Saab ABS Speed Sensor

Restore your vehicle's anti lock braking system and safety features with a high-performance ABS speed sensor. Whether you are dealing with an abs system failure or a flickering abs warning lamp, our sensors provide the wheel speed data necessary to maintain steering control and traction during heavy braking.

What Does an ABS Sensor Do?

An ABS sensor (also known as an abs speed sensor or abs wheel sensor) is a critical component of your vehicle’s anti lock braking system. Its primary function is to monitor the wheel speed of each individual tire and transmit real-time wheel speed data to the abs module.

By sending a constant signal, the sensor allows the abs computer to modulate brake pressure during heavy braking. This prevents the wheels from locking up, ensuring the traction control system and electronic stability programs function properly. This process is vital to maintain steering control and reduce stopping distances, keeping your car safe on every road surface.

Two Industry-Leading Technologies

A-Premium provides both passive and active technology to match your vehicle's specific brake system requirements:

• Magnetic-Electric Sensors (Passive): Uses a magnetic circuit and coil to create an output voltage. While cost-effective for rear wheel drive applications or rear differential mounts, they may produce a low voltage output at very low speeds.

• Hall Effect Sensor (Active): The modern standard. It generates a precise pulse width and output wave form that the control module can read even at 0 mph. These are highly resistant to vibration and harsh elements.

Symptoms of a Faulty ABS Sensor

When a wheel speed sensor fails, the abs system loses its ability to determine accurate rotation data. This abs system failure often triggers an abs light or abs warning lamp on the dashboard. Without a functional abs speed sensor, your vehicle’s safety network—including stability control and emergency braking—is compromised.

The 4 Most Common Signs of a Failing Sensor:

1. Dashboard Warnings: An active abs warning lamp or traction light indicates the control module has detected a system error.

2. The "Pulsing" Brake Pedal: You may feel the brake pedal grind or pulse during slow, normal stops. This happens because a failing sensor sends incorrect data, leading the abs computer to falsely believe a wheel is locking up.

3. Erratic Speedometer: If the abs speed sensor provides the primary speed signal, a failure will cause the speedometer to drop to zero.

4. False ABS Activation: An inadequate quality inspection on inferior parts can lead to the abs engaging on dry pavement.

Pro Tip: Before replacement, check the sensor tip for brake dust, metallic debris, or iron filings. A dirty sensor tip hitting a gap in the target wheel can mimic a faulty abs sensor. Clean the sensor with a microfiber cloth and check the water tight connection for corrosion.

How ABS Sensors Work with Other Systems

The ABS sensor is a cornerstone of your vehicle’s integrated safety network. Because the abs module relies on accurate wheel speed data to determine how to modulate brake pressure, a single faulty abs sensor can impact multiple systems beyond just the brakes.

When replacing your wheel speed sensor, we recommend inspecting these related components:

• Brake Pads & Rotors: Worn brake pads or warped rotors can create excessive vibration, which may interfere with the sensor's ability to read the target wheel correctly.

• Wheel Hub Assembly: On many modern vehicles, the abs wheel sensor is integrated directly into the hub. If the internal bearings fail, they can cause the sensor tip to misalign, resulting in a distorted output wave form.

• Traction Control System: This system relies entirely on abs data to prevent wheel spin. If the signal is lost, traction management will be disabled to operate safely.

• ECU / ABS Module: The control module processes millisecond-perfect data to maintain steering control during heavy braking. Ensure the oe connectors are free of corrosion to maintain this vital link.

Regularly monitoring your abs speed sensor can prevent sudden abs system failure and ensure your anti lock braking system is always ready for emergency maneuvers.

Frequently Asked Questions

Why do front ABS sensors fail more often than rear sensors?

The front sensor works in a much harsher environment (debris, heat, motion) than the rear, so it naturally wears out faster.

How do I know which ABS sensor needs repair or replacement?

Connect the scanner to the vehicle’s OBD port. It will tell you exactly which wheel sensor is faulty (e.g., "Left rear wheel speed sensor signal error" or "Right front sensor circuit problem").

Can I drive with a bad ABS sensor?

Yes, but ABS functionality will be disabled, reducing braking safety—especially in emergency situations.

Do I need to check the sensor tip during installation?

Absolutely. You must ensure proper mounting so that the sensor tip is at the correct distance from the target wheel. If it is too close, you risk the sensor tip hitting the ring; too far, and the signal will be too weak.

Can I replace just one abs speed sensor?

While you can replace one, we recommend pairs. If one sensor has succumbed to road surface grime and vibration, the other wheel sensor on the same axle is likely near failure.

Do I need to reset the dashboard light after installation?

In most vehicles, the ABS light will turn off automatically after driving a short distance (usually above 15-20 mph) once the new sensor sends a valid signal. If not, an OBD-II scanner can be used to clear the history codes.
