Nissan Altima ABS Wheel Speed Sensor Guide for 2015-2019 Models
If the ABS and traction control lights are on in your Altima, a bad wheel speed sensor is the most likely cause.
- An illuminated ABS and Traction Control light on your 2015-2019 Altima is the number one sign of a failed wheel speed sensor.
- Your regular brakes will still work, but the anti-lock safety feature will be disabled until the sensor is replaced.
- This is a common DIY repair; the front sensors are easier to replace than the rear ones.
- Get the trouble codes read before buying a part to ensure you are replacing the correct sensor at the correct wheel location.
Understanding the ABS Wheel Speed Sensor in Your 2015-2019 Altima
A faulty ABS wheel speed sensor is a common issue on the Nissan Altima. These sensors live in a harsh environment at the wheel hub, exposed to water, dirt, and road debris. A single bad sensor can turn off your anti-lock brakes and traction control, lighting up your dashboard with warning lights. This guide will help you understand the symptoms, choose the right aftermarket replacement part, and know what to expect for repair costs.
Symptoms of a Failing ABS Sensor
When a wheel speed sensor fails, your Altima will give you clear warning signs. The car's computer detects that it's not receiving correct data from one of the wheels and shuts the system down as a precaution.
- ABS Warning Light: This is the most common symptom. The 'ABS' light on your dashboard will stay on.
- Traction Control Light: The traction control system (TCS) or Vehicle Dynamic Control (VDC) light will also likely illuminate, as it uses the same sensors as the ABS.
- Disabled Safety Systems: With the warning lights on, your anti-lock braking and traction control systems are turned off. Your regular brakes will still work, but you won't have the added safety of ABS in an emergency stop.
- Braking Issues: In some rare cases, you might feel a pulsating brake pedal or notice that it takes longer to stop.
Known Issues & Technical Service Bulletins (TSBs)
While there are no specific recalls for this part on the 2015-2019 Altima, Nissan has issued technical service bulletins (TSBs) for earlier models regarding ABS sensor diagnosis. TSB NTB10-102a advises technicians to perform a full diagnosis and not just replace a sensor based on a trouble code alone. This highlights the importance of confirming the failure, as issues with wiring or contamination on the sensor's magnetic ring can also cause problems.
Choosing the Right Aftermarket ABS Sensor
You don't have to buy an expensive OEM sensor from the dealership. Aftermarket brands offer a wide range of quality and price points. For a critical safety component like this, it's best to avoid the absolute cheapest options and choose a reputable brand.
- Premium Aftermarket (e.g., Delphi, Standard Ignition): These brands are often original equipment (OE) suppliers for many car manufacturers. They offer high-quality parts that are engineered to meet or exceed OEM specifications. Parts from brands like Standard Ignition often include features like protective wire sleeves to prevent damage. Delphi is another well-regarded OE-quality brand.
- Quality Aftermarket (e.g., Holstein): Brands like Holstein specialize in sensors and offer a good balance of quality and price. They use quality materials and often provide warranties, like Holstein's 3-year/36,000-mile warranty, which shows confidence in their product.
- Budget-Friendly (e.g., Vemo, other store brands): While some brands like Vemo are more focused on European vehicles, they are available for the Altima. These can be a viable option if budget is the main concern, but may not have the same long-term durability or perfect fit as premium brands.
Pro Tip: Check the Correct Location
Your Altima has four ABS sensors: one at each wheel. The front sensors are different from the rear sensors, and the left and right sides may also be different. Before ordering, have your car scanned for trouble codes (many auto parts stores do this for free). The code will tell you which specific sensor has failed (e.g., 'Right Front Wheel Speed Sensor Circuit Malfunction'). 🎬 Watch how to diagnose and reset your ABS light. This ensures you order the correct part the first time.
Cost to Replace a Nissan Altima ABS Sensor
The cost can vary depending on whether you do it yourself or take it to a shop. The part itself is the main variable.
| Item | Cost Range |
|---|---|
| New OEM Part | $190 - $290 |
| New Aftermarket Part | $56 - $333 |
| Shop Labor | $65 - $100 |
| Total Professional Repair | $250 - $380+ |
Frequently Asked Questions (FAQ)
Can I drive my Altima with the ABS light on?
Yes, but with caution. Your primary braking system will still work, but the anti-lock and traction control safety features are disabled. It is recommended to get the sensor replaced as soon as possible to restore these important safety functions.
Is it hard to replace an ABS sensor on a 2015-2019 Altima?
No, it is a relatively easy job for a DIYer with basic tools. The front sensor is held by a single 10mm bolt and a few clips 🎬 See this walkthrough for replacing your front ABS sensors. for the wire. The rear sensor is also held by one bolt but may require removing the brake caliper to gain access, making it slightly more difficult. 🎬 Watch this guide to replacing the rear wheel speed sensor. The main challenge can be if the old sensor is rusted into the wheel hub.
Do I need to replace all four sensors at once?
No. You only need to replace the sensor that has failed. A diagnostic scan will produce a trouble code that points to the specific sensor that needs replacement.
Can I just clean the ABS sensor?
Sometimes, the sensor tip can get covered in metallic debris or dirt, causing a bad reading. You can try removing the sensor and cleaning it with a rag and brake cleaner. Also, inspect the toothed ring (tone ring) it reads from for debris or damage. If cleaning the sensor doesn't turn the light off after driving, the sensor itself has likely failed and needs to be replaced.
