Removing and installing front speed sensors: Installation
NOTE:
- Before installation, ensure that there are no metal chips at the magnetic edge of the speed sensor!
- The gap between speed sensor and pulse wheel is determined by the design and cannot be adjusted!
- There is no O-ring between speed sensor and wheel carrier!
- The speed sensors at front and rear axles are the same! This applies to version -A- and version -B- .
- Coat speed sensor and the bore in the wheel carrier with Molykote Longterm 2.
- Without using excessive force, insert speed sensor into wheel carrier and tighten the hexagon socket head bolt to 10 N.m (7.5 ftlb.).
- If the speed sensor was removed or replaced due to a fault with the ABS, Traction Control or PSM or due to accident repairs, a functional check should be carried out. This is done with the Porsche System Tester 2, via the Actual values menu item, submenu Speed.
