Delphi SS21571 ABS Wheel Speed Sensor - Rear Left

Delphi ABS Wheel Speed Sensor SS21571

Delphi SS21571 is a rear left ABS wheel speed sensor built for direct replacement service on select Nissan applications. It uses a 1-connector, 3-terminal blade-style design with a female connector and included wiring harness for a clean OE-style repair.

Compatible with 2012-2019 Nissan Versa and 2014-2019 Nissan Versa Note, this ABS wheel speed sensor is calibrated to OE standards to support accurate wheel speed input for the braking system. Delphi validates its sensors through OE development methods to help maintain consistent signal quality and reduce repeat repairs.

Detailed Description

Delphi SS21571 is an ABS wheel speed sensor for rear left applications on Nissan Versa and Nissan Versa Note models listed in the fitment data. It is engineered as a standard replacement part with OE-calibrated output, helping the ABS control system receive accurate wheel speed information. The sensor measures 25.3 in. overall length and includes a 21.18 in. wiring harness, or 538 mm as listed in the product data, for routing flexibility during service. This part cross-references Standard Ignition ALS2244 for the same application.

What It Helps Address

• ABS warning light caused by a failed rear wheel speed sensor
• Erratic or missing wheel speed signal at the rear left wheel
• Brake system fault codes related to wheel speed input
• Loss of ABS function from sensor circuit damage or wear
• Repeat repairs caused by inaccurate sensor readings

Installation Notes and Tips

Verify rear left position, connector style, and harness routing before installation. Inspect the tone ring, wiring, and connector terminals for corrosion or damage before replacing the sensor. Use the included instruction sheet during installation and confirm proper sensor seating and secure harness routing after service.

Quality Assurance

Delphi backs this sensor with OE development and product validation methods, and each sensor is tested and calibrated to OE standards for accurate readings. That validation focus supports consistent performance on Nissan Versa and Nissan Versa Note brake system repairs.
