This procedure covers removal and replacement of the front ABS wheel speed sensor on a 2012-2017 Toyota Camry with the 2.5L I4 engine.

Warnings

Tools required

Parts

• Front ABS wheel speed sensor × 1 — 89542-06030 (Left) or 89543-06030 (Right)
• ABS sensor O-ring (if equipped) × 1 — Use OEM specification

Preparation

1. Park vehicle on level surface and engage parking brake
2. Place wheel chocks behind rear wheels
3. Loosen wheel lug nuts on the affected wheel 1/4 turn while vehicle is on ground
4. Raise front of vehicle and support securely on jack stands at manufacturer-designated lift points
5. Remove wheel completely

Procedure

1. 1

   Locate the ABS wheel speed sensor
   The ABS wheel speed sensor is mounted on the back side of the steering knuckle, near the top of the wheel hub assembly. The sensor wire runs up through routing clips toward the inner fender well. Identify the sensor body and its single mounting bolt (10mm head).
2. 2

   Disconnect sensor electrical connector
   Follow the sensor wire harness upward to locate the electrical connector, typically located in the wheel well area near the strut tower. Press the release tab and carefully disconnect the connector. If corroded, spray with electrical contact cleaner and allow to dry before disconnecting.
3. 3

   Release wire harness clips
   Trace the sensor wire from the connector to the sensor and carefully release any wire harness clips or routing brackets holding the wire in place. Note the exact routing path for reinstallation. Use a flathead screwdriver or trim tool if needed to release plastic clips without breaking them.
4. 4

   Remove ABS sensor mounting bolt
   Using a 10mm socket, remove the single bolt securing the ABS sensor to the steering knuckle. The bolt may be corroded; apply penetrating oil if needed and allow to soak for several minutes. Do not use excessive force that could damage the knuckle threads.
5. 5

   Extract the sensor from knuckle
   Carefully pull the sensor straight out of its bore in the steering knuckle. If sensor is seized, gently rotate while pulling. Do not pry against the sensor body or use excessive force. If completely seized, apply penetrating oil around the sensor body, wait 15 minutes, and try again. The sensor tip should slide out cleanly.
   ⚠Never strike the sensor or use pliers on the sensor body - this will damage internal components
6. 6

   Clean sensor mounting bore
   Use a wire brush to clean the sensor mounting bore in the steering knuckle, removing any rust, debris, or corrosion buildup. Ensure the bore is completely clean to allow proper sensor seating and accurate gap measurement. Wipe clean with a lint-free cloth.
7. 7

   Inspect reluctor ring
   With the sensor removed, visually inspect the reluctor ring (toothed ring) on the wheel hub assembly. Check for damage, missing teeth, excessive rust, or debris buildup. Clean with wire brush if dirty. Any damage to the reluctor ring requires wheel hub replacement.
8. 8

   Prepare new sensor for installation
   Inspect the new sensor O-ring (if equipped) for damage and ensure it is properly seated in the sensor body groove. Apply a thin coat of fresh brake fluid or dielectric grease to the O-ring to aid installation. Do not use petroleum-based lubricants.
9. 9

   Install new ABS sensor
   Carefully insert the new sensor straight into the mounting bore in the steering knuckle. Push firmly until the sensor is fully seated and the mounting ear is flush against the knuckle surface. Ensure the sensor tip is properly aligned with the reluctor ring teeth with no contact.
10. 10

    Install and torque sensor mounting bolt
    Insert the mounting bolt and thread by hand to ensure proper alignment. Using a torque wrench, tighten the ABS sensor bolt to exactly 10.0 Nm (7.0 lb-ft). This is a critical specification - overtightening will strip the aluminum threads in the knuckle.
    ⚠️Do not exceed 10.0 Nm torque specification - overtightening will strip threads and require steering knuckle replacement

11. 11

    Route and secure sensor wiring
    Route the sensor wire harness along the original path noted during removal. Ensure the wire is not twisted, kinked, or routed near any heat sources or moving components. Secure all routing clips and brackets in their original positions. Verify adequate slack for suspension travel.
12. 12

    Reconnect electrical connector
    Apply a small amount of dielectric grease to the sensor connector terminals (optional but recommended for corrosion protection). Reconnect the electrical connector and ensure it clicks firmly into place. Gently tug to verify secure connection.
13. 13

    Reinstall wheel
    Reinstall the wheel and hand-thread all lug nuts to prevent cross-threading. Using a torque wrench in a star pattern, torque the wheel lug nuts to 136.0 Nm (100.0 lb-ft). Lower the vehicle and perform final torque verification with vehicle weight on the ground.

Reassembly

1. Ensure sensor wire routing does not interfere with suspension components through full range of motion
2. Verify all wire harness clips are securely fastened
3. Double-check that sensor mounting bolt is torqued to specification and not overtightened

Verification

• Start the vehicle and verify the ABS warning light illuminates briefly during bulb check, then extinguishes within a few seconds
• Using an OBD-II scanner, check for ABS diagnostic trouble codes - there should be no active codes related to the replaced sensor
• Test drive the vehicle at speeds above 10 mph to allow the ABS system to verify sensor signal - ABS light should remain off
• Perform a controlled low-speed ABS activation test in a safe area if possible to confirm proper sensor operation
• If ABS light remains illuminated, re-check sensor installation, electrical connector, and wire routing for damage
