What This Product Does:

• Restores ABS Functionality – Ensures the ABS system receives accurate wheel speed signals.
  
• Maintains Traction Control & Stability Systems – Many Porsche safety systems rely on proper ABS sensor signals.
  
• Corrects Electrical Faults – Replaces damaged or corroded wiring/connectors in the sensor harness.
  
• Cost-Effective Solution – Allows repair without replacing the full wiring loom.
  
  

Symptoms Of A Faulty ABS Sensor Harness:

• ABS warning light illuminated on the dashboard.
  
• Traction control / PSM (Porsche Stability Management) light turning on.
  
• Inconsistent or false ABS activation (brakes pulsing when they shouldn’t).
  
• Loss of ABS or traction control functions under braking or acceleration.
  
• Fault codes stored for front left ABS/speed sensor in diagnostics.
  
• Physical damage such as cracked insulation, frayed wiring, or corroded connectors.
  
  

Why Replacement Matters: 
The ABS system is critical for safe braking performance. If the harness is faulty, the system may become disabled, putting safety at risk. This repair kit restores proper connection between the ABS sensor and control module, ensuring reliable operation of ABS, traction control, and stability systems.

One of the most common problems ABS/PASM light coming on and it says it is the right front sensor with a reading out of range. If you switched the left front and right front sensors and still getting the same fault code. Next course of action is going to be to replace the wiring going to the sensor since assuming there is a break in the wires or a short.

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.
