Detailed Description

This ABS wheel speed sensor monitors wheel rotation and sends the signal needed by the anti-lock brake system to manage braking response. Delphi SS11721 is specified for 1995-1997 Lincoln Town Car, 1995-1997 Mercury Grand Marquis, and 1995-1996 Ford Crown Victoria applications in the front left or front right position, as listed in the fitment data. For the exact side on your vehicle, refer to the application tab.

Use this sensor when servicing a vehicle with an ABS warning light, erratic wheel speed data, or a failed front wheel speed sensor on the listed Ford, Lincoln, and Mercury platforms. The OE-style connector layout and integrated harness support a straightforward replacement of the original sensor assembly.

What It Helps Address

• ABS warning light caused by a failed front wheel speed sensor
• Intermittent or inaccurate wheel speed signal input
• Brake system fault codes related to the front sensor circuit
• Loss of anti-lock brake function at the affected wheel
• Harness or connector wear at the sensor assembly

Installation Notes and Tips

Confirm the correct side before ordering, since this part is used on both front left and front right positions depending on the vehicle. Verify connector shape, terminal count, and harness length against the original sensor before installation. Clean the mounting area and inspect the tone ring, wiring path, and connector terminals for damage that could affect the new sensor signal.
