Wheel Sensor Inspection

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2004 Honda Odyssey, 2003 Honda Odyssey, 2002 Honda Odyssey, 2001 Honda Odyssey, and 2000 Honda Odyssey. 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 sensor and pulser all the way around while rotating the pulser. Remove the rear brake disc to measure the gap on the rear wheel sensor. If the gap exceeds 1.0 mm (0.04 in.), check for a bent suspension arm.
Standard:
1. Front: 0.5-1.0 mm (0.02-0.04 in.)
2. Rear: 0.2-1.1 mm (0.01-0.04 in.)
