This procedure addresses removal and replacement of the air suspension height sensor on a 2012-2017 Toyota Camry 2.5L I4. Note: This vehicle does not come equipped with air suspension from the factory; this procedure assumes an aftermarket air suspension system has been installed.

Warnings

Tools required

Parts

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

Preparation

1. Park vehicle on level ground and apply parking brake firmly
2. Place wheel chocks behind front wheels
3. If equipped with aftermarket air suspension controller, set system to normal ride height or disable auto-leveling
4. Depressurize air suspension system according to aftermarket system manufacturer instructions
5. Loosen rear wheel lug nuts while vehicle is on ground

Procedure

1. 1

   Raise and support vehicle
   Raise the rear of the vehicle using a floor jack at the manufacturer-designated jacking point. Once raised to working height, position jack stands under the frame rails or reinforced pinch welds. Lower the vehicle onto the jack stands and verify stability before proceeding.
2. 2

   Remove rear wheel
   Remove the rear wheel lug nuts completely and remove the wheel. Set wheel aside in a safe location. This provides access to the rear suspension components where the height sensor is mounted.
3. 3

   Locate height sensor
   Identify the height sensor on the rear suspension assembly. On aftermarket systems, the sensor is typically mounted to the chassis or suspension tower with a bracket, with a linkage arm connecting to the suspension control arm or trailing arm. Note the orientation and routing of the sensor linkage and electrical connector before removal.
4. 4

   Disconnect electrical connector
   Locate the electrical connector for the height sensor. Press the release tab and carefully disconnect the connector from the sensor. If the connector is corroded or difficult to remove, spray with electrical contact cleaner and allow to penetrate before attempting removal. Inspect connector terminals for corrosion or damage.
5. 5

   Disconnect sensor linkage arm
   Remove the linkage arm connection at the suspension component. This typically uses a ball joint style connection with a retaining clip or small bolt. Use a flathead screwdriver to pry the retaining clip off if applicable, or remove the mounting hardware. Note the exact position of the linkage arm for reinstallation.
6. 6

   Remove sensor mounting bolts
   Remove the mounting bolts securing the height sensor bracket to the chassis or suspension tower. Most aftermarket sensors use 2-3 mounting bolts. Support the sensor while removing the final bolt to prevent it from falling. Remove the sensor and bracket assembly from the vehicle.
7. 7

   Inspect mounting location
   Clean the mounting surface with a wire brush to remove rust, dirt, or corrosion. Inspect the mounting holes and surrounding area for damage or elongation. Check the linkage arm mounting point on the suspension for wear or damage. Replace any damaged mounting hardware.
8. 8

   Install new height sensor
   Position the new height sensor and bracket assembly to the mounting location, ensuring proper orientation matches the original installation. Start all mounting bolts by hand to ensure proper thread engagement. Torque mounting bolts to specification using a torque wrench.
   Torque spec

   Mounting Bolts27 Nm (20 lb-ft)
9. 9

   Connect sensor linkage arm
   With the suspension at normal ride height position, connect the linkage arm to the suspension mounting point. Ensure the linkage arm is at the same angle and position as noted during removal. Install the retaining clip or mounting hardware and verify the connection is secure with no binding through full suspension travel.
10. 10

    Connect electrical connector
    Clean the electrical connector terminals if necessary with electrical contact cleaner. Connect the electrical connector to the height sensor, ensuring it clicks into place and the locking tab engages fully. Gently tug on the connector to verify it is secure.
11. 11

    Reinstall wheel
    Position the wheel onto the hub and install lug nuts by hand. Tighten lug nuts in a star pattern using a torque wrench to specification.
    Torque spec

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

    Lower vehicle and final tightening
    Raise the vehicle slightly to remove jack stands, then carefully lower the vehicle completely to the ground. With full vehicle weight on the wheels, perform a final torque check on the wheel lug nuts in a star pattern.

    Wheel Lug Nuts136 Nm (100 lb-ft)

Reassembly

1. Ensure all electrical connections are fully seated and locked
2. Verify linkage arm moves freely through full suspension travel without binding
3. Double-check that all mounting hardware is torqued to specification
4. Route any wiring harnesses away from moving suspension components and sharp edges

Verification

• Start the vehicle and power on the air suspension system if equipped with a controller
• Verify the air suspension system recognizes the new sensor (check for warning lights or error messages on controller)
• Cycle the suspension through various height settings if applicable, verifying smooth operation
• Perform a test drive on level road and verify the vehicle maintains proper ride height
• Check for air leaks around all suspension components while system is pressurized
• Use diagnostic scan tool or air suspension controller to verify sensor is reading correctly and providing proper signal voltage
