3) Remove the primary speed sensor.

B: INSTALLATION

CAUTION: Be sure to prevent water or oil from contacting the connector terminal of primary speed sensor. If adhesion occurs, replace with a new part.

Install in the reverse order of removal.

NOTE:

• Use new O-rings.
• Apply CVTF to the O-ring.

Tightening torque: 5 N*m (0.5 kgf-m, 3.7 ft-lb)

C: INSPECTION

1) Remove the instrument panel lower cover. <Ref. to EI-64, REMOVAL, Instrument Panel Lower Cover.>

2) Set the probe of oscilloscope to TCM harness connector.

Connector & terminal (B54) No. 6 (+) - No. 1 (-):

1. + probe
2. - probe

3) Start and warm up the engine.

4) Check the waveform of primary speed sensor with engine idling.

Front Wheel Speed Sensor

A: REMOVAL

CAUTION:

• Be sure to prevent water or oil from contacting the connector terminal of front wheel speed sensor.

  If adhesion occurs, replace with a new part.

• When removing front wheel speed sensor, CVTF may let out. If CVTF has leaked, adjust the CVTF level after installing the front wheel speed sensor.

1) Lift up the vehicle.

2) Clean the transmission exterior.

3) Remove the harness connector from front wheel speed sensor.

4) Remove the front wheel speed sensor.

B: INSTALLATION

CAUTION:

• Be sure to prevent water or oil from contacting the connector terminal of front wheel speed sensor.

  If adhesion occurs, replace with a new part.

• After installing the front wheel speed sensor, adjust the CVTF level.

Install in the reverse order of removal.

NOTE:

• Use new O-rings.
• Apply CVTF to the O-ring.

Tightening torque: 5 N*m (0.5 kgf-m, 5.2 ft-lb)

C: INSPECTION

1) Remove the instrument panel lower cover. <Ref. to EI-64, REMOVAL, Instrument Panel Lower Cover.>

2) Set the probe of oscilloscope to TCM harness connector.

Connector & terminal (B54) No. 20 (+) - No. 1 (-):

1. + probe
2. - probe

3) Lift up the vehicle and raise the vehicle speed up to 20 km/h (12 MPH).

4) Check the waveform of front wheel speed sensor when vehicle speed is at 20 km/h (12 MPH).

Secondary Pressure Sensor

A: REMOVAL

CAUTION:

• Be sure to prevent water or oil from contacting the connector terminal of secondary pressure sensor.

  If adhesion occurs, replace with a new part.

• When removing secondary pressure sensor, CVTF may let out. If CVTF has leaked, adjust the CVTF level after installing the secondary pressure sensor.

1) Remove the air intake boot assembly. <Ref. to IN(H4SO)-8, REMOVAL, Air Intake Boot.>

2) Remove the secondary pressure sensor connector.

3) Remove the secondary pressure sensor.

NOTE: Use Ko-ken 3/8 12-point 27 mm (manufacturer product No. 3305M-27) deep socket.

B: INSTALLATION

CAUTION:

• Be sure to prevent water or oil from contacting the connector terminal of secondary pressure sensor.

  If adhesion occurs, replace with a new part.

• After installing the secondary pressure sensor, adjust the CVTF level.

Install in the reverse order of removal.

NOTE: Use new O-rings.

Tightening torque: 39 N*m (4.0 kgf-m, 28.8 ft-lb)

C: INSPECTION

1) Remove the instrument panel lower cover. <Ref. to EI-64, REMOVAL, Instrument Panel Lower Cover.>

2) Start and warm up the engine.

3) Check the voltage of secondary pressure sensor with engine idling.
