TRW Automotive AfterMarket GBS1087 ABS Sensor
The TRW GBS1087 ABS sensor is a high‑performance wheel speed detector designed to deliver precise and reliable data for the Anti‑Lock Braking System (ABS) and Electronic Stability Program (ESP). Engineered by TRW Automotive, this active sensor integrates advanced magnetic sensing technology with robust construction to withstand harsh automotive environments.
Core Functionality
The primary role of the GBS1087 is to monitor wheel rotation speed and transmit accurate frequency signals to the vehicle’s control module. By continuously measuring wheel velocity, the sensor enables:
- ABS operation: Prevents wheel lock‑up during emergency braking.
- ESP/Traction Control: Detects loss of traction and applies selective braking.
- Vehicle stability monitoring: Provides data for yaw, lateral acceleration, and steering angle integration.

Compatibility and Vehicle Support
The GBS1087 is specifically engineered for the Peugeot 307 family, including:
- 307 3‑door hatchback (3A/C)
- 307 SW estate (3H)
- 307 Break/Station Wagon (various engine configurations: 1.4‑2.0 L, HDi, 16V)
It is also suitable for other vehicles that share the same wheel hub geometry and ABS architecture as the Peugeot 307 series.
Installation Guide
- Preparation: Ensure the vehicle’s battery is disconnected. Remove the wheel and brake caliper to access the wheel hub assembly.
- Remove Old Sensor: Detach the existing sensor by unscrewing the mounting bolts. Carefully disconnect the electrical connector, noting the polarity.
- Install New Sensor: Position the GBS1087 onto the hub, aligning the magnetic pole with the wheel’s iron ring. Secure with the provided bolts and torque to manufacturer specifications.
- Reconnect Wiring: Plug the sensor connector into the vehicle’s harness, ensuring a snug fit.
- Reassemble Components: Reinstall the brake caliper, wheel, and tire. Tighten all fasteners in the correct sequence to avoid cross‑torque issues.
- System Check: Reconnect the battery, start the engine, and verify that the ABS light remains off or turns on briefly during a test drive. Use an OBD‑II scanner to confirm sensor data integrity.
Benefits of Choosing TRW GBS1087
- High Accuracy: Precision magnetic sensing delivers reliable wheel speed readings even under extreme braking conditions.
- Durability: Rugged housing and sealed bearings protect against dust, moisture, and vibration.
- Low Power Consumption: Optimized for efficient operation within the vehicle’s electrical system.
- Easy Replacement: Standard mounting interface allows quick swap with minimal tools.
- Certified Safety: Meets ISO 26262 requirements, ensuring functional safety in critical braking scenarios.
Troubleshooting Common Issues
| Symptom | Possible Cause | Recommended Action |
|---|---|---|
| ABS warning light stays on after replacement | Incorrect sensor polarity or loose connection | Check connector orientation and secure all terminals. |
| Erratic brake pedal feel | Sensor misalignment with wheel hub | Re‑align the sensor, ensuring magnetic pole contacts the iron ring properly. |
| No data from OBD‑II scanner | Faulty wiring or damaged sensor | Inspect wiring harness for breaks; replace sensor if necessary. |
| Sensor overheating during long drives | Excessive ambient temperature or inadequate ventilation | Verify that the vehicle’s cooling system is functioning and that no obstructions block airflow around the hub. |
Maintenance Tips
- Periodically inspect the sensor connector for corrosion; clean with a non‑abrasive brush if needed.
- Avoid using metal tools that could damage the sensor housing or magnetic pole.
- When replacing tires, ensure the wheel hub is free of debris before installing the new sensor.
Why TRW Remains a Trusted Name
TRW Automotive has a long history of supplying high‑quality automotive components worldwide. The GBS1087 embodies this legacy through:
- Rigorous testing under simulated crash and braking scenarios.
- Adherence to global safety standards, including ISO 26262 and UNECE regulations.
- Continuous improvement driven by customer feedback and field data analytics.
Conclusion
The TRW GBS1087 ABS sensor delivers unmatched reliability for the Peugeot 307 series, ensuring that braking performance remains safe and consistent. Its robust construction, precise sensing capability, and straightforward installation make it an ideal choice for both professional technicians and knowledgeable DIY enthusiasts seeking to maintain or upgrade their vehicle’s safety systems.
