  • Sensor wear from road debris, water, or salt intrusion
  • Damage from impact or accident-related suspension movement

Installation Notes and Tips

Verify rear left fitment before installation on the 2005-2007 Toyota Sequoia. Inspect the linkage and mounting points for corrosion, debris, or damage before transferring the new sensor into service. Confirm connector style, terminal type, and wire count match the original unit before final assembly.
