2019-2024 Nissan Altima 2.0L Engine Mount Control Module: Diagnosing Vibration and Programming
This guide covers the symptoms, replacement costs, and critical programming needs for the active engine mount control module in 2.0L VC-Turbo Altimas.
- Vibration in a 2.0L VC-Turbo Altima could be this module OR a serious engine bearing issue covered by NHTSA Recall 25V437. Always check for recalls first.
- A replacement module MUST be programmed to the vehicle's VIN using professional tools like the Nissan CONSULT-III Plus. This is not a simple plug-and-play part.
- The correct Nissan part number is 11280-6CB0A. An Infiniti module (11280-5NA0A) may not be directly compatible due to different firmware.
- Buying a used OEM module can save significant money, but ensure it's the correct part number and factor in the cost of professional programming.
Symptoms of a Failing Engine Mount Control Module
When the engine mount control module fails, the active mounts can no longer adjust properly. They may default to a firm setting or become completely inactive. This can lead to several noticeable symptoms.
Excessive Cabin Vibration
This is the most common symptom. You may feel a new or significantly increased vibration through the steering wheel, floor, or seats. The vibration is often most noticeable at idle (e.g., at a stoplight) or during specific RPM ranges while driving. Because the mounts are no longer actively canceling out the engine's vibrations, they are transferred directly into the vehicle's chassis.
Clunking or Thudding Noises
A failing module can lead to excessive engine movement. You might hear a distinct clunk, bang, or thud from the engine bay during hard acceleration, deceleration, or when shifting gears from Park to Drive or Reverse. This sound is the engine shifting and making contact with other components due to the mounts not holding it securely.
Check Engine Light and Error Codes
A failure in the module or its communication circuit can trigger a Check Engine Light. While research has not identified specific P-codes (Powertrain codes) exclusively for this module, failure may result in general communication codes (U-codes) or internal processor fault codes (P0605, P0606) if the module itself has an internal error. A technician with an advanced scan tool would be needed to check for communication errors with the module.
Important: The 2019-2020 Nissan Altima with the 2.0L VC-Turbo engine is part of a major safety recall (NHTSA ID: 25V437) for defective internal engine bearings that can cause engine failure. The symptoms of this serious issue include abnormal noises, vibrations, and check engine lights, which can easily be mistaken for a bad engine mount or module. Before replacing any parts for a vibration issue, have a Nissan dealer check your VIN to see if this recall applies to your vehicle.
Known Issues, TSBs, and Recalls
The most significant known issue for the 2019-2024 Altima's 2.0L VC-Turbo engine is NHTSA recall 25V437. This recall addresses a manufacturing defect in the engine's main bearings which can lead to noise, vibration, loss of power, and complete engine failure. Because the symptoms overlap directly with a failed engine mount system, it is critical to rule out this recall first. A Nissan dealer will inspect the engine for metal debris, and if none is found, the remedy for the 2.0L engine is an oil change. If damage is found, the engine may be replaced.
Buying a Used Engine Mount Control Module: What to Look For
Purchasing a used module can offer significant savings. Since aftermarket options are generally not available for this type of specific electronic controller, a used OEM part is a common and reliable choice. Here’s what to check:
- Match the Part Number Exactly: The correct part number for the 2019-2024 Nissan Altima is 11280-6CB0A. While the Infiniti QX50 uses a visually identical module with part number 11280-5NA0A for the same engine, it is unknown if the internal firmware is the same. To avoid compatibility and programming issues, stick to the exact Nissan part number.
- Physical Inspection: Carefully inspect the used module before purchase. Look for any signs of corrosion on the electrical connector pins, cracks in the plastic housing, or evidence of water intrusion. Any of these could indicate a damaged or non-functional unit.
- Source and Warranty: Buy from a reputable seller that offers a warranty. This gives you protection in case the part is dead on arrival or fails shortly after installation.
Programming and Installation Requirements
This is a critical consideration for this part. Based on Nissan's service procedures for other electronic modules from this era, it is highly likely that a replacement Engine Mount Control Module will need to be programmed to the vehicle.
Warning: You cannot simply swap this module and expect it to work correctly. The module needs to be synchronized with your vehicle's VIN and main computer systems.
This programming procedure requires specialized tools and software:
- Dealer Tool: A Nissan or Infiniti dealership can perform the programming using their proprietary CONSULT-III Plus diagnostic tool.
- Independent Shop: A qualified independent repair shop with an up-to-date J2534 pass-thru device and a subscription to Nissan's diagnostic software (NERS) can also perform this programming.
This is not a DIY-friendly job unless you have access to these specific tools and subscriptions. Factoring in the need for professional programming is essential when planning this repair.
Replacement Cost Comparison
The cost to replace the Engine Mount Control Module can vary significantly based on the part source and labor rates.
| Item | Estimated Cost | Notes |
|---|---|---|
| New OEM Module | $225 - $335 | Purchased from a Nissan dealership or online OEM parts retailer. |
| Used OEM Module | $45 - $100 | Commonly found at auto recyclers or on eBay. |
| Shop Labor (Installation & Programming) | $200 - $400 | Includes physical installation (approx. 0.5-1.0 hr) and the electronic programming procedure (approx. 1.0 hr). |
| Total (with Used Part) | $245 - $500 | Your most likely all-in cost. |
| Total (with New Part) | $425 - $735 | The high-end cost using all new parts at a dealership. |
Frequently Asked Questions (FAQ)
Does the engine mount control module need to be programmed?
Yes, it is almost certain that a replacement module needs to be programmed to your vehicle's VIN. This requires a dealer's CONSULT tool or equivalent professional equipment. Failure to program the module will likely result in it not functioning correctly.
Can I use an Infiniti QX50 module (11280-5NA0A) in my Altima?
While the module looks identical and is used on the same 2.0L VC-Turbo engine, it is not guaranteed to be a direct swap. The internal software may be different. To avoid potential issues, it is safest to use the exact Nissan part number 11280-6CB0A.
Is a vibrating engine always the module's fault?
No. On these specific vehicles, a vibration could also be a symptom of a failing engine bearing, which is covered under NHTSA recall 25V437. It could also be a physically failed engine mount (the rubber/fluid part), a transmission issue, or a simple engine misfire. Proper diagnosis is key.
What happens if I don't replace a bad module?
You will continue to experience excessive vibration and potential clunking noises. While the car may remain drivable, the constant vibration can cause discomfort and may put extra stress on other components, such as exhaust connections, wiring, and the other engine mounts.
