Wheel Sensor Output
- Raise vehicle and support. Place wheel sensor selector switch to "O/P" position. Turn wheel sensor switch to "Front L". Rotate wheel by hand, so wheel spins more than one revolution per second. If wheel sensor light comes on, go to next test.
- If LED light does not come on, check wheel sensor air gap. See WHEEL SENSOR under REMOVAL & INSTALLATION in this article. Check for loose or damaged wheel sensor, sensor ring or wheel bearings. Repair as necessary and retest. Test each wheel sensor using this method. Ensure wheel sensor switch is at proper position.
