Front Wheel-Speed Sensor
INSPECTIONRemove the wheel and tire, and inspect the sensor for looseness and damage. Replace the sensor as necessary.
Clearance Inspection
Inspect for clearance between the wheel-speed sensor and the sensor rotor.
Clearance: 1.3 - 2.0 mm (0.0512 - 0.0787 inch)
Resistance Inspection
1. Disconnect the ABS wheel-speed sensor connector.
2. Inspect for resistance at the ABS wheel-speed sensor.
Resistance: 1.28 - 1.92 ohms.
Voltage Inspection
1. On level ground, jack up the vehicle and support it evenly on safety stands.
2. Disconnect the ABS wheel-speed sensor connector.
3. Inspect each wheel by rotating it at one revolution per second.
Voltage: 0.23 volts minimum (AC)
4. If not as specified, replace the ABS wheel-speed sensor.
Voltage Pattern Inspection
1. On level ground, jack up the vehicle and support it evenly on safety stands.
2. Disconnect the ABS wheel-speed sensor connector and connect an oscilloscope to the sensor connector.
3. Inspect for voltage pattern by rotating it at one revolution per second.
