3) Check the ABS wheel speed sensor gap. <Ref.
to ABS-14, SENSOR GAP, INSPECTION, Front
ABS Wheel Speed Sensor.> After standard clear-
ance is obtained, tighten the ABS wheel speed
sensor on housing to specified torque.
If the clearance is outside specification, readjust
using spacer (Part No. 26755AA000).
ABS wheel speed sensor standard clearance:
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 marks on the harness and make sure
that no kink exists. (RH: White, LH: Yellow)
• Make sure the harness is not pulled and does not
contact to suspension or body when steering wheel
is turned.
4) After confirmation of the ABS wheel speed sen-
sor clearance, connect the connector to ABS wheel
speed sensor.
5) Connect the battery ground cable to battery.

C: INSPECTION
1. ABS WHEEL SPEED SENSOR
1) Check the pole piece of ABS wheel speed sen-
sor for foreign particles or damage. If necessary,
clean the pole piece or replace ABS wheel speed
sensor.
2) Measure the ABS wheel speed sensor resis-
tance.
If the resistance is outside standard value, replace
the ABS wheel speed sensor with a new one.
Terminal No.
1 and 2
NOTE:
Check the ABS wheel speed sensor cable for dis-
continuity. If necessary, replace with a new one.
2. SENSOR GAP
1) Measure the distance "A" between ABS wheel
speed sensor surface and sensor pole face.
