This procedure covers the replacement of a suspension height sensor on the 2019-2024 Toyota RAV4 2.5L I4 FWD. Note: The standard RAV4 does not come equipped with air suspension; this procedure assumes an aftermarket air suspension system has been installed.

Warnings

Tools required

Parts

• Air suspension height sensor × 1 — Match to aftermarket air suspension system manufacturer
• Mounting hardware (if corroded) × 1 — Use OEM specification

Preparation

1. Park vehicle on level ground and engage parking brake
2. Place wheel chocks behind rear wheels
3. If equipped, disable air suspension system via dashboard control or by disconnecting power to air compressor
4. Allow air suspension to exhaust completely to normal ride height or deflated position per manufacturer instructions
5. Loosen wheel lug nuts on the wheel corresponding to the faulty sensor (typically rear suspension for height sensors)

Procedure

1. 1

   Raise and secure vehicle
   Lift the corner of the vehicle where the faulty height sensor is located using a floor jack at the appropriate jacking point. Raise vehicle to working height and secure with a jack stand. Remove the wheel completely.
2. 2

   Locate the height sensor assembly
   Identify the height sensor, typically mounted on or near the rear suspension control arm, strut assembly, or axle beam. The sensor will have a connecting link arm attached to a moving suspension component and an electrical connector. Trace the wiring harness to confirm sensor location.
3. 3

   Disconnect electrical connector
   Locate the electrical connector for the height sensor. Press the release tab and carefully disconnect the connector from the sensor. If connector is corroded or difficult to remove, spray with electrical contact cleaner and allow to penetrate before attempting removal.
4. 4

   Disconnect sensor link arm
   Identify the link arm connection point between the sensor and the suspension component (typically a ball socket or clip connection). Using a flathead screwdriver if necessary, carefully pry or unclip the link arm from the suspension mounting point. Note the orientation and position for reinstallation.
   ⚠Do not force the link arm disconnect. Excessive force can damage the mounting point on the suspension component.
5. 5

   Remove sensor mounting fasteners
   Remove the bolts or screws securing the height sensor body to its mounting bracket on the vehicle frame or suspension component. Typical mounting uses 2-3 bolts. Support the sensor while removing the final fastener to prevent it from falling.

   Mounting Bolts27 Nm (20 lb-ft)
6. 6

   Remove sensor from vehicle
   Carefully remove the height sensor assembly from the vehicle. If the wiring harness is secured with clips or ties to the suspension or frame, release these to allow sensor removal. Keep track of all mounting hardware and note routing of wiring harness.
7. 7

   Prepare new sensor for installation
   Unpack the new height sensor and verify it matches the removed unit in terms of connector type, link arm length, and mounting configuration. Apply a small amount of dielectric grease to the electrical connector on the new sensor to prevent corrosion.
8. 8

   Install new sensor to mounting bracket
   Position the new height sensor on its mounting location, ensuring proper orientation. Thread mounting bolts by hand first to prevent cross-threading. Tighten mounting bolts to specification using a torque wrench.

9. 9

   Connect sensor link arm
   Attach the sensor link arm to the suspension mounting point, ensuring it clicks or seats fully into place. Verify the link arm moves freely through its range of motion without binding. The sensor should be at approximately mid-range position when the suspension is at normal ride height.
10. 10

    Connect electrical connector and secure wiring
    Reconnect the electrical connector to the new height sensor, ensuring it clicks into place securely. Route the wiring harness following the original path and secure with new wire ties as needed, keeping wiring away from moving suspension components, exhaust, and sharp edges.
11. 11

    Reinstall wheel
    Reinstall the wheel, threading lug nuts by hand initially. Lower vehicle slightly so wheel contacts ground but vehicle weight is not fully on wheel. Tighten lug nuts in a star pattern to specification using torque wrench.
    Torque spec

    Wheel Lug Nuts136 Nm (100 lb-ft)
12. 12

    Lower vehicle and perform final checks
    Remove jack stand and carefully lower vehicle to ground. Reconnect air suspension power if it was disconnected. Start the vehicle and allow the air suspension system to initialize and calibrate the new sensor per manufacturer instructions (may require cycling ignition or using diagnostic tool).

Reassembly

1. Ensure all electrical connections are secure and properly routed away from moving components
2. Verify all mounting hardware is torqued to specification
3. Confirm sensor link arm has full range of motion without interference
4. Allow air suspension system to fully calibrate before driving

Verification

• Start vehicle and verify air suspension system operates normally with no warning lights on dashboard
• If equipped with level display, confirm vehicle sits at proper ride height on all corners
• Cycle suspension through height adjustments (if applicable) and verify smooth operation
• Road test vehicle at low speed and verify stable ride height is maintained
• Use diagnostic scanner if available to verify height sensor is reading correctly and no fault codes are present
• Inspect sensor area after test drive to ensure no wiring has come loose or shifted
