Shop direct-fit ABS speed sensors for cars, trucks, and SUVs. Also called ABS wheel speed sensors or wheel speed sensors, these components send wheel-rotation data to the anti-lock braking, traction control, and stability control systems. Choose from front, rear, driver-side, passenger-side, single-sensor, and multi-piece options. Enter your vehicle’s year, make, and model, then confirm the installation position and OE reference number before ordering.
Find the Right ABS Wheel Speed Sensor for Your Vehicle
An ABS warning light does not automatically mean every wheel speed sensor needs replacement. The safest buying process starts by identifying which wheel has an incorrect or missing speed signal and checking the sensor wiring, connector, mounting area, and tone ring for damage or corrosion.
Once the failed location is confirmed, enter your vehicle’s year, make, and model to narrow the results. Before ordering, compare the product information with the original part and verify:
- Front or rear installation
- Driver or passenger side
- Single sensor, axle pair, or front-and-rear set
- Connector shape and terminal count
- Wire length, routing, and mounting points
- OE or interchangeable part number
- Vehicle notes such as drivetrain, body style, trim, or production date
ABS wheel speed sensors can look similar while using different connectors, wire lengths, mounting brackets, or signal types. Matching only the vehicle model—or only the sensor’s appearance—can result in ordering the wrong part.
What Does an ABS Speed Sensor Do?
The ABS speed sensor monitors the rotation of an individual wheel and sends that information to the ABS control module. When the module detects that one wheel is slowing more rapidly than the others, it can adjust brake pressure to help prevent wheel lockup.
Wheel-speed information may also be used by the traction control and electronic stability control systems. This is why one damaged sensor, connector, or sensor circuit can illuminate several warning lights at the same time. Learn more about what an ABS sensor does and what causes it to fail.
Depending on the vehicle, the sensor may be mounted near the wheel hub, steering knuckle, axle, or differential. On some applications it is integrated into the wheel hub bearing assembly, so check the vehicle-specific configuration before purchasing a separate sensor.
Common Signs of a Bad ABS Wheel Speed Sensor
A failing ABS wheel speed sensor or damaged sensor circuit may cause:
- ABS, traction control, or stability control warning lights
- ABS activation during a normal low-speed stop
- Loss of ABS or traction-control assistance
- Inconsistent wheel-speed data on a capable scan tool
- Speedometer or cruise-control problems on certain vehicles
See the complete guide to faulty ABS wheel speed sensor symptoms for more detail. These symptoms can also result from damaged wiring, connector corrosion, debris at the sensor mounting surface, a cracked or rusted tone ring, excessive wheel-bearing play, or an ABS module fault.
Scan the ABS system and inspect the related components before replacing a sensor. If contamination is present, first determine whether the dirty ABS sensor can be cleaned or should be replaced.
Front vs. Rear ABS Sensors: Does Position Matter?
Yes. Front and rear ABS sensors are frequently different, and many vehicles also use separate driver-side and passenger-side designs. The mounting tab, connector orientation, wire routing, sensor length, and electrical specifications must match the required wheel position.
Do not assume that a front sensor fits both front wheels unless the listing specifically states “front driver or passenger.” Likewise, a listing marked “rear driver” should not be ordered for the rear passenger side.
If several sensors are available for the same vehicle, use the original sensor number or the OE interchange information in the product listing to confirm the correct configuration.
Should You Replace One ABS Sensor or a Set?
A vehicle does not normally require all four ABS sensors to be replaced because one sensor fails. If diagnosis identifies one damaged sensor and the other sensors produce stable signals, replacing the affected unit is usually sufficient. Read the detailed guide to understand when ABS sensors should be replaced individually or as a set.
A two-piece or four-piece set may make sense when multiple sensors are damaged, wiring has deteriorated at several wheels, or the vehicle is already undergoing broader hub or suspension work. Compare the installation positions included in the set before ordering; “front and rear” does not always mean the kit fits every configuration of that model.
Why Choose A-Premium ABS Speed Sensors?
A-Premium offers vehicle-specific ABS speed sensors for a wide range of domestic, Asian, and European cars, trucks, and SUVs. Available options include single front or rear sensors, driver- and passenger-side units, axle pairs, and complete front-and-rear sets.
Each listing provides vehicle fitment, installation position, quantity, and available OE interchange information to help reduce wrong-part orders. Direct-fit designs are intended to match the original mounting and connector configuration without unnecessary modification.
As a brand-direct supplier, A-Premium reduces added distribution markups while offering practical replacement options at competitive prices. Eligible ABS speed sensors include a three-year warranty and 90-day free returns; check the individual product listing and policy terms for coverage.
If you are unsure which sensor fits, contact customer service with your vehicle information and original part number before ordering. Once fitment is confirmed, use the vehicle service procedure or consult this ABS sensor replacement guide before beginning installation.
Frequently Asked Questions (FAQ)
Is an ABS sensor the same as a wheel speed sensor?
In this category, the terms ABS sensor, ABS speed sensor, ABS wheel sensor, and ABS wheel speed sensor usually refer to the sensor that monitors wheel rotation for the anti-lock braking system. A vehicle may contain other speed sensors for the engine or transmission, so confirm the sensor location and function before purchasing.
How do I know which ABS sensor is bad?
Use a scan tool capable of communicating with the ABS module and compare live wheel-speed data when possible. Also inspect the wiring, connector, mounting surface, tone ring, and wheel bearing at the affected position. A fault code identifies the circuit or wheel requiring investigation but does not always prove that the sensor itself has failed.
Can I drive with a bad ABS speed sensor?
The vehicle’s conventional hydraulic brakes may still operate, but ABS, traction control, or stability control assistance may be limited or disabled. Braking behavior can be less predictable on wet, icy, or loose surfaces. Have the fault diagnosed promptly, and stop driving if braking performance feels abnormal.
Will the ABS warning light turn off after sensor replacement?
It depends on the vehicle and the type of fault. Some systems turn the light off after receiving a valid wheel-speed signal during a drive cycle, while others require the stored code to be cleared with a compatible scan tool. If the light remains on, recheck the connector, wiring, fitment, mounting gap, tone ring, and diagnostic codes.
