should be at the correct level, clear green, and not smell burnt. Note: The Juke does not have a traditional dipstick, so this check must be performed by a qualified technician using the overflow plug at a specific fluid temperature.
   Typical fix: Perform a CVT fluid drain and fill using only genuine Nissan NS-3 fluid. This is highly unlikely to fix P0841 on this vehicle if it's the only action taken, but it is a necessary first step in any diagnosis.
   Est. part cost: $150-$250

Rare But Worth Checking

• Wiring Harness Damage: While less common than internal failures on this model, wiring to the transmission connector could be damaged, causing a signal issue. This should be inspected before condemning expensive internal parts.
• Faulty Transmission Control Module (TCM): It is rare for the TCM itself to fail, but it's a remote possibility if all other causes have been ruled out. The TCM is integrated with the valve body on this transmission, so it is replaced as part of the valve body assembly.

Diagnosis Steps

1. Scan the TCM for all stored DTCs. Note if P0841 is present with any of the codes listed in TSB NTB20-091A (P17F0, P17F1, P0776, P2813, P1715).
2. Check the CVT fluid level and condition. This requires a specific procedure using the overflow plug at a specified temperature, as there is no dipstick.
3. Reference Nissan TSB NTB20-091A. This is the most critical step and provides the official diagnostic flowchart.
4. Remove the CVT oil pan. Carefully inspect the fluid and the pan magnets for excessive metal debris (anything more than a fine, dark paste).
5. If significant debris (chunks, flakes, shiny metallic particles) is found, this indicates belt/pulley damage. The CVT assembly requires replacement.
6. If little to no debris is found, the recommended repair is to replace the control valve (valve body) assembly kit.
7. After replacing the valve body or transmission, install a new oil strainer, pan gasket, and refill with genuine Nissan CVT Fluid NS-3.
8. Perform the necessary TCM reprogramming and relearn procedures as outlined in the service manual using a compatible scan tool.

Related Codes That Often Appear With This One

• P17F0 — Indicates a CVT judder/judgement issue, directly linked to the valve body and internal mechanics. It is cited in the same TSB (NTB20-091A) as a primary companion code.
• P17F1 — Also related to CVT judder and cited in TSB NTB20-091A as part of the same known issue, pointing towards a valve body or internal inspection.

• P2813 — Pressure Control Solenoid 'G' Performance. This is another valve body solenoid code listed in TSB NTB20-091A.
• P1715 — Input Speed Sensor Primary fault. This can be triggered by the erratic mechanical behavior caused by the valve body or belt slip. It is also listed in TSB NTB20-091A.

Technical Service Bulletins (TSBs) & Recalls

Platform-Specific Known Issues

• The Continuously Variable Transmission (CVT) in this generation of Juke, model RE0F10D, is subject to a high failure rate of the control valve body, as documented in TSB NTB20-091A.
• This TSB groups P0841 with several other codes, indicating a complex internal failure rather than a simple sensor fault. The diagnostic path almost always leads to replacing either the valve body or the entire transmission.
