Inspection
Check the front and rear pulser for chipped or dam-aged teeth.
Measure the air gap between the wheel sensor andpulser all the way around while rotating the pulser.
Slandard: 0.4 - 1.0 mm (0.02 - 0.04 in,
NOTE; lf the gap exceeds 1.0 mm (0.04 in), theprobability is a distorted suspension arm which
should be replaced.
