Wheel Speed Sensor Inspection

WARNING: This page is about a different car, the 2009 Honda S2000, 2008 Honda S2000, 2007 Honda S2000, and 2006 Honda S2000. However, it is still accessible from the selected car via links, so may be relevant.

Inspect the front and rear pulsers for chipped or damaged teeth.
Measure the air gap between the wheel speed sensor and pulser all the way around while rotating the pulser. Remove the rear brake disc to measure the gap on the rear wheel speed sensor. If the gap exceeds 1.0 mm (0.04 in.), check for a bent suspension arm.

Standard:

Front/Rear: 0.4-1.0 mm (0.02-0.04 in.)
