Warnings

Tools required

Parts

• Front ABS wheel speed sensor × 1 — Use OEM Rivian specification
• Sensor mounting bolt × 1 — Use OEM specification if damaged
• Sensor wiring harness clips × 1 — As needed if damaged

Preparation

1. Park vehicle on level ground and apply parking brake
2. Place wheel chocks behind rear wheels
3. Disconnect 12V battery negative terminal and wait 2 minutes for system capacitors to discharge
4. Loosen front wheel lug nuts before lifting vehicle
5. Raise vehicle and secure on jack stands at manufacturer-specified lift points
6. Remove front wheel from affected side
7. If testing existing sensor, have diagnostic scan tool ready to read ABS codes and sensor data

Procedure

1. 1

   Access the wheel speed sensor connector
   Locate the ABS wheel speed sensor electrical connector in the wheel well area. On the EDV 500, the connector is typically secured to the chassis or suspension component with a retaining clip. Note the connector routing for proper reinstallation.
2. 2

   Disconnect the sensor electrical connector
   Press the connector release tab and carefully separate the wheel speed sensor connector from the vehicle harness. If connector is corroded or difficult to separate, apply contact cleaner and work gently to avoid breaking the connector. Inspect connector pins for corrosion or damage.
3. 3

   Release wiring harness clips
   Follow the sensor wire from the connector to the sensor. Release all retaining clips securing the sensor wire to the brake line, suspension components, or chassis. Note the exact routing path and clip locations for reinstallation. On the EDV 500, there are typically 2-3 clips along the wire path.
4. 4

   Clean around sensor mounting area
   Use a wire brush to clean around the sensor mounting bolt and the area where the sensor enters the steering knuckle or hub bearing assembly. Remove any accumulated dirt, road salt, or corrosion to prevent contamination from falling into the sensor bore during removal.
5. 5

   Remove sensor mounting bolt
   Remove the single bolt securing the ABS wheel speed sensor to the knuckle or hub assembly. The bolt is typically M6 or M8 size. If bolt is corroded or seized, apply penetrating oil and allow to soak for several minutes before attempting removal. Keep bolt if in good condition for reuse, or replace if damaged.
6. 6

   Extract the wheel speed sensor
   Carefully pull the sensor straight out of the mounting bore in the knuckle/hub assembly. If sensor is stuck due to corrosion, gently rotate while pulling. Do not use excessive force or pry against the sensor body as it may break. If severely seized, apply penetrating oil around the sensor body and allow to soak, then try again. Avoid hitting the sensor with a hammer as this can break the sensor internally.
7. 7

   Inspect and clean the sensor bore
   Once sensor is removed, inspect the bore in the knuckle/hub for damage, corrosion, or metal debris. Clean the bore thoroughly with a wire brush or appropriate cleaning tool. Ensure the bore is clean and smooth. Any metal particles left in the bore can stick to the magnetic sensor tip and cause erratic readings or ABS faults.
8. 8

   Inspect the tone ring
   Visually inspect the ABS tone ring (reluctor ring) on the CV axle shaft or hub bearing for damage, missing teeth, or excessive rust buildup. The tone ring should have evenly spaced teeth with no cracks or missing sections. Clean any rust or debris from the tone ring surface if present. A damaged tone ring will require additional repair beyond sensor replacement.
9. 9

   Prepare new sensor for installation
   Remove new sensor from packaging and inspect for shipping damage. Verify sensor tip is clean and undamaged. Compare new sensor with old sensor to confirm correct part. Apply a thin coating of dielectric grease to the sensor O-ring or body (if equipped with O-ring seal) to ease installation and prevent future corrosion. Do not apply grease to the sensor tip itself.
10. 10

    Install new wheel speed sensor
    Carefully insert the new sensor straight into the mounting bore in the knuckle/hub assembly. Push sensor fully into place until it seats against the mounting flange. Ensure sensor is properly aligned and fully seated before installing mounting bolt. Verify proper air gap by checking that sensor sits at correct depth per manufacturer specification.
11. 11

    Install and tighten sensor mounting bolt
    Install the sensor mounting bolt and hand-tighten initially. Since no torque specification is provided in the database, tighten the sensor mounting bolt firmly but do not over-torque. Typical ABS sensor mounting bolts require 7-10 ft-lbs. The bolt should be snug enough to secure the sensor without movement, but not so tight as to crack the sensor body or strip the threads in the aluminum knuckle.
12. 12

    Route and secure sensor wiring
    Route the sensor wire back along the original path, ensuring it follows the same routing as noted during removal. Secure the wire with all original retaining clips, ensuring the wire is not stretched tight, kinked, or routed where it can contact moving suspension components or the tire. Maintain proper clearance from the CV axle, brake caliper, and steering components throughout the suspension travel range.
13. 13

    Reconnect electrical connector
    Reconnect the wheel speed sensor electrical connector to the vehicle harness. Ensure the connector locks fully with an audible click. Gently tug on the connection to verify it is secure. Apply dielectric grease to the connector if working in harsh conditions to prevent future corrosion.
14. 14

    Reinstall wheel and lower vehicle
    Reinstall the front wheel, hand-tightening lug nuts in a star pattern. Lower vehicle from jack stands and remove jack. Once vehicle weight is on the wheel, torque lug nuts to manufacturer specification (typically 140-160 ft-lbs for the EDV 500) in a star pattern.
15. 15

    Reconnect battery and clear codes
    Reconnect the 12V battery negative terminal. Use a diagnostic scan tool to clear any stored ABS fault codes from the system. This ensures the ABS system recognizes the new sensor and allows proper verification testing.

Reassembly

1. Ensure sensor mounting bolt is secure but not over-tightened
2. Verify all wiring harness clips are installed and sensor wire routing matches original path
3. Confirm electrical connector is fully locked with no exposed terminals
4. Double-check wheel lug nuts are torqued to specification

Verification

• With diagnostic scan tool, verify the new wheel speed sensor is providing a signal and reading properly
• Check for any active or pending ABS fault codes; there should be none related to the replaced sensor
• Perform a test drive at low speed (5-10 mph) in a safe area and verify the ABS warning light does not illuminate
• During test drive, monitor wheel speed sensor readings with scan tool if possible; all four sensors should show similar readings when driving straight
• Perform a controlled ABS activation test in a safe area if qualified to do so, or have customer return if ABS warning light illuminates during normal driving
• Verify sensor wiring does not contact tire or moving suspension components during steering and suspension movement
