Wheel Speed Sensor: Testing and Inspection
FRONT ABS WHEEL-SPEED SENSOR INSPECTIONClearance Inspection
1. Inspect the clearance between the wheel-speed sensor and the sensor rotor.
^ If not as specified, replace the ABS wheel speed sensor or sensor rotor as necessary.
Clearance
Front: 0.2 - 1.1 mm (0.011 - 0.043 inch)
Rear: 0.13 - 1.07 mm (0.006 - 0.042 inch)
Resistance Inspection
1. Disconnect the ABS wheel-speed sensor connector.
2. Inspect resistance at the ABS wheel-speed sensor.
^ If not as specified, replace ABS wheel-speed sensor.
Resistance 1.2 - 1.6 kilohm
Voltage Inspection
1. On level ground, jack up the vehicle and support it evenly on safety stands.
2. Disconnect the wheel-speed sensor connector.
3. Inspect each wheel by rotating it at one revolution per second.
^ If not as specified, replace the ABS wheel-speed sensor or sensor rotor as necessary.
Voltage 0.25 - 3.0 V (AC)
