Understand the symptoms of a failing ABS sensor in your Altima and how to choose the right replacement part.
- A bad ABS sensor will disable your Altima's anti-lock brakes and traction control systems.
- Use an ABS-capable scan tool to identify which specific wheel sensor has failed before buying parts.
- For best results, choose a high-quality aftermarket brand like Delphi or Standard Ignition.
- Replacement is a simple DIY job for many, requiring basic tools and costing significantly less than a shop visit.
Understanding a Failing ABS Sensor in Your Altima
When an ABS wheel speed sensor fails on your 2020-2025 Nissan Altima, it directly impacts your car's safety systems. Because the sensor provides speed data to multiple computers, a single faulty sensor can trigger several warning lights on your dashboard, including the ABS and traction control lights. While your regular brakes will still work, the anti-lock and stability control features will be disabled. This means your wheels could lock up during a panic stop, increasing the risk of skidding.
Known Issues: Phantom Braking
While not directly caused by a simple ABS wheel speed sensor failure, some 2020 Altima owners have reported issues with the Automatic Emergency Braking (AEB) system engaging unexpectedly, a phenomenon sometimes called "phantom braking". This is often related to the more complex forward-facing radar sensors, but it highlights the importance of maintaining all components of your Altima's braking and safety systems. If you experience any unexpected braking, have your vehicle inspected by a professional immediately.
Choosing the Right Aftermarket ABS Sensor
For a vehicle as new as the 2020-2025 Altima, the choice between Original Equipment (OEM) and aftermarket parts can be confusing. OEM sensors are identical to the part your car came with from the factory. Aftermarket parts are made by other companies to fit and function like the original. For electronic parts like ABS sensors, quality can vary significantly between brands.
Here’s a breakdown of the available aftermarket brands:
- Top Tier (OEM Quality): Delphi is a well-respected brand that often manufactures original parts for car companies. Choosing a Delphi sensor is the closest you can get to OEM quality, ensuring reliable performance and longevity.
- Mid-Grade (Reliable Aftermarket): Standard Ignition (Standard Motor Products) is a long-standing brand in the aftermarket with a reputation for producing reliable parts. They offer a good balance of quality and cost for your Altima.
- Standard/Economy Tier: Holstein provides functional replacement parts that meet basic requirements. These sensors can be a cost-effective solution, and often come with necessary hardware like clips and grommets to simplify installation.

Frequently Asked Questions
Can I replace just one ABS sensor?
Yes. You only need to replace the specific sensor that has failed. An ABS-capable scan tool will identify which sensor at which wheel is causing the problem.
Is replacing an ABS sensor a difficult DIY job?
For someone with basic tools, it is a feasible DIY repair. 🎬 Watch this step-by-step walkthrough of an Altima ABS sensor replacement. The sensor is typically held in by a single small bolt (usually 10mm) at the wheel hub. The most difficult part can be removing the old sensor if it is seized by rust. After replacement, the ABS light may turn off on its own after a short drive, or it may need to be cleared with a scan tool.
