Ford Explorer ABS Wheel Speed Sensor: A Guide for 2012-2023 Models
Understand why your ABS and AdvanceTrac lights are on and how to choose the right replacement sensor for your Explorer.
- A bad ABS sensor is the most common cause of the 'ABS' and 'Service AdvanceTrac' warning lights on a 2012-2023 Explorer.
- The vehicle's primary braking system will still work, but the anti-lock and stability control safety features will be disabled.
- Replacement is a simple DIY job for most, requiring basic tools. The biggest challenge is often removing the old sensor if it's seized with rust.
- While cheaper aftermarket sensors are available, choosing a reputable brand like Delphi or Standard Ignition can prevent early failure and repeat repairs.
Symptoms of a Failing ABS Sensor in a Ford Explorer
When an ABS wheel speed sensor starts to fail on your 2012-2023 Explorer, the vehicle's computer will usually let you know right away. The most common sign is a combination of warning lights on your dashboard.
- ABS Warning Light: This is the most direct indicator. A continuously lit ABS light means the system has detected a fault and has likely disabled itself.
- Service AdvanceTrac Light: Because the stability control system (AdvanceTrac) relies on wheel speed data, a bad sensor will trigger this warning message.
- Traction Control Light: The light showing a car with squiggly lines will often illuminate, as traction control also needs accurate wheel speed readings to function.
- Erratic Braking (Less Common): In some instances, before the system shuts down, you might feel the brake pedal pulsate at low speeds as the ABS incorrectly activates. However, it's more common for the system to just turn off.
- Speedometer Issues: In some vehicles, a faulty ABS sensor can cause the speedometer to behave erratically or stop working altogether.
What Causes Them to Fail?
ABS sensors live in a harsh environment near the wheels. Common causes of failure include damage to the sensor wiring, corrosion on the sensor or its connector, or an accumulation of metallic debris on the magnetic tip from brake dust. Sometimes, the toothed "tone ring" that the sensor reads can become damaged or cracked, leading to a bad signal.
Choosing the Right Aftermarket ABS Sensor
When replacing an ABS sensor on your Explorer, you don't have to buy the expensive OEM part from the dealer. Quality aftermarket brands offer a reliable and affordable alternative. However, not all aftermarket parts are created equal, especially for critical safety sensors.
Pro Tip: For electronic parts like ABS sensors, it's often worth spending a few extra dollars on a reputable brand to avoid premature failure and diagnostic headaches. Some ultra-cheap, no-name sensors can be dead on arrival or fail within a year.
Brand Quality Tiers
- OEM (Motorcraft): This is the original part your Explorer came with. It guarantees perfect fit and function but comes at the highest price. It's the benchmark for quality.
- Premium Aftermarket (Delphi, Standard Ignition): These brands are well-respected in the industry and often manufacture original parts for various carmakers. They are known for reliable electronics and are a trusted choice for a balance of quality and price.
- Standard Aftermarket (Holstein, Walker Products): These brands provide a cost-effective solution. They are a good option for budget-conscious repairs, though long-term durability may vary compared to premium brands.
Replacement Cost for a 2012-2023 Ford Explorer

| Total (Shop Repair) | $172 - $230 |
Frequently Asked Questions (FAQ)
Can I replace just one ABS sensor?
Yes. You only need to replace the specific sensor that has failed. A diagnostic scan tool can read the trouble codes to tell you which wheel is reporting the fault (e.g., "Left Front Wheel Speed Sensor Circuit Failure").
Is it hard to replace an Explorer ABS sensor myself?
No, it's a DIY-friendly job for most home mechanics. The process involves removing the wheel, locating the sensor on the wheel hub/knuckle, undoing a single bolt, and tracing the wire to its electrical connector to unplug it. The most difficult part can be removing the old sensor if it's seized in the hub due to rust. Gently wiggling and using rust penetrant can help.
Do I need to reset the computer after replacing the sensor?
Once the new sensor is installed, the ABS warning light should turn off on its own after driving a short distance. However, it's always a good practice to use a scan tool to clear the fault codes from the ABS module's memory.
Are the front and rear sensors the same?
No, the front and rear sensors are typically different parts with different wire lengths and mounting designs. You must order the correct sensor for the specific wheel location (e.g., Front Right, Rear Left).
Are there any recalls for the ABS system on the 2012-2023 Explorer?
Searches found recalls for the 2020-2022 Explorer related to a rear axle bolt that could fracture, potentially causing a rollaway condition. The fix involved a software update to the powertrain control module. There were also some Technical Service Bulletins (TSBs) for ABS warning lights on certain 2020-2021 models related to the electric brake booster or specific fault codes, but no widespread recall for the sensors themselves.

The ABS wheel speed sensor for the 2012-2023 Ford Explorer is a two-wire magnetic Hall-effect sensor. It is secured to the wheel knuckle or bearing housing by a single bolt (typically 8mm or 10mm). The sensor wiring harness is routed along the suspension and frame, secured by several clips, and connects to the main vehicle harness in the wheel well or engine bay. Front and rear sensors are not interchangeable.
