CAUTION:
- Be careful not to damage wheel sensor edge and sensor rotor
teeth.
- When pulling out the wheel sensor, be careful to turn it as
little as possible. Do not pull on the wheel
sensor harness.
- Check if foreign objects such as iron fragments are adhered to
the pick-up part of the sensor or to
the inside of the hole for the wheel sensor, or if a foreign object is
caught in the surface of the mating
surface for the wheel sensor. Repair as necessary and then install the wheel
sensor.
REMOVAL
- Remove the front wheel and tire using power tools. Refer to WT-60,
"Adjustment".
- Partially remove front wheel fender protector and reposition out
of the way. Refer to EXT-24, "Removal
and Installation".
- Disconnect the harness connector from the front wheel sensor.
- Remove the front wheel sensor harness from the brackets.
- Remove the front wheel sensor bolt and front wheel sensor from the
front wheel hub and bearing assembly.
INSTALLATION

Installation is in the reverse order of removal.
CAUTION:
Do not twist rear wheel sensor harness when installing rear
wheel sensor. Check that grommet (2) is fully inserted to

Removal and Installation - Rear Wheel Sensor
CAUTION:
- Be careful not to damage wheel sensor edge and sensor rotor
teeth.
- When removing the front or rear wheel hub, first remove the
wheel sensor from the wheel hub. Failure
to do so may result in damage to the wheel sensor wires making the sensor
inoperative.
- Pull out the wheel sensor, being careful to turn it as little
as possible. Do not pull on the wheel sensor
harness.
- Before installation, check if foreign objects such as iron fragments are
adhered to the pick-up part of
the sensor or to the inside of the hole in the wheel hub for the wheel
sensor, or if a foreign object is caught in the surface of the mating
surface for the sensor rotor. Clean as necessary and then install
the wheel sensor.

P0116 ECT sensor
Description
The engine coolant temperature sensor is used to detect the engine
coolant temperature. The sensor modifies a voltage signal from the
ECM. The modified signal returns to the ECM as the engine coolant
temperature input. The sensor uses a thermistor which is sensitive to
the c ...
