Reference
When using oscilloscope for this check, check if peak-to-peak
voltage (1) meets specification and waveform is complete.
Peak-to-peak voltage at 1 to 1 1/3 rotation per second
: 280 mV or more at 43 – 57 Hz
REMOVAL
1) Disconnect negative cable at battery.
2) Disconnect front wheel speed sensor coupler (1).
3) Hoist vehicle and remove wheel.
4) Remove harness clamp bolts (2) and grommet (3).
5) Remove front wheel speed sensor (4) from knuckle.

• Do not cause damage to surface of front wheel speed
sensor and do not allow dust, etc. to enter its installa-
tion hole.
SENSOR INSPECTION
• Check sensor for damage.
• Check sensor for resistance and continuity.
Between both terminals (1) sensor
: 1.2 – 1.6 kΩ at 20°C (68°F)
Between sensor terminal and sensor body (2)
: No continuity
• If the check result is not as specified and any malfunction is
