Repair Procedures

Removal

Be careful not to damage parts located under the vehicle (floor under cover, fuel filter, fuel tank, and canister) when lifting the vehicle with a lift. (Refer to General Information - Jack Lifting Points and Support Points)

1. 1
   Loosen the wheel nuts slightly. Raise the vehicle and make sure it is securely supported.
2. 2
   Remove the front wheel and tire (A) from the front hub.

   Tightening torque: 107.9–128 N·m

   Be careful not to damage the hub bolts when removing the front wheel and tire (A).

   

3. 3
   Remove the front wheel guard. (Refer to Body - "Front Wheel Guard")
4. 4
   Disconnect the front wheel speed sensor connector (A), then remove the retaining clip (B).

   

5. 5
   Remove the bolt (A) of the front wheel speed sensor cable bracket.

   Tightening torque: 19.6–29 N·m

   

6. 6
   Loosen the bolt and disconnect the front wheel speed sensor (A).

   Tightening torque: 6.9–10.8 N·m

   

Installation

1. To install, reverse the removal procedure.

Inspection

1. 1
   Measure the output voltage between the wheel speed sensor terminal and body ground.

   To protect the wheel speed sensor, use a 100 Ω resistor when measuring the output voltage, as shown in the illustration.

   

2. 2
   Compare the change in the wheel speed sensor output voltage with the normal output voltage change, as shown below.

   

   V_low: 0.59–0.84 V V_high: 1.18–1.68 V Frequency range: 1–2,500 Hz
