⚠️ Drivable, but... — Yes, but your anti-lock braking and traction control systems will not function, increasing the risk of skidding in an emergency stop.
Key Takeaways
  • Verify your Sport Trac's generation (2001-05 vs. 2007-10) and drivetrain (2WD/4WD) before ordering.
  • A bad sensor will disable your ABS and traction control; your normal brakes will still work, but with reduced safety in emergencies.
  • Premium aftermarket brands like Delphi, SKF, and Standard Ignition offer a good balance of quality and price.
  • The most common symptom is the ABS light on the dash, but a diagnostic scan is needed to confirm which sensor has failed.
The ABS wheel speed sensor on your Ford Explorer Sport Trac is a critical part of its braking system. It constantly measures how fast each wheel is spinning and sends this information to the anti-lock brake (ABS) computer. This data allows the computer to detect when a wheel is about to lock up during hard braking, pulsing the brakes to prevent skidding and maintain steering control. The same information is used by the traction control and stability control systems to prevent wheel spin and keep the truck stable in slippery conditions. A faulty sensor will disable these important safety features.

Is a Bad ABS Sensor Dangerous?

When an ABS sensor fails on your Explorer Sport Trac, your dashboard will light up with an ABS warning light, and likely the traction control light as well. While your normal brakes will still work, the anti-lock and traction control safety systems will be turned off. This means in an emergency stop or on a slippery road, your wheels can lock up, increasing stopping distance and causing a loss of steering control. It is important to address the issue to restore these safety features.

Critical Ordering Information: Check Your Generation

The 2001-2010 Ford Explorer Sport Trac covers two different vehicle generations. Parts are not interchangeable between them.

Always verify the exact model year, drivetrain (2WD or 4WD), and sensor location (front left, front right, or rear) before ordering. The rear sensor on some earlier models is a single unit mounted on the differential, while others have sensors at each wheel.

Choosing the Right Aftermarket ABS Sensor

When replacing your ABS sensor, you have several options beyond the expensive dealership part. Here’s a breakdown of the brands available to help you make an informed choice.

OEM (Original Equipment Manufacturer)

  • Motorcraft: This is Ford's own brand. It guarantees a perfect fit and original performance. While it's the most reliable choice, it is also typically the most expensive.

Premium Aftermarket Brands

These brands are known for producing high-quality parts that meet or exceed OEM standards. They are an excellent balance of price and quality.

  • SKF: A top-tier brand, famous for bearings. Since the sensor often works with or is part of the wheel bearing hub, their quality is trusted.
  • Delphi: A well-respected OEM supplier for many car manufacturers. Delphi sensors are known for their reliability and are a solid choice for your Ford.
  • Standard Ignition (SMP): A long-standing, reputable manufacturer of automotive sensors and electronics.

Standard & Economy Aftermarket Brands

These brands offer a significant cost saving, making them a popular choice for budget-conscious repairs. However, quality can sometimes be inconsistent.

  • Dorman: Dorman provides a huge range of affordable parts. For a component like an ABS sensor, their quality is often considered hit-or-miss. It may work perfectly, but some owners and mechanics report premature failures with their electronic parts.
  • Hella, Holstein, Vemo, URO Parts, Walker Products: These brands offer viable alternatives, often at a very low price point. They can be a good value, but may not have the same long-term durability as premium brands.

Pro Tip: Check for Deeper Issues

On some Explorer models, metal shavings from failing bearings inside the rear differential can stick to the magnetic rear ABS sensor, causing it to fail. If you are replacing a rear differential-mounted sensor, it's wise to check the differential fluid. If it's full of metal particles, you have a bigger problem that will just ruin the new sensor.

Cost of Replacing an ABS Sensor

The cost can vary based on the brand you choose and whether you do the work yourself. The job is simple enough for a DIY mechanic with basic tools.

Part/Service Estimated Cost
OEM Motorcraft Part $75 - $150+
Aftermarket Part $22 - $140
Shop Labor $95 - $160
Total Professional Repair $120 - $300+

Frequently Asked Questions (FAQ)

Can I replace just one ABS sensor?

Yes. You only need to replace the sensor that has failed. A proper diagnostic scan tool can read the ABS module's trouble codes to tell you exactly which wheel sensor is reporting a fault.

What's the difference between front and rear sensors?

Front and rear sensors are not interchangeable. They have different mounting brackets, wire lengths, and connectors. On some Sport Trac models, especially earlier ones, the rear uses a single sensor mounted on the rear differential, while the front has a sensor at each wheel.

Could something else cause my ABS light?

Yes. While a bad sensor is the most common cause, the light can also be triggered by a broken or corroded wire leading to the sensor, a damaged tone ring on the axle or wheel bearing, a bad ABS control module, or even low brake fluid. A diagnostic scan is the best way to pinpoint the problem.

Why did my new aftermarket brake rotor cause an ABS problem?

This is a known issue. The ABS sensor reads a notched or toothed wheel called a "tone ring." Some aftermarket brake rotors or wheel hubs come with a new tone ring pressed on. If this ring has a different number of teeth or spacing than the original, it will send an incorrect signal to the ABS computer, causing the system to malfunction, often feeling like a pulsing brake pedal.
