• Brake system diagnostic trouble codes linked to front sensor failure

Installation Notes and Tips

Verify connector shape, terminal style, and harness length against the original sensor before installation. Inspect the wheel hub area, tone ring, and wiring path for corrosion, debris, or physical damage that could affect the new sensor signal. Confirm the vehicle application by year, make, model, and front position before ordering.
