Volkswagen 3-Pin Waterproof Traction Control Sensor Connector – Female OEM

This 3-pin waterproof female connector is used in Volkswagen traction control and ABS sensor harnesses. The 3-pin configuration serves wheel speed sensor or traction control sensor circuits on VW PQ and MQB platform vehicles. Available bare or with 15cm pre-wired leads.

Key Specifications

Why Traction Sensor Connectors Fail

Traction control and ABS sensor connectors on VW vehicles are mounted near the wheel hub, exposed to road spray, mud, salt, and constant vibration. Terminal corrosion or housing damage causes ABS sensor open-circuit faults, traction control deactivation, and C-code fault codes. Replacing the connector restores clean sensor signal continuity and clears ABS/ESC faults.

Variant Guide

• Female – Bare 3-pin housing with terminals
• Female 15CM – Pre-wired with 15cm leads for direct splice-in installation

Installation Steps

1. Safely lift and support the vehicle; remove the wheel if necessary
2. Locate the 3-pin traction/ABS sensor connector near the hub/knuckle
3. Disconnect the original connector and inspect terminals for corrosion
4. Transfer terminals to the new housing or splice in the pre-wired variant
5. Route and secure the harness away from moving parts
6. Clear ABS/ESC fault codes with VCDS or OBD11

Frequently Asked Questions

Q: What VW models use this 3-pin traction sensor connector?
A: This connector is used on VW Golf, Passat, Tiguan, Polo, and Touareg ABS/traction control harnesses on PQ and MQB platforms. Cross-reference your vehicle’s wiring diagram to confirm fitment.
