TRW Automotive AfterMarket GBS1114 ABS Sensor

TRW Automotive AfterMarket GBS1114 ABS Sensor

The TRW GBS1114 is a high‑performance ABS wheel speed sensor designed to deliver reliable braking performance and precise electronic stability control (ESC) data for a wide range of rear‑wheel vehicles. Manufactured by TRW, a leader in automotive safety components, this sensor integrates advanced magnetic sensing technology with robust mechanical construction to withstand harsh operating environments.

Key Functionalities

The GBS1114 operates as an active wheel speed sensor, generating a high‑frequency signal proportional to the rotational speed of each rear wheel. This signal is fed directly into the vehicle’s ABS/ESC control unit, enabling:

• Accurate wheel slip detection during braking or acceleration.
• Real‑time stability monitoring for cornering and traction control.
Seamless integration with the vehicle’s electronic brakeforce distribution (EBD) system.

Design & Construction

The sensor features a compact, lightweight housing that protects internal components from dust, moisture, and vibration. Its magnetic encoder ring is engineered for high‑resolution speed measurement, while the integrated temperature compensation circuit ensures consistent performance across a wide temperature range.

Compatibility & Vehicle Support

The GBS1114 is specifically calibrated for rear‑wheel applications in several popular models. It is fully compatible with:

• CITROËN C6 – including sedan, coupe, and hatchback variants.
• PEUGEOT 407, 407 SW, and 407 Coupe – across the 1.6D‑3.0L engine range.
• Other vehicles that share the same rear wheel speed sensor architecture, such as certain Peugeot C6 models.

For each supported vehicle, the GBS1114 is available in both left and right rear positions, ensuring a complete replacement set for optimal braking symmetry.

Installation & Maintenance

Installing the TRW GBS1114 involves removing the existing wheel speed sensor from the rear axle housing. The new sensor aligns with the same mounting points and electrical connectors, allowing a straightforward swap without additional adapters. Key installation steps include:

1. Disconnect the battery to prevent accidental electrical discharge.
2. Remove the wheel cover and access the sensor housing.
3. Detach the old sensor, noting the orientation of the magnetic ring.
4. Install the GBS1114, ensuring proper alignment with the axle shaft.
5. Reconnect the electrical connector and secure the housing.
6. Re‑connect the battery and perform a diagnostic check to confirm sensor functionality.

Routine maintenance is minimal; however, inspecting the sensor for physical damage or corrosion after severe weather conditions can preempt potential failures.

Performance Benefits

• Enhanced braking stability through precise wheel speed data.
• Improved traction control by providing accurate slip detection during acceleration.
• Long‑lasting durability thanks to TRW’s proven manufacturing standards.
• Reduced risk of ABS/ESC malfunctions, leading to safer driving experiences.
