Detailed Description

Delphi SS21357 is an ABS wheel speed sensor engineered for front-wheel applications on select Nissan vehicles. It is listed for 2007-2013 Nissan Altima, front, and 2009-2014 Nissan Maxima, front. This sensor uses a rectangular male connector, blade terminals, and a supplied wiring harness to match the original electrical interface on the vehicle. Delphi calibrates and tests its sensors to OE standards, helping maintain reliable wheel-speed data for the ABS system. If you are replacing a failing front ABS sensor on a Nissan Altima or Nissan Maxima, SS21357 provides a direct replacement option with the correct connector and terminal layout.

This part cross-references Standard Ignition ALS1442 for the same application.

What It Helps Solve

• ABS warning light caused by a failed front wheel speed sensor
• Erratic or missing wheel-speed signal input
• ABS system fault codes related to the front sensor circuit
• Brake control issues tied to inaccurate wheel-speed readings
• Intermittent sensor connection problems at the front axle

Installation Notes and Tips

Verify connector shape, terminal count, and front-position fitment before installation. Inspect the harness routing and sensor mounting area for corrosion, debris, or damaged wiring that could affect signal quality. Because mounting hardware is not included, reuse or source the required hardware as needed. Confirm the vehicle application against the listed fitment for 2007-2013 Nissan Altima front and 2009-2014 Nissan Maxima front before final assembly.

Quality Assurance

Delphi sensors are developed and validated using OE-focused methods and are tested and calibrated to OE standards for accurate readings. That process supports dependable ABS system performance and helps reduce repeat repairs.
