Speed ABS / Sensor Harness Repair Kit, REAR.
Restore your Porsche’s braking and stability systems with these rear ABS / speed sensor harness repair kits. Designed for direct repair of the rear left and rear right sensor wiring, these kits replace worn or damaged harnesses that can trigger ABS and traction control faults.
Over time, ABS wiring can suffer from corrosion, cracks, or connector wear, leading to dashboard warning lights and reduced braking performance. These repair kits provide a cost-effective solution without needing to replace the full wiring loom, ensuring your ABS, traction control, and Porsche Stability Management (PSM) operate as intended.

What This Product Does:

The rear ABS/speed sensor harness repair kit is designed to replace the damaged or faulty wiring that connects the rear wheel speed sensors to the ABS control module.

Functions Include:

• Restoring ABS accuracy – Transmits precise wheel speed data from the rear wheels.
  
• Maintaining Traction Control & PSM (Porsche Stability Management) – Critical for stability and braking systems.
  
• Repairing Faulty Wiring/Connectors – Fixes issues caused by wear, corrosion, or damage.
  
• Cost-Efficient Solution – Replaces only the defective section of harness instead of the entire loom.
  
  

Symptoms Of A Failing Rear ABS Sensor Harness:

• ABS warning light illuminated on the dashboard.
  
• Traction control / PSM light on or flashing.
  
• Inconsistent ABS operation – pulsing brakes when unnecessary or ABS not engaging when it should.
  
• Loss of stability or traction control under acceleration or cornering.
  
• Stored fault codes for rear left or rear right ABS/speed sensor.
  
• Physical damage – cracked insulation, frayed wiring, or corroded connectors at the sensor.
  
  

Why Replacement Matters:
The ABS and traction control systems are safety-critical. A failed harness can disable these systems, leading to longer stopping distances and reduced control in poor conditions. Installing a new repair kit restores reliable communication between the rear wheel sensors and the ABS control unit.
