WHEEL SENSORS
Removal and InstallationINFOID:0000000001327698
REMOVAL
1. Disconnect wheel sensor connector.
2. Remove wheel sensor mounting bolts, grommets (front sensor) and clip.
3. Remove wheel sensor.
CAUTION:
Be careful of the followin
g when installing sensor.
 As much as possible, avoid rotati ng sensor when removing it. Pull sensors out without pulling on
sensor harness.
 Take care to avoid damaging sensor edges or roto r teeth. Remove wheel sensor first before remov-
ing front wheel hub and bearing assembly and rear fina l drive. This is to avoid damage to sensor wir-
ing and loss of sensor function.
INSTALLATION
Note the following, and install in the reverse order of removal.
CAUTION:
Be careful of the follow ing when installing sensor. Tighten in stallation bolts to specified torques.
 When installing, make sure there is no foreign material such as iron chips on pick-up and mounting
hole of sensor. Make sure no foreign material h as been caught in the sensor rotor. Remove any for-
eign material and clean the mount.
 When installing front sensor, be sure to press rubber grommets in until they lock at the three loca-
tions shown in the figure (2 at shock absorbers and 1 at body pa nel). When installed, harness must
not be twisted. White line on ha rness must be visible from front.
 When installing rear sensor, attach harness at rear suspension member securely. Besides, harness
must not be twisted when installed.
