Detailed Description

Delphi SS21503 is an ABS wheel speed sensor engineered for front-position use on Tesla Model 3 and Tesla Model Y vehicles within the listed model years. Delphi validates its vehicle sensors to OE standards and calibrates them for accurate readings, helping maintain reliable wheel speed signal output for the ABS system. This part cross-references Monroe Shocks & Struts (e.g., 1188761-00-A) for the same application.

For buyers searching for a front ABS wheel speed sensor for Tesla Model 3 or a Tesla Model Y front wheel speed sensor, this Delphi replacement provides the specified connector style, terminal layout, and harness length details needed for a proper match. The SS21503 part number is also useful when verifying the correct sensor against service records or existing component markings.

What It Helps Address

• ABS warning light caused by a faulty front wheel speed sensor
• Intermittent or inaccurate wheel speed signal readings
• Traction control or stability system faults tied to wheel speed input
• Brake system diagnostic trouble codes related to the front sensor circuit
• Drivability concerns linked to inconsistent ABS data

Installation Notes and Tips

Confirm front-position fitment before ordering and match the connector shape, terminal count, and harness routing to the original sensor. Inspect the wheel hub area, wiring path, and connector condition before installation, and clear any stored ABS codes after replacement if required by the vehicle service procedure. Verify the part number SS21503 against the removed sensor and vehicle application data for Tesla Model 3 and Tesla Model Y front fitment.

Quality Assurance

Delphi sensors are developed and validated using OE-focused methods and tested to OE standards for accurate signal output. That calibration process supports consistent performance in the ABS system and helps reduce repeat repairs.
