Charts A-7 To A-10: Wheel Sensor Ck
WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 1988 Oldsmobile Ninety-Eight, 1988 Oldsmobile Delta 88, 1987 Oldsmobile Ninety-Eight, 1987 Oldsmobile Delta 88, and 1986 Oldsmobile Ninety-Eight. However, it is still accessible from the selected car via links, so may be relevant.
Wheel sensors, sends a AC signal to EBCM, by passing a toothed ring past 2-pole inductive sensor. EBCM determines calculated wheel speed, using sensor output frequency, to detect wheel lock-up. Voltage can be as low as 50 millivolts. Resistance of sensor should be 800-1400 ohms. If cable is damaged, repair or replace cable, using manufacturer repair kit.
