WHEEL SENSORS

PFP:47910

Removal and Installation

NFS000H8

REMOVAL

Be careful of the following.

CAUTION:

●

As much as possible, avoid rotating wheel sensor when removing it. Pull wheel sensors out with-
out pulling on sensor harness.

●

Take care to avoid damaging wheel sensor edges or rotor teeth. Remove wheel sensor first before
removing front or rear wheel hub. This is to avoid damage to wheel sensor wiring and loss of sen-
sor function.

INSTALLATION

Be careful of the following. Tighten the mounting bolts and nuts to the specified torque. Refer to 

BRC-97,

"Removal and Installation"

 .

●

When installing, make sure there is no foreign material such as iron chips on and in the mounting hole of
the wheel sensor. Make sure no foreign material has been caught in the sensor rotor. Remove any foreign
material and clean the mount.

●

When installing wheel sensor, be sure to press rubber grommets in until they lock at locations shown
above in figure. When installed, harness must not be twisted.
