3) Check the clearance of the sensor. <Ref. to
ABS-14, SENSOR GAP, INSPECTION, Front ABS
Wheel Speed Sensor.>
If clearance is out of the standard value, readjust by
using spacer (Part No. 26755AA000).
ABS wheel speed sensor gap standard value:
0.3 — 0.8 mm (0.012 — 0.031 in)
Tightening torque:
33 N·m (3.3 kgf-m, 24 ft-lb)
NOTE:
• Check the identification (mark) on the harness to
make sure there is no warpage. (RH: Yellow green,
LH: Pink)
• Check if the harness is not pulled and does not
come in contact with the suspension or body during
steering wheel effort.
4) After confirmation of the ABS wheel speed sen-
sor clearance, connect the connector to the ABS
wheel speed sensor.
5) Connect the ground cable to the battery.
C: INSPECTION
1. ABS WHEEL SPEED SENSOR
1) Check the pole piece of the ABS wheel speed
sensor for foreign particles or damage. If neces-
sary, clean the pole piece or replace the ABS wheel
speed sensor.
2) Measure the ABS wheel speed sensor resis-
tance.
If resistance is out of the standard value, replace
with a new ABS wheel speed sensor.

NOTE:
Check the ABS wheel speed sensor cable for dis-
continuity. If necessary, replace with a new part.
2. SENSOR GAP
1) Measure the distance "A" between the ABS
wheel speed sensor surface and sensor pole face.
A
2) Measure the distance "B" between the surface
where the front axle housing meets the ABS wheel
speed sensor, and the tone wheel.
NOTE:
Measure so that the gauge touches the apex of the
tone wheel teeth.
B
(1) Axle housing
(2) Tone wheel
3) Find the gap between the ABS wheel speed sen-
sor pole face and the surface of the tone wheel
teeth by entering and calculating the measured val-
ues in the formula below.
ABS wheel speed sensor gap = B – A
ABS wheel speed sensor gap standard value:
0.3 — 0.8 mm (0.012 — 0.031 in)
NOTE:
If clearance is out of the standard value, readjust by
using spacer (Part No. 26755AA000).
