CIRCUIT INSPECTION
DTC
C0200 / 31 - C1239 / 39Speed Sensor Circuit
CIRCUIT DESCRIPTION
The speed sensor detects wheel speed and sends the ap-
propriate signals to the ECU. These signals are used for control
of the ABS & BA & TRAC & VSC control system. The front and
rear rotors each have 48 serrations.
When the rotors rotate, the magnetic field emitted by the perma-
nent magnet in the speed sensor generates AC voltage. Since
the frequency of this AC voltage changes in direct proportion to
the speed of the rotor, the frequency is used by the ECU to de-
tect the speed of each wheel.

Detection of any of the conditions 1. through 4.:
1. At a vehicle speed of 6 mph (10 km/h) or more, pulses
are not input for 15 sec.
2. Momentary interruption of the speed sensor signal oc-
curs at least 7 times in the time between switching the
ignition switch ON and switching it OFF.
3. Continuous noise occurs into the speed sensor signals
with a vehicle speed at 12 mph (20 km/h) or more.
4. The condition that the speed sensor signal circuit is
open continues for 0.12 sec. or more.
ABS does not function
Brake pedal is not depressed
Parking brake is not set
Rear differential does not lock
Under the above conditions, when the difference in velocity
between the highest rotating and the second highest rotat-
ing wheels is within 1 mph (2 km/h), the slowest wheel ro-
tates at 0 mph (0 km/h), and the second slowest wheel
rotates at 7 mph (12 km/h) for 1 second or more.
