OE-Style Sensor Performance

Delphi SS21450 is engineered for front-wheel ABS monitoring on the Dodge Durango and Jeep Grand Cherokee. The sensor is calibrated to OE standards to support accurate wheel speed signal output, which is critical for ABS operation, traction control response, and stable brake system communication. This part number, SS21450, also cross-references Standard Ignition ALS2902 for the same application.

Common Problems This Sensor Can Address

• ABS warning light triggered by a failed front wheel speed sensor
• Intermittent wheel speed signal loss at the front axle
• Traction control or stability system faults tied to wheel speed input
• Brake system scan codes related to front sensor performance
• Erratic ABS operation caused by damaged sensor wiring or connector wear

Installation Notes and Tips

Verify the connector style, harness length, and front position before installation. SS21450 includes a wiring harness and uses a 2-terminal blade connection with an oval 2-connector layout. Inspect the tone ring, hub area, and harness routing during replacement to confirm the new sensor can read a clean signal. Confirm vehicle year, make, model, and front position against the fitment list before ordering.

Quality Assurance

Delphi sensors are developed and validated using OE-level methods and tested to OE standards for accurate readings. That validation focus helps support consistent sensor output and reduces the chance of repeat repairs on front ABS wheel speed sensor service.
