Why ABS Sensors Are Critical for Your FORTHING M4
The ABS (Anti-lock Braking System) sensor is one of the most vital components in your vehicle’s braking safety technology. It detects wheel speed and sends signals to the ECU to prevent wheel lock-up during emergency braking.
If your ABS sensor fails, your M4 might still brake, but you’ll lose anti-lock capability, increasing the risk of sliding, especially on wet or icy roads.
How to Know It’s Time for a FORTHING M4 ABS Sensor Replacement
Failing ABS sensors aren’t always obvious at first—but ignoring them can compromise your safety.
Warning Signs Include:
-
ABS warning light on dashboard
-
Pulsating brake pedal under normal braking
-
Inconsistent braking on wet surfaces
-
Diagnostic trouble codes (DTCs) showing via OBD-II
If any of these signs appear, it’s time to inspect and potentially replace your FORTHING M4 ABS sensor.
Why Choose OEM ABS Sensors for the M4?
Using a genuine FORTHING OEM sensor guarantees compatibility, longevity, and proper communication with your vehicle’s ECU.
| Feature | OEM ABS Sensor | Aftermarket Alternatives |
|---|---|---|
| Fitment | Engineered for FORTHING M4 | Universal or approximate fit |
| Material Quality | Corrosion-resistant housing | Often lacks long-term protection |
| Signal Accuracy | True wheel speed calibration | May cause ECU miscommunication |
| Longevity | 80,000+ km lifespan | Less predictable durability |
Purchasing from FORTHINGPARTS ensures you receive factory-tested components that won’t trigger false alarms or create electrical noise.

FAQs – FORTHING M4 ABS Sensor Replacement
Can I replace only one ABS sensor or do I need to replace all four?
You can replace only the faulty one, but it’s best to replace both sensors on the same axle for balanced performance.
What happens if I ignore a faulty ABS sensor?
The anti-lock braking system will be disabled, increasing the risk of wheel lock-up in emergencies.
How do I verify which ABS sensor is bad?
Use an OBD-II scanner to read ABS codes or consult a professional diagnostic service.
Do I need to reset the system after replacement?
Not always, but some models may require clearing the ABS fault code via a scan tool.
