Tools required

Parts

• Rear ABS wheel speed sensor × 1 — Use OEM Honda part number (57450-TVA-A01 or equivalent)

Preparation

1. Park vehicle on a level surface and engage parking brake
2. Place wheel chocks in front of the front wheels
3. Loosen the rear wheel lug nuts while the vehicle is on the ground
4. Lift the rear of the vehicle using the designated jacking points and support securely on jack stands
5. Remove the rear wheel on the side requiring sensor replacement

Procedure

1. 1

   Locate the ABS sensor
   The rear ABS wheel speed sensor is mounted on the rear knuckle assembly, behind the brake rotor and caliper. The sensor tip inserts into the knuckle bore and monitors the tone ring on the wheel hub bearing assembly. Visually inspect the sensor and wiring harness for any obvious damage.
2. 2

   Disconnect the sensor electrical connector
   Follow the sensor wire from the knuckle upward toward the wheel well. Locate the electrical connector, which is typically secured to a bracket on the trailing arm or lower control arm area. Press the locking tab and carefully disconnect the connector. Avoid pulling on the wire itself.
3. 3

   Release wire harness clips
   The sensor wire is routed along the suspension components and secured with plastic clips or retainers. Carefully release each clip by pressing the center tab or prying gently with a trim tool. Note the routing path for reinstallation. There are typically 2-3 clips along the trailing arm and knuckle.
4. 4

   Remove the sensor mounting bolt
   Using a 10mm socket, remove the single bolt securing the ABS sensor to the rear knuckle. The bolt is located at the rear of the knuckle assembly. If the bolt is corroded or difficult to remove, apply penetrating oil and allow it to soak for several minutes.

5. 5

   Extract the sensor from the knuckle
   Gently pull the sensor straight out of the knuckle bore. If the sensor is seized due to corrosion, carefully wiggle it while pulling. Do not pry against the sensor body as it is fragile plastic. If severely stuck, apply penetrating oil around the sensor body and allow it to penetrate before trying again.
6. 6

   Clean the sensor bore
   Use a wire brush or sandpaper to clean any corrosion or debris from the sensor mounting bore in the knuckle. Spray with brake cleaner to remove any remaining contaminants. The bore must be clean to ensure proper sensor seating and accurate readings. Check that the O-ring groove (if equipped) is also clean.
7. 7

   Prepare the new sensor
   Remove the new sensor from its packaging. Verify that the new sensor matches the old one in terms of connector type and physical dimensions. Apply a thin coat of dielectric grease to the sensor O-ring (if equipped) and to the connector terminals to prevent corrosion. Do not apply grease to the sensor tip itself.
8. 8

   Install the new sensor
   Insert the new sensor straight into the knuckle bore, ensuring it seats fully. The sensor should slide in smoothly without excessive force. Align the mounting hole and hand-thread the mounting bolt to prevent cross-threading.

9. 9

   Route and secure the wire harness
   Route the sensor wire along the original path, ensuring it does not contact any moving suspension components or sharp edges. Secure the wire with all original clips and retainers. Verify there is adequate slack for suspension movement and that the wire will not be pinched or stretched during suspension travel.
10. 10

    Connect the electrical connector
    Align the connector halves and push together firmly until the locking tab clicks into place. Gently tug on the connection to verify it is secure. Ensure the connector is properly seated in any mounting bracket.
11. 11

    Reinstall the wheel
    Place the wheel back onto the hub, aligning the lug nut holes. Thread all lug nuts by hand to prevent cross-threading. Tighten the lug nuts in a star pattern to approximately 50% of final torque while the vehicle is still raised.
    Torque spec

    Wheel Lug Nuts129 Nm (95 lb-ft)
12. 12

    Lower vehicle and final torque
    Lower the vehicle until the tire just contacts the ground but most weight is still on the jack stands. Using a torque wrench, tighten the lug nuts in a star pattern to the specified torque. Fully lower the vehicle and remove the jack stands.

Reassembly

1. Ensure all wire harness clips are properly secured and the routing matches the original configuration
2. Verify the sensor connector is fully locked and seated in its bracket
3. Double-check that the wheel lug nuts are torqued to specification

Verification

• Start the engine and verify the ABS warning light illuminates briefly during the bulb check, then extinguishes within 3-5 seconds
• If the ABS light remains on, use a scan tool to check for fault codes and verify the new sensor is communicating properly
• Test drive the vehicle at speeds above 12 mph (20 km/h) to allow the ABS system to self-test. The ABS light should remain off
• Perform a controlled low-speed ABS activation test in a safe area to confirm proper system operation
• Re-check wheel lug nut torque after 50-100 miles of driving
