WABCO ABS Sensor Replacements
Reliable Parts. Expert Support. Fast Shipping.
Your ABS system isn’t just a regulatory requirement —it’s a critical piece of safety technology.
Whether you’re managing a fleet or repairing a single truck, keeping your ABS sensors in top condition is non-negotiable. And when it comes to performance and durability, WABCO ABS sensor replacements are the gold standard in the heavy-duty vehicle world.
At Precision Transmission, we stock and ship genuine WABCO ABS sensor replacements designed to fit a wide range of trucks, trailers, and specialty vehicles. Our parts are 100% OEM-certified, backed by technical expertise, and available for fast delivery or local pickup.
What Is a WABCO ABS Sensor?
An ABS sensor—also called a wheel speed sensor—is a small but powerful device located near the wheel hub. It measures wheel rotation speed and sends that data to the vehicle’s ABS control module.
When a potential lock-up is detected, the ABS system modulates brake pressure in milliseconds, preventing skidding and maintaining steering control.
WABCO ABS sensor replacements are designed to match factory specs for both analog and digital sensor systems and ensure consistent signal transmission in harsh environments.
Common Signs of a Faulty ABS Sensor
ABS sensors wear out or fail due to moisture, corrosion, heat damage, or everyday wear and tear.
Here are a few signs that it may be time for a WABCO ABS sensor replacement:
- ABS light on the dash
- Intermittent or total loss of ABS function
- Diagnostic fault codes (MID 136, SID 4, etc.)
- Irregular braking behavior
- Trailer brake lock-up during low-speed stops
- Visible sensor damage or wire corrosion
Many fleet managers and mechanics make the mistake of chasing down relay valves or modulators—when the issue is often a simple sensor swap. Start small, and replace what’s most likely

Troubleshooting ABS Sensor Issues
Even with a fresh sensor installed,
ABS issues can still persist if related systems are damaged or contaminated. Here’s how to narrow it down:
Common Warning Signs:
- Check the tone ring. Missing or damaged teeth will confuse the signal.
- Test wiring resistance. A good WABCO ABS sensor should read around 1,000 to 1, 300 ohms (passive).
- Use WABCO TOOLBOX software. It provides real-time data from ABS and EBS systems.
- Look for water ingress. Moisture in the connectors or cable sheath can cause voltage drop

WABCO ABS Sensor FAQs
No. Even within the WABCO family, sensorspecs (length, connector type, signal type) vary byapplication. Always check compatibility.
If undamaged, yes. But we recommend replacing it if there’s any corrosion or distortion.
Most systems self-calibrate, but newer vehicles or those using EBS may require a diagnostic reset.
Yes. Passive sensors can be tested with a multimeter for resistance and AC voltage signal when rotated. Active sensors may require a diagnostic tool
