Removing and installing front speed sensors: Installation
- Coat speed sensor and the bore in the wheel carrier with Molykote Longterm 2.NOTE: There is no O-ring between speed sensor and wheel carrier. The speed sensors at front and rear axles are the same.
- Without using excessive force, insert speed sensor into wheel carrier and tighten the hexagon socket head bolt to 10 Nm (7.5 ftlb.).
- If the speed sensor has been removed or replaced due to an ABS fault or Traction Control fault, or because of accident repairs, a functional check should be carried out with the Porsche System Tester 2, via the Actual Values menu, Speed.
