What This Sensor Helps Address

• ABS warning light caused by a failing front wheel speed sensor
• Intermittent wheel speed signal loss at the front axle
• ABS system fault codes related to wheel speed input
• Traction control or stability control issues tied to wheel speed data
• Harsh or inconsistent ABS operation during braking events

Installation Notes and Tips

Verify the vehicle position before ordering, since the listed fitment includes front, front left, and front right applications depending on model. Compare the connector shape, terminal count, and harness routing to the original sensor before installation. Inspect the mounting area and surrounding wiring for corrosion, damage, or debris that could affect signal quality. For 2003-2006 Mercedes-Benz S430 and S500 applications, confirm the exact front position shown in the vehicle application tab.
